from the editor | toby gorman 

We are taking a new 

perspective on the 

world of modern 

growing, and we look 

forward to bringing 

these stories to you. 

The world of indoor growing is expanding at an incredible rate. No 

longer the alternative to traditional agriculture, hydroponics is being 

recognized as beneficial for many important reasons. Hydroponic yields 

require up to 50 per cent less land to grow the same amount of produce, 

and as the world’s arable lands are diminished from overfarming and 

climate change, hydroponics takes the pressure off the environment by 

leaving more land available for wildlife reserves, biospheres, and other 

protected areas. Drought-ridden areas like California will appreciate 

the fact hydroponics uses only 10 per cent of the water needed for 

growing in soil and far less chemicals and fertilizers as much as 60 per 

cent less are required. By most reports, growing and transporting food 

around the globe accounts for as much as 30 per cent of all greenhouse 

gas emissions. With hydroponics, we can grow almost anything right 

where we live, reducing the need for carbon emissions. This is especially 

important for people who live in the Far North. More and more, programs 

are being created to provide fresh produce for those who live in northern 

communities, reducing the need to ship relatively small amounts of 

food while providing food security with fresh, inexpensive fruits and 

vegetables. It is with these shifts in mind that we’ve made some editorial 

changes in Maximum Yield. As you may have noticed, on our cover we’ve 

changed ‘indoor gardening’ to ‘modern growing’. As the industry evolves, 

so are we. Our content will include a wider look at the advancements in 

the growing world, both indoors and out. As we flip the calendar from 

2016 to 2017, we are taking a new perspective on the world of modern 

growing, and we look forward to bringing these stories to you. We also 

wish you and your loved ones the very best for 2017. In the meantime, 

we hope you have as much fun reading this issue as we did putting it 

together. As always, thanks for reading Maximum Yield and if you have 

any questions feel free to contact us at editor@maximumyield.com.

Hopelessly Hooked 

Getting your feet wet in 

hydroponics is not easy. 

However, when my local 

shop gave me a copy of 

your informative magazine, it 

answered a lot of questions on 

how to get started and what I 

needed. I am hopelessly hooked 

on Maximum Yield now. Thanks!

Romana 

Looking for Alternatives 

I would like to know if there are any alternative/substitute 

elements for potassium nitrate and potassium hydrogen 

phosphate for the purpose of making hydroponic nutrients. 

Mahmud 

Editor’s Note: Great question! For input, we went to 

Harley Smith, a former Maximum Yield contributor and 

the director of research at NPK University. He says, 

“Potassium nitrate and monopotassium phosphate 

are the preferred sources of phosphorus and 

potassium in hydroponics because of their solubility. 

Potassium sulfate is an alternative for potassium, 

but it’s not quite as soluble. Monoammonium 

phosphate is an alternative source of 

phosphorus, but it’s fairly acidic and it 

adds quite a bit of ammonium nitrogen. I 

use them mainly as supplements.” 

WE WANT TO HEAR 

FROM YOU! 

Did something in this issue of 

Maximum Yield catch your eye? 

Do you have an idea of a topic 

you’d like to see covered in a 

future issue? We welcome letters 

to the editor! And if you have 

a question or concern 

about what is happening 

with your plants, we’d 

be happy to pass on 

your question to one

Q 

What are the maximum light and CO 2 levels that can be applied to 

a plant before destroying it? Please note that limiting factors are all 

under control. Thanks! 

– Michael 

A 

Thanks for writing in. That is a good 

question. Let’s first look to the sun 

for some information. The sun is the 

Earth’s grow light and produces more 

than 100,000 lux, or roughly 10,000 

lumens, per square foot. This can be 

even higher when under direct sun. 

Lumens are a measure of the amount 

of light cast on one square metre. 

Most styles of artificial lighting do 

not provide anywhere close to that, 

but more important than lumens, 

which refers to the amount of visible 

light, is the amount of usable light. 

Plants see light differently than we 

do. They utilize much more of the red 

and blue spectrums of light, which 

the human eye is not as sensitive to. 

