Toby Gorman 

As the new year arrives it brings with 

it change, optimism, and a little bit of 

uncertainty. This is what we celebrate as the 

calendar flips from 2018 to 2019. It’s a time 

to reflect on all that has been accomplished 

over the past year and prepare for the 

challenges that lay ahead. 

Here at Maximum Yield, 2018 was a year of 

challenges, accomplishments, and change. 

As the grow industry landscape changed as 

never before, we, too, had to change. 

We restarted with rebuilding our distribution 

system so that Maximum Yield was directly 

distributed via FedEx to hydro stores, 

ensuring trackable distribution. This allows 

us to pinpoint exactly how many copies are 

going out and where they’re going, while 

maximizing our reach so as many readers 

as possible can benefit from the helpful 

information found within the magazine. For a 

current map of where to find Maximum Yield, 

check out maximumyield.com. Of course, 

magazines distributed through our hydro 

retail partners are still free. 

To complement our hydro store distribution, 

we also entered mainstream retail distribution 

to engage an even broader audience. In the 

US, readers can now find Maximum Yield 

and Maximum Yield Cannabis at Barnes 

and Noble, our first foray in 21 years onto the 

newsstand. To make this work, we had to 

rebrand some of our magazines, so we went to 

work with sleek new cover designs, improved 

layout design, and cutting-edge content from 

some of the industry’s best writers. 

In modern day publishing, however, print isn’t 

enough. In 2018 we also upgraded our website, 

introduced our MY app, and increased our 

social presence so our articles and products can 

reach you no matter where you are. 

We’re not done yet, and we can’t wait to see 

what 2019 brings. With that said, from the 

Maximum Yield team to you and yours, we 

wish you a 2019 filled with joy, happiness, 

and beautiful gardens.

Enzymes 

Enzymes are biological catalysts. This means that enzymes accelerate a wide variety 

of very particular chemical reactions within living organisms. They represent a major 

aspect of cellular regulation and function. Almost all metabolic processes including 

transportation of information and processes within the cytoskeleton of the cell need 

enzymes in order to maintain function and sustain the life of the organism. 

Chemically, enzymes are like any catalyst and are not consumed in chemical 

reactions, nor do they alter a reaction other than through acceleration. Enzymes differ 

from most other catalysts by being much more specific in their function and reaction. 

The molecules upon which enzymes may act are called substrates and the enzyme 

helps convert the substrates into different molecules known as products. Enzyme 

activity can be affected by other molecules: inhibitors are molecules that decrease 

enzyme activity, and activators are molecules that increase activity.

Durability Meets Design. 

That’s the secret. 

Geopot is designed with your 

plants in mind. Its breathable 

fabric container air prunes your 

plants’ roots when they reach the 

end of the container. 

The air root-pruning process 

allows the roots to branch out 

with more fibrous feeder roots. 

And guess what? More roots 

means better flowers. And better 

flowers make happier gardeners. 

But we’re not done yet. The 

quad stitched, UV-Treated fabric 

is the thickest on the market, 

ensuring longevity while still 

allowing for excellent drainage 

and airflow in your garden.

GROWER 

Q 

What proportion of plant hormones should we add for chili pepper plants? 

Thanks, 

Surya P. 

a 

Hello Surya, 

The type of concentration of plant hormones (plant 

growth regulators) to use on chili pepper plants 

depends on what process you are trying to control. 

Plant hormones are not routinely used for the general 

production of greenhouse and hydroponic chili plants 

under normal growing conditions as the plant produces 

sufficient amounts of these for optimal growth, and 

there is a risk that incorrect application can actually 

have a negative effect and may even kill or severely 

harm plants. The main use of plant hormones on chili 

plants is under adverse growing conditions, such as 

high or low temperatures where application helps 

reduce flower drop thus increasing fruit set and yields. 

Under adverse growing conditions chili crops can have 

a significant reduction in growth and yields when 

high daytime temperatures (more than 86°F) coupled 

with warm nights cause abscission of flowers 

and poor fruit set which severely restricts yields. 

The application of foliar sprays of the NAA 

(Naphthaleneacetic acid) auxin can enhance fruit set 

and yields under these conditions and make the crop 

more profitable. One study has also found that use 

of NAA at foliar-applied rates of 20-40 ppm not only 

improved fruit set, but also increased plant height and 

the number of primary branches in chili plants. However, 

other studies show varying responses to applied plant 

growth regulators, so some experimentation may be 

required. Other plant growth regulators that may have 

an effect on chili pepper plants have been reported as 

being GA3 (Gibberellic acid) at 10 ppm, and triacontanol 

at 5 ppm, which both had a similar effect to NAA by 

promoting greater fruit set and resulting yields under 

adverse environmental conditions.

FACTS 

Research Shows Climate Change Intensified Destructive Hurricanes 

Some of the nastiest recent hurricanes, including Katrina, Irma, and Maria were made more 

destructive by climate change, with as much as 10 per cent more rainfall. Research published in the 

journal Nature showed warming of the atmosphere and Atlantic, Pacific, and Indian oceans increased 

rainfall by five to 10 per cent, though wind speeds didn’t change much. But the problem will be worse 

with future global warming. Researchers discovered that if little is done to curb greenhouse gas emissions 

and the globe warms by 2-3°F, then hurricane rain would increase by a third with wind speeds boosted by as 

much as 29 miles per hour. “Climate change has exacerbated rainfall and is set to enhance the wind speed,” says 

Christina Patricola, who undertook the study with Lawrence Berkeley National Laboratory colleague Michael Wehner. 

The research used climate models to see how factors such as air and ocean temperatures have influenced hurricanes. 

Projections were then made, based upon various levels of planetary warming.

Scientists Create Drought-resistant Plants Without Stunting Growth 

Researchers have discovered a strategy to create drought-resistant plants without affecting 

overall plant growth. Ana Caño-Delgado led a team from the Center for Research in 

Agricultural Genomics (CRAG) that published a study in the journal Nature 

Communications detailing the discovery. Plants were created to resist 

drought by modifying the signaling of plant steroids called 

brassinosteroids. Initially these plants had stunted growth, 

but now Caño-Delgado has learned that plants which 

overexpress the BRL3 brassinosteroid receptor in the 

vascular tissue are more resistant to water scarcity 

than control plants and that, unlike the previously 

researched mutants, they grow to normal size. “We 

have discovered that modifying brassinosteroid 

signaling only locally in the vascular system, we 

are able to obtain drought resistant plants without 

affecting their growth,” says Caño-Delgado. The 

work was done on the plant Arabidopsis thaliana. 

It’s a small flowering plant found in Eurasia and 

Africa and is regarded as a weed.

Weed-eating Goats do Pesticide Work in Canadian City 

After banning the use of herbicides in public parks, the city of Edmonton 

has brought in 400 goats to feast on unwanted weeds growing in 

greenspaces. They feasted on leafy spurge, an invasive species 

with bunched yellow flowers in Rundle Park. Edmonton banned 

herbicides and have used goats to keep the weeds at bay. “The 

fact that we give an environmentally conscious alternative to 

the use of herbicides, I think that is really something amazing 

that is about this project,” says Joy Lakhan, goat coordinator with 

the City of Edmonton. The best part about using goats is they have a 

special digestive tract that can reduce germination in some plants, plus they can 

gobble 10 pounds of weeds a day. When they’re young, the goats are trained to target 

key weed species that can be harmful to other plants and animals. Enzymes in their 

body can break down parts of plants that could irritate other livestock.

FACTS 

New Heat System Turns Human Excrement into Fertilizer 

Innovative research from an Israel university has led to a process of using 

a specialized heating process to convert human excrement into fertilizer. 

Scientists at Ben-Gurion University of the Negev in Israel discovered the 

process known as hydrothermal carbonization (HTC), which address two large 

challenges faced by developing countries: sanitation and a demand for energy. 

The HTC system heats raw human excrement in a specially designed “pressure 

cooker” and the emerging product is hydrochar: a biomass fuel that looks like 

charcoal. The study, published in the Journal of Cleaner Production, shows how 

HTC heats raw human excrement to 356°F, 410°F, and 464°F for 30, 60, and 120 minutes. 

The waste gets dehydrated and turns into hydrochar, which is sterile. Hydrochar can then 

be made into “coals” for heating and cooking, while the liquid can be used to make fertilizer 

because it’s rich in nitrogen, phosphorus, and potassium.