Plants use light during the process 

of photosynthesis. For this reason, 

it is important that your grow 

lights produce light waves in the 

wavelength ranges that are useful 

for plants, primarily the 400-700 

nanometre range. Most lights 

cover all spectrums, but some are 

manufactured to produce light in 

certain spectrums more than others. 

Let’s go back to lumens and how 

much can be used. Illuminance is 

the way most growers judge their 

light. Most agree that ideal light 

levels fall somewhere in the range 

of 30,000-60,000 lux for vegetative 

growth and between 50,000-80,000 

lux for the flowering stage. Serious 

plant problems surface at light levels 

above these, not to mention heat. 

CO 2, which is also involved in 

photosynthesis, is also essential for 

plant growth, but there is a threshold 

of how much your garden will use. 

Ambient levels of CO 2 hover around 

400-500 ppm. When you increase 

that level to around 1,000-1,500 ppm, 

you will see an increase in your 

yields and your plants will be much 

healthier. If the level rises to 2,000 

ppm or higher, you will begin to see 

negative effects such as CO 2 burn. It 

is best not to allow your CO 2 levels to 

increase this high. Doing so not only 

hurts your garden, but it wastes CO 2 

and money. As far as your choice of 

products, I would suggest using an 

all-natural form of CO 2 production 

versus a propane burner system or a 

tank system. The burners create heat 

and require the use of fossil fuels, and 

tanks are cumbersome and must be 

refilled often. 

You should supplement your garden 

with CO 2 during both the vegetative 

stage, as well as the flowering stage. 

If you encounter high temperatures, 

CO 2 will help your plants tolerate the 

high heat. In some instances, it may be 

what saves your garden from disaster.

LUMENS 

The lumen (lm) is a unit of luminous flux; a measure of the total quantity of 

visible light emitted by a source. Lumens are related to lux in that one lux is 

one lumen per square metre. The lumen is a measure of the total amount 

of visible light emitted from a given source, dependent on spectrum. Watts 

(W) is the measure of the amount of energy required to light a product, 

whereas lumens measure the amount of light produced. The more lumens 

in a light bulb, the brighter the light.

Small Hydroponic Farm Springs up in Newfoundland 

A family that’s been farming for 165 years in the St. John’s area is embracing hydroponics 

on a trial-run basis. Lester's Farm is hoping to grow a steady supply of leafy vegetables 

during the off-season from December to June. Farmers are growing four different types of 

lettuce, a couple of types of kale, green onions, basil, cilantro, and Swiss chard. If all goes 

to plan, they'll harvest 400 to 600 heads every week up until June. “We've gotten pretty 

good at storing our traditional Newfoundland vegetables for 12 months a year, but this is 

something that we’re really missing. During the winter, we’ll be able to displace the 

imported lettuce from California or Mexico,” says Chris Lester, one of the owners 

of the family farm. “Theres definitely a bit of nervous excitement. Weve been 

looking at this for seven or eight years,” he says.

GROWING TIPS, NEWS AND TRIVIA 

Students Win Award for Hydroponic Project 

A project to help address food security issues in northern climates earned 

a group of Memorial University students its second international title 

at the 2016 Enactus World Cup in Toronto last fall for its hydroponic 

farming endeavour, Project Sucseed. The organization makes and 

sells affordable hydroponic kits made from recycled materials and 

built by at-risk youth. The kits are being used in several northern 

communities in Newfoundland and Labrador, Nunavut, and New 

Brunswick. Jared Petten of Port de Grave worked with the finance team on 

the project. “We knew we had a really good project that addressed a really 

big need here in Newfoundland and especially anywhere in the world,” 

he says of their victory. “We had a collection of other team members 

come up with how we could use hydroponics to address those needs,” he 

adds. Currently, Project Sucseed is partnering with Tim Hortons to share 

hydroponic systems with schools across Canada.