California Reigns as World’s Biggest Almond Producer 

If you buy almonds, chances are they were grown in California. The 

Golden State is the largest producer of the tasty drupes and America 

produces the most in the world. In fact, California is the only place in 

the US that commercially grows almonds. The state’s harvest is usually 

enough to feed the nation and export to other countries. The US 

produces more than two million tons of almonds every year. About 70 

per cent of American almonds are exported in shelled form, with the rest 

sold unshelled (an almond is like a peach but instead of the fruity part 

becoming fleshy, most of it sizes up in the kernel). The California area is 

perfect since almonds grow best in a mild climate with plenty of sunshine 

and fertile soils. Spain (200,000 tons), Iran (147,000 tons), and Morocco 

(112,000 tons) round out the top global almond-producing nations.

Bacterial Resistance to Pesticides and Antibiotics Reaches Planetary Boundary 

A report suggests a group of bacteria has passed a planetary boundary (“safe operating space for 

humanity”) when it comes to resisting antibiotics and pesticides. Research from the journal Nature 

Sustainability concludes Gram-negative bacteria, including E. coli and salmonella, are resistant to 

all or most antibiotics tested. Lead researcher Peter Søgaard Jørgensen from the Royal Swedish 

Academy of Sciences and Stockholm Resilience Centre at Stockholm University suggests 

this type of resistance means societies will face large-scale agricultural and 

health crises. “It appears as if we have crossed a tipping point 

for Gram-negative bacteria, with doctors increasingly 

reporting untreatable infections. We now need to manage 

these ‘nightmare bacteria’ differently,” says Søgaard 

Jørgensen. Pesticide resistance is also a major concern, 

particularly resistance to glyphosate (the core 

ingredient in Roundup) and insecticidal Bt-toxins 

in transgenic crops. The research suggests some 

herbicides and Bt toxins have reached regional 

boundaries with some farming areas reporting 

large-scale resistance to these pesticides.

Why Washing 

Lettuce Won’t 

Remove E. Coli Risk 

With the recent E. coli 

outbreak in the US 

and Canada, experts 

warn that washing 

lettuce won’t remove 

the potentially deadly 

bacteria. Even scrubbing 

the lettuce with baking 

soda and vinegar will not 

work. That’s because the 

bacteria can get trapped in 

“microscopic crevices,” says 

James Rogers, director of Food 

Safety and Research at Consumer 

Reports. Even pre-washed lettuce that’s been triple 

washed isn’t safe for consumption. Thinking about 

cooking your greens? Wilting lettuce can’t guarantee all 

the bacteria is gone. It takes just 10 E. coli cells for a person 

to get sick and, by way of comparison, a pinhead can hold 10 

billion cells. And organic lettuce doesn’t necessarily mean it’s free 

from potential contamination. E. coli symptoms include stomach 

cramps, bloody diarrhea, and vomiting. Some cases can be lifethreatening. 

An outbreak in April last year, also from Romaine 

lettuce, killed five people and infected 210 others across 36 states.

Portland Named Best Foodie City in US 

Thanks in part to its abundance of farmers markets and communitysupported 

agriculture programs, Portland, OR, earned the title 

of Best Foodie City in a report from personal finance website 

Wallethub. Finishing second was San Francisco, followed by Miami. 

“Portland ranked first for several metrics including accessibility 

and affordability of high-quality restaurants and the lack of sales, 

food, and restaurant taxes. Portland also has the highest number 

of food trucks, craft breweries, wine bars, 

and coffee and tea shops per capita,” 

says Jill Gonzalez, an analyst with 

WalletHub. Portland boasts the 

fifth largest number of food 

markets and agriculture 

programs supported by 

the community. Another 

factor in the results 

was the number 

of employees 

in agricultural 

activities. That’s 

something 

Gonzalez notes 

can be improved in 

many cities. “Local 

authorities could 

support agriculture 

more and maybe 

even offer incentives 

to those who wish 

to go into farming 

or similar activities,” 

Gonzalez says.

THE GOLDILOCKS 

GREENHOUSE 

Optimizing 

GREENHOUSE CLIMATE 

by Monica Mansfield 

30 


When dialing in the climate in your 

greenhouse, think about Goldilocks. 

The temperature shouldn’t be too hot 

or too cold, the air shouldn’t be too 

moist or too dry, and the air shouldn’t 

be too stagnant or too breezy. Here’s 

how to get everything just right. 

Greenhouses are an excellent way to extend your 

growing season. They allow you to enjoy a warm 

oasis and eat fresh vegetables throughout the winter. 

However, if your greenhouse’s climate is not dialed in, 

you’ll have nothing more than a hot house full of shriveled 

plants with moisture dripping from the walls. When 

growing in a greenhouse, you take on Mother Nature’s job 

of creating the correct temperature, humidity, and air flow. 

Optimizing the climate in your greenhouse is essential, 

and there are many options and techniques to help you 

create this ideal environment. 

Temperature 

Greenhouses capture heat efficiently, even in the cold 

winter months. Your goal is to keep the temperature in the 

proper range for growing. In the summer, you’ll want to 

maintain your daytime temperature at about 75-85˚F and 

nighttime temperature at about 60-75˚F. In the winter, keep 

temperatures between 60-70˚F during the day and as low 

as 45-50˚F at night. The exact temperatures you maintain 

depend on the crops you grow and their preferences. 

Many factors influence the temperature in your greenhouse, 

including light, outside temperatures, and air flow. 

Four methods commonly used for cooling your greenhouse 

are shading, evaporative cooling, fogging systems, 

and thermal mass reservoirs. 

While shading is effective at reducing temperature, it 

also reduces the amount of light reaching your plants by 

50-60 per cent, which can inhibit growth rates. Sometimes, 

however, this trade-off is necessary to ensure your plants’ 

survival. To create shading, you can purchase shade 

cloth, paint-on materials, or adhesive compounds that 

can be applied directly to the glass for a more permanent 

solution. There are also roll-up screens made of wood, 

aluminum, vinyl, or plastic that come with pulley and 

rope systems to allow for adjustment based on light and 

outside temperature. You can grow trees and plants next 

to the greenhouse as a source of shade too. You can even 

grow trees or trellis grapes inside your greenhouse to 

supply shade to other plants. The large size of the grape 

leaves have the additional benefit of acting as a natural 

evaporative cooling system. 


“THE EXACT TEMPERATURES 

YOU MAINTAIN DEPEND 

ON THE CROPS YOU GROW 

AND THEIR PREFERENCES.” 

Evaporative cooling systems, also 

known as swamp coolers, turn hot 

air into a cool breeze by passing air 

through a soaked screen, pad, or spray 

of water. These systems are most effective 

in environments with low humidity 

as they add moisture to the air. 

Fogging and misting systems are also 

often used to cool greenhouses. These 

two systems are similar in that they 

both spray water to cool the air. The 

main difference being the size of the 

water droplets. Foggers create a very 

fine mist, while misters spray larger 

water droplets. These systems can be 

put on a controller to spray water when 

temperatures get too high. While effective, 

the main drawbacks to these types 

of systems are excess humidity causing 

fungal issues within the greenhouse 

and clogged emitters from water with 

high mineral content. 

You can also control temperature by 

keeping a black reservoir filled with 

water in your greenhouse. During 

the day, the water will absorb heat. 

When it cools down at night, heat is 

released and warms up the greenhouse. 

This is the principle of thermal 

mass at work. You can even put your 

tank to good use and grow fish while 

you’re at it. As a rule of thumb, fill your 

reservoir with two to three gallons of 

water per square foot of greenhouse 

space. Finally, if you need to increase 

temperatures in the winter, you can 

use heaters or even wood stoves. 

Ventilation and Air Flow 

Air flow is essential for temperature 

control and fresh air exchange. Without 

fresh air, there will not be enough carbon 

dioxide for photosynthesis unless you 

install a CO 2 generator. Even with a 

generator, you’ll need fans to move air 

within the greenhouse to help prevent 

fungal disease. 

Vents, exhaust fans, and oscillating 

fans can be used for fresh air exchange 

and circulation. You can also install 

roof vents that need to be opened and 

closed throughout the day depending 

on the temperature. Roof vents are often 

operated by hand, but you can automate 

them with a thermostat controller to 

eliminate the manual work. 

Exhaust fans can also be set on a timer 

so air is exchanged as often as once per 

minute. If it is cold outside, you will want 

to exchange the air less often, about a 

few times per hour. You can also hook 

your fans up to a thermostat, so air is 

exchanged when temperatures start 

to rise. Mount these fans high on the 

end walls and make sure they have a 

protective hood so that rain is not blown 

into the greenhouse. 

Ceiling fans or oscillating fans keep 

air circulating within the greenhouse. 

This will control humidity levels and 

strengthen your plants’ stems, just as 

the wind strengthens plants outdoors. 