Greenhouse Canada Honours Young Entrepreneurs 

A greenhouse operator in the High Prairie area of Alberta has been selected as one of 

the top 10 young Canadian gardening entrepreneurs outstanding in her field. Christie 

Pollack of Christie’s Gardens and Greenhouses was named in the Top 10 Under 40 by 

Greenhouse Canada. “She’s already an industry leader in social media marketing, 

including an exceptional website, blog, and online catalogue,” states a news release 

from Greenhouse Canada. Pollack has been working for 16 years in the industry, 

beginning with part-time work as a teenager in a local greenhouse. She now 

runs her garden centre with her husband, Tanner. Pollack was one of 

four growers from Alberta who made the list, with others from 

Morinville, Lacombe, and Medicine Hat. “For four of us from 

Alberta to get awards shows that Alberta is a happening 

place in the greenhouse industry,” says Pollack. “Alberta has 

a small greenhouse industry compared to BC and Ontario.”

Alberta Greenhouse Growers 

Brace for Carbon Tax 

The Alberta Greenhouse Growers Association is bracing for the provincial carbon 

tax to come into effect in January 2017. Association spokesperson Anna De Paoli 

says the tax will lead to an increase in imported produce and the loss 

of some greenhouses. The greenhouse industry employs more than 

4,000 people in the province. Ideally, Albertan growers would like to 

see a rebate program similar to the one in British Columbia, where 

growers get an 80 per cent rebate on the carbon tax they pay. “What 

we’re asking the government to do is create a level playing field and 

to give the growers in Alberta rebates similar to those in BC so we can 

compete fairly in the same market,” De Paoli says. Alberta’s carbon levy 

will begin at a rate of $20 per tonne beginning Jan. 1. One year later, 

the levy will increase to $30 per tonne.

Modular Farm Launches 

First Portable Container Farm 

Canadian start-up Modular Farms Inc. released its first modular farm unit at an open 

house event in Brampton, Ontario, last November. Originally designed for Canada’s 

Far North, the portable container farm can grow lettuces, leafy greens, and herbs 

in the harshest, most remote environments. “We’ve created a product that can work 

virtually anywhere in the world,” says Eric Amyot, the company’s co-founder and 

CEO. “We’ve designed a scalable, modular, portable, and self-contained indoor 

farming system that literally gets delivered on a truck and plugged in to start 

growing, with yields twice as high as any other farming system we’ve seen to 

date.” In 2017, the company plans to release add-on modules, such as those for 

water capture, storage, and a micro-grid. This will give farmers the flexibility to 

scale their business. Modular Farms will also start manufacturing in Australia, 

Singapore, and China in 2017.

Investing in Food and Health Research 

Canadian governments have invested $1.34 million in the Winnipeg-based Canadian 

Centre for Agri-Food Research in Health and Medicine (CCARM) to purchase a 

specialized piece of equipment and conduct economic research about the connections 

between food and health. The new nuclear magnetic resonance imager at the centre 

will be used to detect different chemical compounds in food, making it possible to 

isolate which are responsible for providing health benefits. The CCARM is a unique 

unit within the St. Boniface Hospital Research Centre that leads scientific and clinical 

studies about the connections between food and health. Over the next two years, the 

research will focus on "nutrition economics," evaluating the links between foodbased 

natural health products, the health care system, and the agri-food sector. For 

example, existing research may show certain foods can help prevent certain 

diseases or improve an individual’s overall health. Nutrition economics 

research tries to determine if measurable savings in the health care system 

are created as a result.

CO 2 Meter Day/Night CO 2 Monitor and Controller 

The Day/Night CO 2 Monitor and Controller from CO 2Meter is ideal for growrooms 

and greenhouses and has the most popular features requested in a CO 2-enrichment 

controller. It is also easy to install and use. Growers simply mount the controller in their 

growroom—all cables and hardware are included—and then plug it into a standard wall 

jack. Real-time CO 2 levels and temperatures in the room are displayed on-screen. To 

control CO 2 levels, plug a CO 2 generator or regulator into the built-in 110-220-VAC 

piggyback power cord. When the minimum CO 2 level is sensed, the power turns on. 

When the maximum level is reached, the power turns off. This controller also has a 

built-in photo sensor that shuts off the CO 2 when it senses darkness. Photo sensors save 

money and energy by ensuring growers are only supplying CO 2 during the light cycle.