Finally, if you are going low-tech, you 

can install screened doors on the ends 

of your greenhouse to create cross-ventilation 

and prevent stagnant air. 

32 


“CONTROLLING YOUR TEMPERATURE 

WILL ALSO HELP TO MANAGE MOISTURE 

LEVELS AS HEAT DRIES UP MOISTURE.” 

Humidity 

Humidity levels should be maintained between 70 and 85 per cent. 

When levels begin reaching 90 per cent and higher, growth slows, 

fungal diseases start to occur, and early bolting becomes 

a problem. Keep in mind it can be a challenge to measure 

humidity levels when air is constantly circulating. Placing 

multiple hygrometers around your greenhouse can help you 

get a more accurate reading. 

If humidity gets too high, you can add a dehumidifier to dry 

it out. You might also try pruning your plants. Leaves perform 

a process called transpiration in which they release moisture 

into the air from pores on their surface, so reducing the 

foliage should help reduce humidity levels. Proper ventilation 

and air circulation are also important keys to managing 

humidity levels in a greenhouse. 

So, open doors or vents to reduce 

humidity. Controlling your 

temperature will also help to 

manage moisture levels as heat dries up moisture. 

If you live in an arid environment and need to increase 

humidity, you can do this by spraying the floor with 

water or installing a misting system. 

Greenhouses can make a wonderful addition to your 

garden as long as they are managed properly. When you 

control your temperature, air circulation, and humidity, 

you can take advantage of extended growing seasons 

and eat fresh year-round.

UNDERSTANDING 

HOW 

s t 

UPTAKE WATER 

AND NUTRIENTS 

by Chris Bond 

Roots play an integral part in plant survival, whether it’s as an 

anchor or providing life-sustaining water and nutrients. Chris 

Bond explores just how roots do their job to keep plants alive. 

36 


most folks know what plant roots are and have a vague 

notion of some of the basic functions they perform. Of 

course, roots offer an anchorage system to keep plants in 

place, they store food for the plant in the forms of sugars, 

starches, and proteins, and roots send water and nutrients 

up into the plant. Root systems also play a role in vegetative 

reproduction in some plants. But not everyone knows just 

how the root system does these amazing things — all without 

anyone ever really seeing them in action. 

Root Anatomy 

There are two primary types of root systems — taproot systems 

and fibrous root systems. Both serve nearly identical purposes 

but in different ways. Plants with their respective root systems 

likely evolved based on the conditions of the native soil where 

they thrived, or as an adaptation to the types of roots that 

supported competing plants. Through site-specific evolution 

and human intervention, it is quite probable that in any 

typical landscape you will find plants with both kinds of roots 

growing in proximity to each other. 

p n a 

l ts 

with their respective root systems 

likely evolved based on the conditions 

of the native soil where they thrived, or 

as an adaptation to the types of roots 

that supported competing plants.” 

In taproot plants, the first root or proto-root that develops from 

the germinating seed is called the radicle. This type of root 

system is commonly found on most conifers, dicots, and seedbearing 

plants. It consists of a predominant root that forms 

from the radicle and grows downward. Other less dominant 

root branches will form off this tap root. Monocots primarily 

develop fibrous root systems, though there are exceptions. 

Fibrous roots are a dense mat of similarly-sized roots that do 

not venture as far away from the shoot of the plant. The radicle 

in monocots does not stick around for long; the first root that 

develops and holds the seed in place is aborted and replaced 

by others shortly thereafter, starting the process of developing 

the robust stitchwork of the fibrous root system. 

To peel back a further layer of roots and how they work, let’s 

start at the bottom. The end or tip of the root (on a taproot) is 

protected by a structure called the root cap. The root cap is a 

mass of hardened cells that are the tip of the spear, driving 

the root downward, protecting the layers behind it. Think of 

it as the nose of a space shuttle that can take the brunt of the 

resistance upon re-entry into the atmosphere. 


on c e 

Behind the root cap is the cortex, which makes up the bulk of 

the rest of the root. The cortex is loosely packed with cells and 

empty space, both of which store water and allow it to flow 

into the xylem vessels, sending water and dissolved nutrients 

to the above-ground shoot systems. Roots lack openings such 

as the stomata found in leaves. Rather, roots are covered in 

thin-walled cells, known as parenchyma cells, which act as a 

water-absorbing membrane. These are primarily found in the 

cortex of the root. This entire outer wall of the cortex is known 

as the epiblema and the main conduit for this transport at the 

center of the cortex is known as the endodermis. Unlike the 

rest of the cortex, the cells in the endodermis are more tightly 

arranged so water does not escape back into the cortex but 

can be sent on its merry way upwards through passage cells. 

However, this does not happen until the water and nutrients 

have passed the root system’s smell test. To that end, the 

endodermis is a plant guardian. If the plant has inadvertently 

absorbed any toxic material, the endodermis filters it out and 

rejects it. A waxy barrier known as the Casparian strip is the 

gatekeeper at play here. Proteins within the cells allow for 

the good compounds and molecules to pass, while toxins are 

weeded out and removed. 

Root hairs are an extension of the endodermis. These fine, 

long, and narrow projections grow out from mature roots, 

helping increase a root system’s ability to absorb moisture 

and nutrients by increasing the root system’s surface area, 

which increases contact between roots and soil. 

The stele, pericycle, conjunctive tissue, and vascular bundles 

round out some of the lineup that make up the typical root. 

If you really, really want to know more about the intricate 

functions of roots, or have a severe case of insomnia, look up 

“histogen theory” and/or “Quiescent Center.” For our purposes 

here, these go way beyond the realm of useful knowledge for 

the layman horticulturist, this author included. 

inside the roots or root cells, water 

and dissolved nutrients travel through 

different root pathways in one of two 

ways — either symplastic movement 

or apoplastic movement.” 

The Secret World of Roots 

Root systems are a network of connected botanical appendages 

whose entire mass can sometimes dwarf the aboveground 

portion of the plant it is supporting. It takes a lot of 

work behind the scenes to feed and care for all the flowers, 

fruits, and leaves getting most of the accolades. They don’t, 

however, work alone. The root (mostly below ground) and 

shoot (mostly above ground) systems work in unison in a 

positive feedback loop. Though an oversimplification of the 

process, it’s safe to say the photosynthesis work the leaves 

and greens do sends nutrients below to the root system, which 

is then able to expand and grow, sending more food and water 

upward so more leaves can be produced. Then more photosynthesis 

can occur, and more roots can develop and so on. 

Roots are constantly attracting and transporting water and 

dissolved nutrients from the medium they are in. Deep down 

in the root cells, a pressure builds. This root pressure creates 

a siphon-like action which forces water and nutrients up into 

the above-ground portions of the plant while water and nutrients 

from the surrounding soil are drawn into the root. This 

is due to the higher concentration of nutrients and minerals 

inside the root cells than in the soil environment around the 

root system. In addition to this force, moisture from the soil 

is continually being absorbed into the roots by the negative 

water potential within the root cells.

as 85 per cent of plants may 

owe all or some of their nutrient 

uptake capacity to mycorrhizae.” 

Symplastic vs Apoplastic Movement 

of Water and Nutrients in Roots 

Once inside the roots or root cells, water and dissolved 

nutrients travel through different root pathways in one of 

two ways — either symplastic movement or apoplastic 

movement. Most water and nutrients move through the 

roots via apoplastic movement. When this happens, 

water does not actually enter the cells, but travels 

through the passages between cells. Think of this as 

a hallway connecting bedrooms. This is easier than 

traveling by symplasticity. With symplastic movement, 

water and nutrients must cross over a cell membrane to 

enter into the cytoplasm, a gelatinous material inside the 

cell. Water and nutrients must then travel upwards by 

moving through the cell walls. Think of this as gaining 

access to bedrooms through the adjoining walls instead 

of taking the hallway. 

To recap the process of water and 

nutrient uptake, we can reduce it to 

four basic steps: 

• Step 1: Water and dissolved 

nutrients enter the roots through 

the root hairs by the process of 

osmosis or root force. 


nutrients then cross over the root 

cortex either through symplastic 

or apoplastic movements. 


nutrients enter the xylem. 


nutrients are sent up into the 

plant stem in the transpiration 

stream to deliver needed nutrition 

to all the shoots of the plant. 

These processes will go on so 

long as the plant is alive, and 

water and nutrients can be found 

in the soil. Periods of drought will 

slow down these actions and, 

in some cases, encourage root 

growth as plants seek deeper 

sources of water and nutrition. 

Mycorrhizae: Roots’ Fungal Friend 

Worthy of inclusion, though not a component of root anatomy or 

function proper, is mycorrhizae. This lauded beneficial fungus 

attaches itself to plant roots in a symbiotic embrace that can 

exponentially increase the reach of any particular root system. 

As many as 85 per cent of plants may owe all or some of their 

nutrient uptake capacity to mycorrhizae. The fungus not only 

gets fed while attaching itself to root systems, but acts as a 

force multiplier by increasing the reach of plant roots and the 

surface area of the root system. The hyphae, or tentacles of 

the fungus, are much smaller than even the root hairs and can 

therefore mine into much smaller crevices in search of nutrients. 

In addition to the basic and more complex functions described 

earlier, roots also serve to aerate the soil they are anchored in 

and can pull the plant closer to the dirt for protection from the 

elements. All of these and more are functions of roots in the care 

and feeding of the shoots. 


y Eric Hopper 

enzymes 

IN THE GARDEN 

Enzymes play a major role in plant health as they 

can increase nutrient uptake and help protect 

roots from pathogens. Eric Hopper explains why 

these tiny catalysts work so well in the garden. 

catalyst is defined as a substance that increases the 

A rate of a chemical reaction without undergoing any 

permanent chemical change itself. One group of catalysts 

is found in every garden and provides countless benefits to 

plants. These catalysts are enzymes. Enzymes are highly 

selective catalysts made up of amino acids, proteins, or 

RNA (ribonucleic acid). Enzymes are biological molecules 

responsible for numerous chemical reactions which help 

to sustain all life. They differ from other catalysts in their 

selective nature as enzymes only react with their specific, 

predetermined substrate. The role an enzyme plays in 

these reactions is unique because the enzyme itself is not 

responsible for the reaction, but rather, the speed at which it 

occurs. Essentially, enzymes become a biological regulatory 

system for many of the chemical reactions that affect plant 

life and are an important connection between minerals, 

microbes, and biological creatures. 

40 


Enzyme Reactions are Specific 

Much like a puzzle piece, enzymes take on a certain shape to 

ensure only particular reactions will occur. The place on the 

enzyme where the reaction occurs is called the active site. This 

active site is like a keyhole and will only bind to a specific 

mineral or substrate that fits perfectly. The enzyme remains 

unchanged throughout the entire reaction process. After the 

reaction has occurred and the resulting chemical reactions 

have taken place, the enzyme is ready for a new reaction. 

Increasing the Rate of Reactions 

Like other catalysts, enzymes can increase the rate of 

chemical reactions by lowering the activation energy 

required for the given reaction. In other words, the presence 

of enzymes is what makes particle reaction happen at 

a faster rate. This is one of the reasons why enzyme formulas 

and products that indirectly add enzymes to a grow 

medium have become so popular among horticulturists. By 

supplementing specific enzymes or microorganisms that 

produce enzymes, horticulturists ensure they are maximizing 

the rate at which nutrient absorption can occur while 

helping protect the plants from pathogens. 

“ 

It is the enzymes 

released by 

mycorrhizae that 

help make some of the 

hard-to-capture nutrients — 

such as organic nitrogen, 

phosphorus, and iron — available.” 

Temperature and pH Effect on Enzymes 

Enzymes, and the microorganisms that produce them, do not 

do well in extreme temperature conditions. Extremely hot or 

cold conditions will have a negative effect on enzymes and 

microorganisms. Many prepackaged soils are inoculated with 

beneficial microorganisms in the hopes they will produce 

the enzymes needed to accelerate chemical reactions in the 

soil. However, when a soil is shipped or stored in hot or cold 

conditions, the microorganism population can be negatively 

affected, thus adversely affecting their ability to produce beneficial 

enzymes. Some soil manufacturers have rectified this by 

adding moisture protectants in prepackaged soils to preserve 

the valuable microorganisms and the enzymes they produce. 

The pH of a soil or medium has little effect on the enzymes 

themselves as they can withstand a wide pH range. However, 

the pH of a soil or medium will limit a plant’s ability to uptake 

particular nutrients. Although the enzymes will still be able 

to carry out their functions, the plant itself may not be able to 

reap the rewards because of a pH range falling outside the 

range for nutrient absorption. 

Supplementing Enzymes in the Garden 

A horticulturist can supplement enzymes into a garden 

either directly or indirectly. There are specific enzyme 

formulas containing isolate enzymes. These are an example 

of direct enzyme supplementation. In some cases, an 

enzyme formula is comprised of a single isolated enzyme 

or a combination of multiple enzymes. Most of the isolated 

enzyme formulations are targeted at a plant’s root zone and 

aid in breaking down dead root matter while reducing the 

likelihood of pathogens, such as root rot. 


“ 

Enzymes become a 

biological regulatory 

system for many of the 

chemical reactions 

that affect plant life 

and are an important 

connection between 

minerals, microbes, and 

biological creatures.” 

Beneficial Microorganisms 

Provide Enzymes 

An example of indirect enzyme 

supplementation is the use of beneficial 

microorganisms. Supplementing beneficial 

microorganisms into a medium or nutrient 

solution will indirectly increase the 

number of enzymes since the beneficial 

microorganisms produce the enzymes. 

Mycorrhizae are very popular beneficial 

microorganisms to be supplemented 

in a garden. The enzymes (including 

some hydrolytic enzymes) produced by 

mycorrhizae fungi are what makes them 

such assets to their synergistic plant 

partner. It is the enzymes released by 

mycorrhizae that help make some of the 

hard-to-capture nutrients — such as organic 

nitrogen, phosphorus, and iron — available. 

Trichoderma is another beneficial microorganism 

supplemented by horticulturists. 

As with mycorrhizae, the benefits derived 

are directly linked to the specific enzymes 

released. The enzymes released by trichoderma 

are called chitinase enzymes and 

their main role is to break down chitin. 

Chitin is the main component of fungal 

cell walls, which means the enzymes 

created by trichoderma can help protect a 

plant from pathogenic fungi. In fact, it is 

the chitinase enzymes produced by trichoderma 

that are responsible for trichoderma’s 

reputation in warding off pathogens. 

When pathogenic fungi exist in the 

soil, trichoderma will increase chitinase 

production, which, in turn, will attack the 

pathogen. Many indoor horticulturists are 

adding trichoderma as extra insurance 

against root-borne pathogens. 

Trichoderma also produces cellulase 

enzymes, which break down cellulose. 

Cellulase enzymes can add another level 

of protection for plants. The cellulase 

enzymes can penetrate the cells in the 

plant’s root system, instantly triggering 

the plant’s natural defenses and 

stimulating the plant’s metabolism. No 

real harm is done to the plant and the 

heightened response helps protect the 

plant from other pathogens. 

Whether a horticulturist supplements 

an isolated enzyme formula or the 

microorganisms producing the enzymes, 

the benefits of enzymes in the garden are 

undeniable. Considering nutrient uptake is 

dependent on multiple chemical reactions 

in the soil, and enzymes are the catalyst 

to increase the rate of those reactions, it 

is no wonder so many growers are relying 

on enzyme supplementation. As more is 

discovered about enzymes and how they 

can assist gardeners, the horticultural 

industry is sure to see even more enzymespecific 

additives, fertilizers, and pest 

control products emerge in the future.

Combining Sunlight & Grow Lights: 

Supplemental 

Greenhouse Lighting 

by Kent Gruetzmacher 

Indoor and outdoor growing are no 

longer distinct schools of thought. 

Greenhouse cultivators have 

combined the practices to create 

a new, more cost-effective method 

that uses both sunlight and grow 

lights to power crop production. 

Once considered two distinct schools of thought in 

horticulture, the line between indoor and outdoor 

cultivation is being blurred. Highly sophisticated, 

year-round greenhouses are at the forefront of this 

fusion movement as they utilize the best practices of 

both methodologies in a creative give and take. These 

operations utilize the sun’s energy to power essential 

plant functions while implementing indoor growing 

technologies like light sensors, blackout tarp systems, 

dehumidifiers, and industrial heaters to mimic indoor 

environmental controls in outdoor settings. 

Perhaps the most vital technological application 

in these modern-day greenhouses is that of 

supplemental lighting. In indoor gardening, lighting 

is one of the most important factors dictating the 

outcome of a harvest. However, it is also one of the 

costliest elements of an operation, with an overhead 

of at least $400 per unit for 1,000W double-ended high 

pressure sodium (HPS) lights and $800 per unit for 

comparable light emitting diodes (LEDs). Taken to 

a commercial scale, this overhead can prove quite 

intimidating as it is solely up to these artificial 

light sources to feed every square inch of a massive 

garden canopy. Then there is the astronomical cost of 

running the lights in these large-scale set-ups. Some 

10,000-square-foot warehouse grows have reported 

power bills to the tune of $12,000 monthly. 