Uber Nutrients Re-Cover is the only product on the market 

that was specifically designed to reverse and correct the 

less-than-desirable visual and physical side effects that can 

occur with the use of commonly used height-controlling 

plant-growth regulators. The use of PGR height controllers 

often results in plants with little essential oil production and 

moderate sized, but very compact and hard flowers that are 

then susceptible to moulds. Re-Cover fixes these common 

symptoms of PGR stress by restarting 

growth and development pathways, 

thus reviving cell division. This 

accelerated regeneration gives 

you yet another big burst in flower 

size that returns proper density to 

the flowers and gives you sweetsmelling, 

fully mature plants. 

Re-Cover is free from PGRs and 

harsh chemical agents; it restores 

your plants through the use of an 

acetylated form of lecithin and its 

unique TRx1 Peptide Suite.

ANOTHER WAY TO KILL PATHOGENS 

ecrets 

by Kathryn Van Druff | Most people don’t think of using colloidal silver to cure their own health, so it’s 

no surprise gardeners don’t think of it to improve their plants’ health, either. Kathryn Van Druff gives us 10 

secret benefits of ionic colloidal silver in the garden that will make you wonder why it’s not more common. 


SILVER SECRETS 

tenaciously targets the bacteria, parasites 

and other pathogens. 

In his published work, Use of Colloids 

in Health & Disease, in 1919, Alfred 

Searle wrote: 

“Applying colloidal silver to human 

subjects has been done in a large 

number of cases with astonishingly 

successful results. For internal 

administration, orally or hypodermically, 

it has the advantage of being 

rapidly fatal to parasites without 

toxic action on its host.” 

From a gardening perspective, this sort 

of result opens the door to remarkable 

possibilities. In particular, it suggests 

a rapid remedy to common garden 

pests and problems without harming 

the plants, helpful pollinators, or the 

humans who consume the ensuing fruits 

or vegetables. Here are some of the top 

ways your garden can benefit from a 

touch of colloidal silver. 

“KNOWN AS 

NATURE’S 

ANTIBIOTIC, IT’S 

NO SURPRISE THAT 

COLLOIDAL SILVER 

CAN ALSO OFFER 

PREVENTATIVE, 

THERAPEUTIC, 

AND RESTORATIVE 

PROPERTIES TO 

OUR PLANTS AND 

OUR GARDENS.” 

You may have heard of colloidal 

silver’s healing powers in human 

health. Some people use it when they 

feel a sinus infection coming on, while 

others have used colloidal silver to 

treat skin conditions and infections, 

including bacteria, yeast, viruses, 

and parasites. Known as nature’s 

antibiotic, it’s no surprise that colloidal 

silver can also offer preventative, 

therapeutic and restorative properties 

to our plants, and our gardens. 

Colloidal silver is essentially pure 

water with ultra-tiny nanoparticles 

of silver suspended inside. The ionic 

form of silver is capable of killing 

more than 650 different pathogens. The 

US Environmental Protection Agency 

(EPA) named silver as an oligodynamic 

biocide, which means it attacks 

primitive life forms but doesn’t harm 

more mature organisms. The beauty of 

using colloidal silver in the garden is 

that it’s very safe for the plants, but it 

An Organic Alternative to Potentially 

Harmful Chemicals and Pesticides 

Whether you’re growing commercially 

or simply for your family’s dinner table, 

no one wants extra chemicals on their 

fruits and vegetables. When treated with 

pesticides, plants tend to absorb topical 

chemicals. Colloidal silver is a safer, 

more organic alternative to many of the 

poisons marketed for gardens and farm 

pest prevention. 

Effective Eradication Plants of Bacteria, 

Viruses, Fungi, and Eggs 

Colloidal silver effectively inactivates 

the oxygen metabolism enzyme needed 

to sustain life for undesirable organisms. 

Spraying colloidal silver onto 

plants infected with bacteria, fungi, and 

viruses swiftly causes these undesirable 

organisms to suffocate and perish, 

all without the negative effects of traditional 

pesticides or the toils of other 


pest removal methods. An application 

of colloidal silver also is reportedly safe 

for children and pets that may come into 

contact with the plants. 