44 


However, modern greenhouses use best practices from 

both indoor and outdoor cultivation. When it comes to 

lighting, this means employing a careful balance of 

sunlight and supplemental light. It’s revolutionizing the 

way in which people grow crops outdoors. 

To give us some expert insight into supplemental lighting 

applications for greenhouses, Maximum Yield reached 

out to Brendan Strath, senior solutions director and grow 

ninja for Spectrum King LED, a company that makes fullspectrum 

LED grow lights. Here is what Strath had to say. 

How important has supplemental lighting become in greenhouse 

cultivation and what are its primary benefits? 

Supplemental greenhouse lighting is now an essential 

part of outdoor farming. It allows growers to keep crop 

production going on short winter days and bad weather 

days by providing a consistent light source in the greenhouse. 

Production costs are greatly reduced by combining 

sunlight with supplemental lighting. Each light is not on 

full-power all day (when sunlight is at its strongest) and 

greenhouse lighting grids generally spread lights out 

more than with indoor growing. As such, lights run less, 

and they cover a greater square footage, greatly reducing 

costs per square foot of canopy. 

“ 

Modern greenhouses use best practices 

from both indoor and outdoor cultivation.” 


What would you say is the biggest benefit of supplemental 

lighting in greenhouse growing? 

For me, the use of supplemental lighting in greenhouse 

growing has its largest impact concerning carbon footprints. 

“ 

By 

keeping production costs down through 

greenhouse growing, we can offer fresher 

and healthier food and medicine.” 

Modern greenhouse cultivation with the bonus of supplemental 

lighting truly diversifies horticultural applications outdoors. 

Plus, as Strath mentioned, this form of growing is also economically 

viable and more environmentally friendly. With this sort 

of best practice, technological advancements have allowed 

greenhouse growers to devise cultivation methods that can 

realistically sustain the industry well into the future. Finally, 

novice and expert growers alike can use supplemental lighting 

to produce fresh medicines and crops all year round. 

Using the greatest light source in the world (the sun) for the 

heavy lifting and just supplementing a few hours a day when 

sunlight intensity is low is a much greener way of producing 

crops than with straight indoor growing. Also, with this 

method, you can produce quality crops all year round with 

lower production costs. 

Is the use of supplemental lighting more prominent with growers 

in certain regions of the United States than others? If so, why? 

That’s a great question and one that is often overlooked. Yes, 

at first-glance some regions are better suited for greenhouse 

growing than others. Any geographies with extreme weather 

conditions (a.k.a. cold, wind, snow, etc.) are perfect for greenhouses; 

they offer environmental protections for crops while 

utilizing sunlight. Grows in those regions without consistent 

sun also benefit the most from supplemental lighting. 

However, with a little thought and ingenuity, you can do well 

with greenhouse cultivation just about anywhere on Earth. 

Many see automated greenhouse growing as the “future of the 

industry” because it utilizes controlled environment agriculture 

with the added perk of sunlight. What are your thoughts on this? 

I couldn’t agree more with that statement. Whether it’s medical 

crops or food production, people want healthier choices that 

are also cost effective. By keeping production costs down 

through greenhouse growing, we can offer fresher and healthier 

food and medicine. To me, that’s an obvious no-brainer.

Hard or Soft: 

KNOW YOUR GARDEN 

WATER 

by Bryan Traficante & Wiley Geren 

Not all water is the same and what 

type of water — whether hard or 

soft — is flowing through the pipes in 

your house might be impacting how 

well or poorly your garden is doing. 

o you know what type of water is 

Dflowing through your house and 

hose spigot? If you don’t, it’s easy to 

figure out. Next time you take a shower, 

pay attention to how your skin feels 

afterwards. Do you feel slippery, or do 

you feel squeaky? If you feel slippery, 

then you have soft water. If you feel 

squeaky, then you have hard water. Does 

hard or soft water make a difference to 

your garden plants? As part of a plant’s 

holy trinity – water, sun, soil – you 

need to know what kind of water you 

are using. If you have been having a 

tough time getting anything to grow 

in your garden and have checked your 

soil and sun, then the problem could be 

your water. But what is the difference 

between hard water and soft water? 

HARD WATER 

No, hard water doesn’t mean it’s mixed 

with alcohol. Hard water is comprised 

of dissolved minerals – the majority of 

which are calcium (Ca), magnesium 

(Mg), and lime. Unless you have a water 

softening system, hard water (to varying 

degrees of hardness) is the standard 

type that flows through public and 

private systems. Once again, there is an 

easy way to tell if you have hard water. 

If, over time, white/pink scum builds up 

on your household fixtures (sinks, bathtubs, 

toilets, etc.), then you have hard 

water. Those buildups are caused by the 

minerals slowly collecting. However, 

that does not mean hard water is bad 

for you or your garden. 

“ 

SOFT WATER 

Soft water is treated, or softened, with sodium which 

removes the minerals. That’s why your skin feels slippery 

after showering with soft water and why glassware 

looks cleaner after washing with it. The minerals that 

build up on your skin have been removed, so there’s 

nothing to wipe off. To remove the minerals, water is 

treated with sodium in a system usually set up somewhere 

within your residence. Soft water systems are 

often installed in areas where there is a high amount 

of minerals in the water that may affect the plumbing, 

or simply because some people prefer the taste and 

feel of soft water over hard water. It may not leave 

buildup or residue on your fixtures and skin, but that 

does not mean soft water is good for your garden. 

PROS AND CONS 

FOR GARDENING 

The simple answer: Treated soft water 

has little to offer your garden except 

plant-killing sodium. Although only 

trace amounts of sodium are present 

in soft water, it can build up over 

time in the soil. After enough 

builds up, the sodium causes 

your plants to die of thirst. If 

you are worried this is the 

case now, you should leach 

your soil. This is done by 

watering thoroughly and 

frequently, which basically 

washes away the sodium 

buildup. However, you’ll 

also be washing away some 

nutrients and minerals 

that are vital to your 

garden’s nourishment. 

Treated soft water has little to offer your 

garden except plant-killing sodium.” 

48 


If you leach your soil, make sure you replace 

the mineral/nutrient content afterwards with an 

additive or fertilizer. 

Hard water provides your garden with useful 

mineral content and doesn’t have the excess 

sodium of treated soft water. Calcium and 

Magnesium are vital to a plant’s growth but can 

be harmful in large doses. Too much can cause 

chlorosis – a yellowing of the leaves which is a 

symptom of sickness. To prevent sickness like 

chlorosis, use a raised garden bed that provides 

better drainage. Excess minerals will leach from 

the soil naturally, be rebalanced with 

the minerals in your hard water, and 

your garden will be much happier. 

“Hard water provides your 

garden with useful mineral 

content and doesn’t have 

the excess sodium of 

treated soft water.” 

WHICH SHOULD I USE 

FOR MY GARDEN? 

This is a trick question because the best 

option for your garden isn’t hard water or 

soft water, but rain water. Rain water, while 

technically soft water, lacks the sodium of 

treated water and won’t lead to that excess 

mineral build-up hard water can bring. Rain 

water is friendly to plants and, conveniently, 

can be collected in rain barrels for use in 

your garden. If you don’t want to collect and 

use rain water, the next best option for 

your garden is hard water. 


LIGHT LEAKS 

AND SEALED GROWROOMS 


Light leaks in your sealed growroom can 

be disastrous for some kinds of plants. 

They can also be a sign that more than 

just light is getting in, including pests 

and other environmental variables. 

When planning and setting up indoor gardens, 

growers spend time and money in the creation 

of environments where plant species thrive. For sealed 

growrooms, this process represents a careful balancing 

act between temperature, humidity, light, and CO 2. 

However, once an indoor grow is operational, these 

synthetic environments create challenges for growers 

that are non-existent in the natural world. The reaction 

of indoor plants to light leaks during dark periods (nighttime) 

presents one of these unusual phenomena. 

50 


Pioneer 

Grow Books 

“For the avid grower, 

these books are indispensable.” 

GARDEN CULTURE 

Check out our new website at 

MAMAPUBLISHING.COM

Certain species of plants are subject to photoperiodism, 

in which the varying duration of light cycles between day 

and night cause plants to enter new phases of growth. 

To illustrate, uninterrupted 12-hour periods of darkness 

(nighttime) causes some plant species to start flowering. 

This process occurs when a hormone called photochrome 

reacts to sunlight intensity and durations, directing plants 

towards the different phases of growth. 

“It’s a good idea for cultivators to regularly 

check their growrooms to make sure they are 

100 PER CENT 

DARK DURING THE NIGHTTIME PERIOD.” 

If a sealed growroom is not 100 per cent dark during the 

nighttime period, photoperiodism cycles can be interrupted, 

causing photochrome imbalances as related to specific plant 

processes. These hormonal imbalances can have negative 

and sometimes detrimental effects on an indoor harvest. 

For those looking to avoid issues with light leaks in their 

sealed growrooms, consider the following points: 

Inconsistencies and Stress 

Indoor gardeners should always strive for consistency in 

their growroom environments. Most crops perform best in 

stable environments, and bountiful harvests are the result 

of constant environmental balance — including stable 

lighting intervals — during both vegetative growth and 

flowering. A common misconception amongst indoor growers 

is that light leaks during the vegetative growth phase won’t 

disrupt crop growth. However, any irregularities in lighting 

patterns can stress plants out. Along this line of thought, all 

environmental stressors inhibit essential plant functions, 

such as nutrient uptake, and retard growth. 

Light leaks can also prove troublesome regarding 

photochrome levels in plants, as unexpected or irregular 

doses of light can alter stable hormonal conversion processes. 

During flowering phases, excess light during dark periods can 

push photochrome activity to the point of converting a plant 

back into vegetative growth. 

Hermaphrodites 

One of the most widely known negative side effects of 

growroom light seepage has to do with the transformation 

of female plants into hermaphrodites. For those looking to 

grow seed-free flowering plant varietals, hermaphrodites can 

prove devastating for a crop. This is because male flowers on 

a single plant can pollinate an entire growroom and greatly 

devalue a harvest. 

Expert horticulturists agree that certain plant species 

turn hermaphrodite as a result of environmental 

stressors, and light leaks are notorious for being 

associated with this phenomenon. However, it should be 

noted that the occasional beam of light on a garden from 

a headlamp won’t cause plants to “herm.” While indoor 

growers should strive to avoid any disruptions in regular 

light cycles, it takes rather consistent light exposure to 

force a plant into hermaphrodite growth. These sorts 

of leaks come from constant sources, such as under 

doorways and walls, that occur on a daily basis. 

Light Leaks Mean Other Leaks 

Indoor growers can be assured that if their sealed 

growroom is leaking light, it has issues with other leaks. 

Seasoned cultivators go to great lengths to ensure that 

their sealed gardens are functioning at their best when 

it comes to atmosphere, temperature, and sterility. 

All these contingencies are compromised with an 

improperly sealed growroom. 

If leakage issues arise, growers sacrifice the total 

environmental control that is so essential in sealed 

room growing. With this issue comes potential 

problems with maintaining ideal, static levels of 

temperature, humidity, and CO 2. Moreover, as sealed 

rooms are wholly dependent upon CO 2 injection 

technology, the regular loss of CO 2 to leaks is 

financially burdensome and operationally threatening. 

If light leaks can penetrate the confines of a sealed 

garden, so can airborne pathogens. As such, it is 

virtually impossible to fully sterilize an indoor grow if 

bugs and spores (of powdery mildew and botrytis) can 

continuously access the grow space via leaks. 

52 


Locating Light Leaks 

Many indoor growers don’t know that their rooms have 

light leaks until it is too late, and the problem expresses 

itself by way of hermaphrodites and seeded flowers. As 

a result, it’s a good idea for cultivators to regularly check 

their growrooms to make sure they are 100 per cent dark 

during the nighttime period. 

To inspect an indoor garden for light leaks, it’s best to 

enter the grow with a green light when the primary lights 

are off. Once situated in the garden, turn off the green 

light and sit still for a while to let your eyes adjust to the 

blackness. At this point, it should be easy to canvass the 

walls and ceilings of the room and discern any potential 

points of light leak trouble. Also, this inspection process 

should be done during various parts of the day, as 

different angles of sunlight outside can cause light leaks 

during isolated time frames. 

Gardeners should also be advised that control panels 

on grow equipment, such as atmospheric controllers 

and AC units, often give off light. This light is usually 

red or green and is residual from the digital readout. 

As such, it is recommended that growers cover up 

these light sources with electrical tape or some sort of 

removable opaque material. 

“Most crops 

PERFORM 

BEST 

IN STABLE 

ENVIRONMENTS.” 

Compared to any other form of controlled environment 

agriculture, sealed-room growing provides the most mastery 

over environmental factors. However, these growrooms 

present novel challenges of their own, as seen with the issues 

surrounding light leaks. For the conscientious gardener, 

regular inspections of one’s garden should alleviate any light 

leak problems. All things considered, this knowledge will 

provide a better platform for troubleshooting on the macrolevel 

moving forward. 


AUTOMATIO 

for outdoor soil gardens 

54 


While automation is a huge 

part of indoor growing, 

outdoor soil cultivators 

can also take advantage 

of technologies like 

controllers and fertigation 

injectors to cut down on 

labor and overall costs. 


N OPTIONS 

Indoor and outdoor horticulturists 

enjoy certain perks of their respective 

practices, and these perks are generally 

interrelated with gardening labor 

and work environment. For indoor 

growers, access to conveniences such 

as electricity allows for the use of 

technology related to environmental 

controls, lighting systems, and 

irrigation setups. These workplace 

bonuses generally make the day-today 

routine of the indoor grower more 

enjoyable, as they lighten the workload 

and allow for the precise monitoring 

of the indoor garden atmosphere. 

Conversely, outdoor gardeners grow 

their crops under the expanses of blue 

summer skies, breathing fresh air with 

their hands in the dirt. For outdoor 

growers practicing organic cultivation, 

these natural environments blend 

seamlessly with a deep appreciation for 

the living biologics of soil growing. 

Looking at the perks of both indoor 

and outdoor growing, one must ask: 

Can’t I enjoy the benefits of both? While 

it goes without saying that indoor 

cultivators can’t enjoy the freshness of 

the outdoors, who says outdoor growers 

can’t make their lives easier with some 

technological advancements? With 

that, Maximum Yield decided to look 

into automation options for outdoor soil 

gardens to ensure that, over the long 

summer, outdoor gardeners have ample 

time to bask in the rays of the summer 

sun. For those outdoor enthusiasts 

looking for a technological boost in 

their operations, here are a few options. 


“ 

CONTROLLERS 

ARE THE 

ESSENTIAL 

ELEMENT 

Controllers 

Advancements in digital control 

technology for controlled environment 

agriculture have made controllers, or 

“brains,” an essential tool in modern 

gardening, both indoors and outdoors. 

For indoor growing, controllers have 

taken the thinking process out of 

mundane, yet easy to forget, chores like 

setting lighting timers and regulating 

temperatures. Similarly, for tech savvy 

outdoor growers, the fluidity and easeof-use 

of these smart-products is too 

tough to resist. While most smart indoor 

garden technology sets forth to regulate 

ambient environments, automated 

systems for outdoor growing focus 

solely on irrigation. 

Controllers are the essential element 

in transitioning an outdoor soil garden 

from a hand watering or drip system 

to a smart irrigation program. Utilizing 

cutting-edge computer technology in 

conjunction with touch screen displays, 

controllers send precisely dictated 

electronic signals to components in 

the physical figurations of irrigation 

infrastructures (see next section). With 

electronic integration, these smart 

controls regulate valves relating to 

both nutrient and water dispersal in 

the macro-irrigation system. The more 

sophisticated of these controllers 

can be programmed to mix up to 20 

different fertilizer feeding regiments, 

simultaneously, for a single garden. 

The ease-of-use for smart irrigation 

controllers is tied to both their 

technological perks and practical 

applications. Generally, 

in transitioning an outdoor soil 

garden from a hand watering or drip 

system to a smart irrigation program.” 

controls are the most 

beneficial for outdoor 

cultivators as relating to 

timing and consistency, 

they can be set on 

digital timers or light 

sensors for automated 

irrigation on a daily 

basis. As 

many plant 

species thrive 

on consistent 

watering and 

environments, 

the precision 

of controllers makes them a serious 

value-add for outdoor commercial 

operations. Also, many controllers 

feature “cloud-based capabilities,” 

in which a grower can monitor and 

change irrigation and nutrient levels 

from their smart phones or computers. 

As such — and if implemented 

correctly, outdoor soil growers can alter 

irrigation practices from afar — this 

perk is particularly notable concerning 

changing weather and temperature 

patterns. All things considered, 

controllers can add efficiency and 

stability in outdoor gardening practices 

that are notorious for getting off 

schedule due to human error. 