No Harm to Pollinators 

Honeybees, ladybugs, and other beneficial 

insects do not seem to have a negative

Bigger Fruits and Vegetables 

In a study published in the March 2010 

issue of the journal Mycobiology, green 

onions were treated with silver nanoparticles 

at the roots to eradicate Sclerotium 

cepivorum fungal infections. In addition 

to clearing up the fungus, the silver 

increased the fresh weight and the dry 

weight of the onions, producing larger, 

more desirable vegetables. 

Greener Leaves and Stronger Roots 

Using ionic colloidal silver in the garden 

can transform the overall health of 

the plant. In addition to treating and 

preventing pathogens, viruses, and 

fungi, the silver nanoparticles can 

impact the strength of the root system 

and the size and hue of the leaves. 

Large, vibrant green leaves indicate a 

truly healthy plant.

SILVER SECRETS 

Better Plant Immunity and Improved 

Cell Rejuvenation 

People may turn to colloidal silver 

supplements for a variety of illnesses 

and infections, from swimmer’s ear to 

pink eye. The silver is known to improve 

a person’s immunity, so it makes sense 

that plants can also gain a beneficial 

immune boost. Colloidal silver helps 

to make the plants more robust in 

preventing issues before any problems 

even occur, but also in recovering from 

damage caused by nuisance organisms. 

“USING COLLOIDAL SILVER IN YOUR WATERING CAN, 

RAIN BARREL, OR OTHER WATER COLLECTION SYSTEM 

ALLOWS YOU TO ENSURE THE WATER IS FREE FROM 

BACTERIA, ALGAE, AND PATHOGENS BEFORE YOU 

WATER YOUR GARDEN, GIVING YOUR PLANTS PURE, 

HEALTHY WATER.” 

No Pathogen Immunity Over Time 

One of the main problems with traditional 

antibiotics is that bacteria can morph over 

time, becoming immune or less responsive 

to the effectiveness of the drugs. Unlike 

antibiotics, pathogens, viruses, fungi, and 

bacteria do not develop immunity to silver 

nanoparticles. Applying colloidal silver 

in the garden should continue to offer 

improvements for the foreseeable future. 

Safety to Gardeners 

Many people ingest colloidal silver or 

apply it topically to treat various conditions. 

If there is a chance you ingested 

colloidal silver, you should always make 

absolutely certain that you are using true 

colloidal silver and not silver protein or 

ionic silver, as some toxicity may occur, 

depending on use. Check the Silver 

Safety Council’s Silver Safety Pyramid 

(silversafety.org) to ensure proper daily, 

short-term and lifetime usage. 

Water Purification 

Colloidal silver possesses a unique 

ability to purify water supplies 

and reservoirs. Various airlines 

employ silver water filters to keep 

waterborne illnesses at bay when 

airborne. NASA also leveraged the 

power of silver for its purification 

properties, developing a copper/ 

silver ionization process to sanitize 

the water. The purification process 

removes bacteria and algae from 

the water, as evidenced by its original 

intended purpose of dispensing 

silver ions and killing bacteria in the 

potable water supply on the Apollo 

spacecraft. Using colloidal silver in 

your watering can, rain barrel, or 

other water collection system allows 

you to ensure the water is free from 

bacteria, algae, and pathogens 

before you water your garden, giving 

your plants pure, healthy water. 

No Residue Left Behind 

After spraying colloidal silver onto 

your plants, you can rest easy knowing 

that no residue remains. Your fruits 

and vegetables are still perfectly 

safe and healthy for your family to 

enjoy. Colloidal silver may also be 

combined with water and vinegar to 

create a fruit and vegetable wash. 

The Centers for Disease Control and 

Prevention reported in its recent study, 

“Epidemiology of Foodborne Norovirus 

Outbreaks, United States, 2001-2008”, 

that produce accounted for 46 per cent 

of all foodborne illnesses across 17 

food categories. In terms of norovirus, 

more than half of the cases were tied to 

produce, particularly leafy vegetables 

and fruit. According to a recent study 

published in the journal, Applied and 

Environmental Microbiology, colloidal 

silver can deactivate murine norovirus 

(mouse-based norovirus). 


“PLANTS MAY 

HAVE THE ABILITY 

TO CONTROL 

THEIR RATE OF 

ABSORPTION OF 

COLLOIDAL SILVER.” 

How to Apply Colloidal Silver 

to Your Garden 

Colloidal silver works rapidly and efficiently. 

In many cases, it needs only 

moments of contact with the fungus 

spores or other organisms. Applying 

colloidal silver to your garden can be a 

relatively effortless process. 

• Apply small amounts of a diluted 

solution to the roots to fortify 

the plant while also preventing 

root rot. 

• Mix a diluted solution containing 

one tablespoon of colloidal silver 

and one litre of water and spray on 

the leaves and flowers. 

• Add to your watering can at the rate 

of one tablespoon per litre of water. 

Interestingly, plants may have the 

ability to control their rate of absorption 

of colloidal silver. Researchers found 

that the more nanosilver they applied 

to the green onions, the less the plants 

absorbed. This indicates that the plants 

absorbed only what they needed to 

promote their protection and healing. 

One study suggests that, over time, 

soil can become contaminated with the 

silver particles, causing the plants and 

young seedlings to respond in a certain 

way. In this study, pine tree seedlings 

exhibited reduced growth. If heavy 

silver saturation is a concern, you may 

find container gardening to be a good 

place to start with your silver application. 

This way, you can replace the soil 

any time you choose if things aren’t 

going the way you envisioned. With 

this in mind, moderation may be the 

key to using colloidal silver.

Cal-Mag Supplements: 

A One-Two 

Punch 

for Plants 

by Cory Hughes 

If the leaves in your garden are starting to grow in misshapen 

patterns or are showing spotty, discoloured patches, odds are 

you have a nutrient deficiency. Identifying deficiencies can 

be a challenge, but once you have eliminated your primary 

macronutrients from the list, your problem probably lies with 

your secondary nutrients—calcium and magnesium. Fertilizing 

your garden with a cal-mag supplement will strengthen your 

plants and ensure a lush, green hue returns to your beauties. 


Calcium and magnesium are two of the 

three secondary nutrients required 

by plants, the third being sulfur. They 

are secondary in as far as quantities 

required for growth, not importance 

of function. Simply put, calcium and 

magnesium are necessary for plant 

growth and development and are easy 

to fix in the case of a deficiency. While 

nitrogen stands as requiring the highest 

levels in a nutrient feed, secondary 

nutrients calcium and magnesium only 

require about eight to 10 per cent of that 

amount. While their required levels are 

much lower, their importance can’t be 

understated. 

Calcium 

Calcium is important for strengthening 

a plant’s cell walls and maintaining 

its structure. The importance of calcium 

becomes evident when you see degradation 

of the leaves, which eventually 

shows up as discolouration and cankerlike 

sores. When calcium is absent, the 

integrity of the cell wall falls apart. 

Calcium is not mobile inside the plant, 

so the plant cannot borrow from nearby 

areas to make up for local deficiencies. 

Instead, calcium depends on transpiration 

to reach its destination. 

Once absorbed by the root system, 

calcium is then pulled through the plant 

and deposited where needed as excess 

water, which played a role in the transpiration 

process, escapes the plant 

through tiny pores called stomata. As 

the process depends on the flow of water 

through the plant, any factor that affects 

hydration levels, such as humidity and 

temperature, can have a significant 

impact on calcium levels, even if your 

feed blend is properly mixed. 

Calcium deficiencies also result in 

stunted root growth. Many times, even if 

the soil is rich in calcium, it may not be 

in a form readily available for absorption 

by the plant. This is where supplementation 

comes in. By supplementing 

calcium in a form that is geared 

toward maximum uptake, you increase 

the amount of bio-available calcium 

in the soil, which results in a muchneeded 

boost for your plants. A plant 

with increased calcium levels will result 

in a higher than usual pH in the soil. 

However, finding a higher than usual pH 

level is not necessarily an indicator of 

well-balanced calcium levels. 

Magnesium 

Magnesium deficiencies are easily identified 

by a yellowing of the leaves with 

distinct green veins. Since magnesium 

can float freely throughout the plant, the 

veins remain green as newer leaves are 

actively sucking up what magnesium is 

available. This results primarily in deficiencies 

in older leaves. 