It’s worth noting outdoor growers 

must be diligent in taking care of 

controllers, as sun, dirt, and dust can 

easily damage these somewhat fragile 

pieces of technology. Controllers 

should be well-mounted in a protected, 

low-traffic area, ideally within a metal 

or wooden box. 

Fertigation Injectors 

For both indoor and outdoor growers, 

fertigation injection systems have 

become a staple of ease and efficiency. 

Traditionally, water-based fertilization 

processes have been hinged on the 

labor-intensive practice of manually 

mixing nutrients in reservoirs or 

holding tanks. For commercial sized 

operations, this demanding and 

tedious chore often involves the 

mixing of thousands of gallons of 

water at a time, multiple times a day. 

However, with some ingenuity and 

careful planning, the engineers behind 

fertigation injectors have developed 

a product which nearly eliminates 

the painstaking chore of hand mixing 

water-soluble fertilizers.

As discussed in the previous section, 

smart controllers can be implemented 

in conjunction with fertigation injectors, 

creating a highly efficient and precise 

system for outdoor soil irrigation. In 

layman’s terms, the controller dictates 

the operations of several pressurized 

valve systems that are fed from 

separate containers of nutrients. The 

controller also regulates water pressure 

from the primary water source. When 

the irrigation process begins, water 

flows through a pipe that is integrated 

with the nutrient valve system, then the 

fertigation injector releases nutrients 

into the water flow in conjunction with 

specific levels of water pressure. When 

operating and balanced correctly, the 

fertigation and controller combination 

delivers precisely measured, nutrientrich 

water into soil containers — with 

little human effort. 

For good reason, outdoor commercial 

cultivators have come to cherish the 

ease-of-use of fertigation injectors. For 

outdoor growers committed to a six- to 

seven-month growing season, automation 

options like fertigation literally 

eliminate hundreds of hours of unnecessary 

labor in manual nutrient mixing. 

The precision of fertigation is entirely 

unmatched by human effort; top-ofthe-line 

injectors disperse carefully 

controlled amounts of nutrients down to 

five milliliters per injection 

For economically and 

environmentally conscious cultivators, 

the precision afforded by fertigation 

injectors brings significant savings on 

both water and fertilizer use compared 

to traditional hand-mixing methods. 

Because hand mixing nutrients in 

large reservoirs always leads to an 

excess of leftover water that generally 

cannot be reused — this problem 

is non-existent with the strict 

controls of fertigation. 

Drip Systems 

While drip watering components don’t 

necessarily fall into the automation 

category, they are an essential element 

in any smart irrigation plan for the 

outdoors, especially concerning organic 

growing. With that, the controller and 

fertigation injector combination feed 

nutrient-rich water through hoses or 

pipes, and finally into soft-plastic tubes 

that should be embedded deep in the 

soil of each garden container. 

Since outdoor growing containers 

are generally far larger in size than 

their indoor counterparts (Smart Pots 

can range up to 1,000 gallons in size), 

top drip systems work inefficiently for 

outdoor growing. Concentrated drips 

of water in such large containers leave 

a clear majority the soil unirrigated, 

leading to several serious problems. 

Therefore, to effectively deliver water 

and nutrients, automated outdoor 

irrigation systems must utilize long 

lengths of perforated irrigation tubing 

that is coiled around inside the 

soil-filled container. With this method, 

fertilization will be accomplished in a 

uniform fashion, and organic soils 

will retain the requisite moisture 

content to maintain the integrity of their 

biological communities. 

In utilizing some of the automation 

perks from indoor gardening, and 

adding some necessary tweaks, outdoor 

cultivators can enjoy the benefits of 

cutting-edge irrigation technology. For 

commercial-sized operations, the benefits 

of smart equipment like controllers 

and fertigation injectors far outweigh 

financial costs. Looking forward, one 

can only assume outdoor growers will 

continue to combine their passions for 

soil growing with the modern gardening 

technologies, making for a practice that 

utilizes the best of both worlds. 

“ 

FOR ECONOMICALLY 

AND ENVIRONMENTALLY 

CONSCIOUS CULTIVATORS, 

the precision afforded by 

fertigation injectors brings 

significant savings on both water 

and fertilizer use compared to 

traditional hand-mixing methods.”

herb garden 

by Becky Evans 

While home (and garden) ownership these days is 

unattainable for many, it doesn’t mean apartment dwellers 

can’t reap some gardening rewards. Becky Evans explains 

how to create an indoor herb garden that will satisfy your 

green thumb and complement your meals. 

Let’s face it. A lot of people these days live in apartments, and the dream 

of owning a house with a garden is only attainable for the lucky few. 

However, with some clever interior design tricks, you can create a garden 

space within your kitchen and reap the benefits of fresh, 

healthy herbs grown in the comfort of your apartment. 

Choose an Optimal Location 

The obvious location for your indoor herb garden 

is on the inside window sill. So long as you can 

nourish your herbs with a minimum of four 

hours of direct sunlight daily, this is the best 

option. Getting this essential sunlight can be 

easier said than done, and apartments on 

lower floors might struggle to get enough 

light. If you are lucky enough to get direct 

sunlight, don’t forget to turn your herb pots 

every three days so they grow evenly. 

If you can’t find enough natural light 

for your plants to flourish, you will need 

to consider a grow light, which can be 

purchased online or at a garden center. 

Place the lamp beside your herbs to give 

them between four to six hours of light a day. 

Three Essential Herbs to Plant 

You want a variety of herbs that will add a 

special touch to meals that you regularly cook, 

and you want herbs that look impressive too. 

60 


“You can create a garden space 

within your kitchen and reap the 

benefits of fresh, Healthy herbs.” 

BASIL—No self-respecting herb garden can grow proud without basil. This 

sweet-tasting, popular herb has an anise, clove-esque aroma. Use it fresh or dried 

in a wide selection of different meals, from a classic Bolognese to a tasty accompaniment 

with a salmon dish. Basil comes jam-packed with vitamins A, K, 

and C, as well as magnesium, iron, and calcium. 

CHIVE—Similar to onions and garlic, growing chives can ward off insect 

pests like mosquitos from your herb garden. What’s more, chives are full 

of bacteria-fighting antibiotics from their high sulfur content. Chives 

also are a natural anti-inflammatory; they’re nature’s ibuprofen. 

CORIANDER—Regarded as an essential in any herb garden, coriander 

(also commonly known as cilantro) punches above its weight. It is high 

in vitamin C and can aid digestion, relieve inflammation, and balance 

blood sugar levels. Its potent flavor and smell makes a perfect seasoning 

for meats, salsas, and oriental dishes. Also, coriander seeds add 

warmth and spice to chicken, vegetables, and soups. 

Choose and Prepare Pots 

It is essential that you get pots that can drain well. Start by 

filling your pot with a potting mix, leaving a half inch of soil 

between the top of the pot and the potting mix. You can find a 

lot of funky vintage pots online or you could upcycle some old 

furniture. Once you have your pots, you can plant your herb 

seeds and water them thoroughly. Allow them to drain until 

they stop dripping, then place the pots on the windowsill with 

a tray underneath to catch any last drips of water. 

Kitchen Garden Maintenance 

Herbs are a sensitive bunch and they will need tender loving 

care to survive. A snip here and a prune there is essential 

for a bigger harvest and sturdier herbs. Remember to cut 

any new growth a minimum of once per week and when 

new stems grow out. 

Turn your pots at regular intervals, especially if they 

are directly in front of a sunny window. This will make 

sure that they grow evenly and prevents the side in the 

shade from undue neglect. 

Of the most important things to remember, watering is 

a priority. Place small gravel in a tray and put your herb 

pots on the tray. Fill the tray up to the top with water 

once per week. Your herbs will absorb what they need 

from the bottom of the pots. 

Keep an eye on your herb garden. In time, you will notice 

when your herbs are dehydrated or need more light as they 

change color and appearance. Once they are thriving, you 

can take pride in cutting a few herbs from your windowsill to 

complement your favorite meals.

“ Being a grower and thinking like a grower, 

I CREATED PRODUCTS OUT OF NECESSITY.” 

How did you get into this industry? 

HYDROPONIC RESEARCH: 

Growing up in Escondido, CA in a humble home that sat 

on a plot of highly fertile land, (Hydroponic Research 

founder) Christopher Larose began developing an interest 

in agriculture at a young age. His father taught him how 

to care for a variety of plants such as peppers, oranges, 

peaches, tomatoes, lettuce, roses, avocados, pears, and 

kiwis. As a young adult, he became fascinated with 

botany and soil chemistry and began experimenting with 

hydroponic gardening, absorbing as much information as 

possible from interactions with other hydroponic farmers, 

books, and other resources. Frustrated by the absence of 

an all-phase hydroponic nutrient that could provide all 

necessary nutrients throughout the life cycle of a plant, he 

set out to generate an easy-to-use, yet powerful formula that 

complemented both tap water and reverse osmosis (RO) 

water sources. Encouraged by growers who were astounded 

by the performance of his formula, Larose finally decided 

to make his premium hydroponic nutrient and outstanding 

solution available to hydroponic farmers throughout the 

United States. In 2010, he set up a laboratory and warehouse 

space in San Diego and began conducting experiments 

to perfect Hydroponic Research’s VEG+BLOOM formula. 

Sharing it and demonstrating it among other hydroponic 

gardeners, the formula reached a stage of maturity in 2011 and 

became available to interested buyers. Realizing that there 

is still room for growth in hydroponic gardening, Hydroponic 

Research continues to innovate and experiment with new 

hydroponic solutions in their San Diego laboratories. 

SOLSTICE GARDEN SUPPLY: 

In 2014, Zack Vondrak (formerly of 

Aptus, Advanced) met Larose at a 

meeting in San Diego and realized 

the potential for a comprehensive 

powder nutrient line. He asked 

Patrick Kanzler (the former GM of 

Humboldt Wholesale, a.k.a. House 

and Garden) to help him with the venture. After testing the 

nutrient line personally, Kanzler recognized the revolutionary 

technology present in the formulas. With their combined experience 

in sales, marketing, and distribution, they made the 

perfect team to bring VEG+BLOOM to market on a large scale. 

What were the start-up years like? 


Hard. Being a grower and thinking like a grower, I created 

products out of necessity. I needed simple and complete — less 

guessing and more growing. It was easy to overlook that store 

owners selling liquids were less interested in one product not 

require multiple things to work. 

What were some of your struggles as you started the 

business? How did you overcome them? 

From being nobody in this industry and becoming somebody. 

It was a unique obstacle. Scaling up and learning to be a 

manufacturer and what is required to refine a product and 

maintain consistency. I had to develop relationships ranging 

from pharmaceutical suppliers, food ingredient distributors, 

and industrial engineers. It was a lot of work. Many companies 

are formed from capitalist concerns. We were able to grow as a 

company from the need to develop tools we use ourselves. 


“ WE HAVE THE BEST SALES 

REPS IN THE INDUSTRY. 

We hand-picked them and waited 

for the right guys to join us.” 

How did you gain market share and recognition? 

We gained market share in the early days by sharing it 

with growers and discussing the formula on forums and 

with local growers. As independent thinkers discovered 

our products, we developed a cult following. This became 

the seed that grew into our present-day customer base. 


In 2015 it was really tough to bring a relatively new nutrient 

line to market. We approached our contacts at many stores 

to help us launch but we were met with indifference. No one 

wanted a product they hadn’t heard of and customers didn’t 

ask for. While the industry relationships are still valuable, 

we understood that we needed to create a demand for the 

product first. Only then would stores choose to stock the line. 

We came up with an innovative strategy for 2015. We 

would openly market toward cannabis growers. We 

recognized the growing popularity of Instagram among 

growers and started posting pictures of cannabis 

grown with the product. We leveraged the existing cult 

following and began co-branding with growers. At that 

time, growers were only starting to think about branding 

and marketing themselves. We worked together in a 

symbiotic way to promote these talented guys and also 

the VEG+BLOOM line. Convincing people to give up their 

liquid nutrients was difficult. But when they could see 

photos of respected growers producing top quality flowers, 

it was impossible to ignore. Once we overcame the 

question of “Does it work?,” the product started moving. 

With the incredible price point of a powder, all inclusive, 

one-part base nutrient, growers could no longer ignore it. 

What did you first produce? 

Small-batch powder fertilizers 

How has your company expanded over the years? 


We started off in a small, cold brick building in downtown 

San Diego without a sink. Constantly fighting the city 

for permits to occupy multiple warehouse spaces. Doing 

everything solo to having two shifts of employees covering 

different processes. Creating and developing operating 

procedures where there is no blueprint. Seeing all that 

work get recognized and appreciated.

“ 

HYDROPONIC RESEARCH CONTINUES TO INNOVATE 

and experiment with new hydroponic solutions in their San Diego laboratories.” 


In 2015 we started working from our cell phones and home 

offices. Soon we hired our first employee and moved into a 

trailer in Zack’s backyard, then a small warehouse in San 

Diego that we quickly outgrew. We are still in San Diego just a 

few blocks from Hydroponic Research. We can walk between 

offices for meetings and we save a lot on inbound freight. 

Where do you distribute? 

Worldwide. 

What is your current product line? 

• One Part Base: DIRTY, HD, RO/SOFT, and TAP HARD. 

• Two part Base for Fertigation systems: DOS A and B. 

• Additives: SHINE (bloom stimulant), +LIFE (probiotics), 

PUSH (Calcium Silicate and Kelp foliar spray), and 

STACKSWELL (cal mag with added technology). 

How many people now work for the company? 

We have 20+ employees combined between the companies. 

What makes your employees so awesome? 

We have the best sales reps in the industry. We handpicked 

them and waited for the right guys to join us. Also, 

our support staff is on top of it. Our sister-team office staff 

makes sure everything is done right and our warehouse 

crew (all awesome musicians) work hard everyday to 

ensure orders get out on time. 

What are your company’s strengths? 

Roots in the industry, amazing easy to use products, 

attention to detail, customer service, passion, and we’re 

always striving to be better. 

What are some of your proudest moments? 

Making our first-ever sale to a store and growers using 

our products winning cups. 

What significant things have you learned so far 

about the industry? 


Teamwork makes the dream work. 


“ IT’S A LOT OF WORK building, 

growing, and maintaining relationships.” 

What have you learned about starting 

and growing a company? 

Managing people is an art form. There are ups and downs; 

it’s how you problem solve and bounce back. 

What words of wisdom can you share 

about the business, the industry, or the future 

of the industry? 

People that have been doing this for a long time should 

stick together and help each other. 

Share your favorite story from a day on the job. 

Saw the former president of Mexico at Canna Con Seattle! 

How does your team bond? 

We are like family! Everyone genuinely cares to be here 

and is an equal part of the team. Since we have some musicians 

on the team, we have a jam room in the warehouse 

and the guys get together and play music. We make a point 

to all get together regularly and have fun outside of work, 

as well as enjoying the work we do while we are doing it! 

What significant things have you learned 

so far about the industry? 


The amount of greed in it. The different reasons people 

or companies are a part of it. That it is a constantly 

changing landscape. 

What have you learned about starting and growing 

a company? 

Providing something for people across the world is a beast. 

The reality it takes to make it happen. It’s a lot of work 

building, growing, and maintaining relationships. 

What makes your employees so awesome? 

See for yourself @hydroponicresearch on Instagram. We 

care about each other. We celebrate each other. We take 

time to get together outside of company walls to get away 

from the daily hustle of things and hang out.

FACTS ON 

THE GOLGI APPARATUS 

by Philip McIntosh 

You can’t tell much about it by its name, other than a person 

named Golgi (pronounced gol-gee) had something to do with it.” 

FIRST REPORTED in 1898 by Italian physician and biologist Camillo Golgi, this organelle is 

important in processing proteins into their final configuration and in sending them to their destinations. 

THE GOLGI apparatus is also called the Golgi body, Golgi complex, or just Golgi. 

THE GOLGI receives vesicles budded off from 

the endoplasmic reticulum (ER). These vesicles contain 

proteins requiring further processing before they 

become active. 

THE GOLGI is a “central delivery station.” Proteins 

sent there from the ER are modified, repackaged, and 

delivered to where they are needed inside the cell. 

PROTEINS DESTINED for a role outside 

of the cell are packaged into vesicles by the 

Golgi, which then sends them to fuse with the cell 

membrane to be excreted. 

THE GOLGI apparatus is found only in Eukaryotes 

— organisms whose cells contain nuclei, such as those 

of plants, animals, fungi, and protists. 

ALTHOUGH THE Golgi is a large and distinctive 

organelle, it took the application of the electron 

microscope before it was accepted as a legitimate 

and distinct subcellular structure. 

IN APPEARANCE, the Golgi resembles a series 

of flattened pancake-shaped vesicles, usually located 

near the nucleus, not far from the ER. 

THE INDIVIDUAL small membranous sacs that 

make up the Golgi are called cisternae or dictyosomes. 

IN PLANTS, the Golgi apparatus also plays a 

major role in production of polysaccharides destined 

for incorporation into the cell wall.