Magnesium is the key element in chlorophyll, 

which gives plants their vibrant 

green colour. This secondary plant nutrient 

also plays numerous roles in the 

photosynthesis process, including the 

activation of enzymes and the creation 

and transportation of sugars throughout 

the plant. The most common cause of 

magnesium deficiencies is simply a lack 

of adequate application. 

Enter the One-Two Punch 

Balancing your magnesium and other 

secondary nutrients is vital since disproportional 

amounts can limit uptake. 

Fortunately, treating calcium and 

magnesium deficiencies can be handled 

in one shot. Adding a cal-mag supplement 

to your plants can help alleviate 

many of the symptoms showing up 

in your garden. There are a handful of 

approaches to cal-mag supplementation. 

“ 

While supplementing 

with calcium by itself, 

it is possible to use 

a foliar application, 

while the vast majority 

of cal-mag supplements 

require introduction to 

the root system. 


29

A ONE-TWO PUNCH FOR PLANTS 

“ 

Calcium is not mobile 

inside the plant, so the 

plant cannot borrow from 

nearby areas to make up 

for local deficiencies. 

You can head to your local grow shop 

and pick up one of a handful of excellent 

quality fertilizers, or you can mix up 

a batch at home. While supplementing 

with calcium by itself, it is possible to 

use a foliar application, while the vast 

majority of cal-mag supplements require 

introduction to the root system. 

Mixing your own cal-mag supplement 

at home is as easy as measuring out raw 

nutrient salts. Each of the commercial 

manufacturers has their own formulation, 

but they all follow similar methods, 

tweaking things here and there to 

achieve specific results. If you want to 

mix up your own cal-mag, start with 

magnesium sulfate, otherwise known as 

Epsom salts. Epsom salts are a staple 

of the gardening community for magnesium 

supplementation and make the 

perfect base for your cal-mag mix. 

The next ingredient is calcium nitrate. 

Calcium nitrate is a common plant fertilizer 

used in standard feed mixes. As 

both calcium and magnesium come in 

a chunky, powdery form, they need to 

be dissolved in water at specific ratios. 

Taking into consideration personal 

preference, your calcium should be at a 

parts per million (ppm) of at least double 

that of magnesium. One example of a 

homemade cal-mag has a ppm ratio 

as follows: 120 ppm magnesium and 

260 ppm calcium. This breaks down, 

per gallon, to 5.8 grams of calcium 

nitrate and 4.6 grams of magnesium 

sulfate (Epsom salts). You can always 

adjust your mixture to compensate for 

specific deficiencies, depending on the 

symptoms you see in your garden. 

If all of this sounds like too much 

work, there are many cal-mag formulations 

out there that are ready to 

go. Many of them include additional 

nutrients like iron or nitrogen, but 

they all stay within certain parameters 

regarding their levels of calcium 

and magnesium. 

Nutrient deficiencies in the garden 

can arise for a multitude of reasons. 

Everything from high heat and humidity 

to an imbalance in your fertilizers 

can result in calcium and magnesium 

deficiencies. The decaying of leaf structure, 

fading of leaves, and yellowing 

with green veins are indications your 

calcium and magnesium levels are 

low. As these two nutrients play such 

an important role in plant growth and 

development, it is important to be able 

to recognize the symptoms of deficiency 

quickly and respond appropriately. 

Understanding the roles calcium and 

magnesium play in your garden is vital 

in knowing how to correct problems 

that arise from deficiencies.

Who is This 

Kelvin Guy? 

If the Kelvin scale 

was a character 

in a suspense 

novel, he’d be the 

misunderstood loner 

who possessed 

information vital 

to untangling the 

convoluted plot. 

by Sara Elliott 


If you’re a little unclear about the kelvin (K) 

rating on your grow light, you’re not alone. 

The Kelvin scale can be counterintuitive in 

a couple of ways, but understanding it is an 

important detail when pursuing the goal of 

healthy plant development. 

Kelvin and Temperature 

Let’s start with a simple refresher. Kelvin is 

a temperature measurement often preferred 

in scientific circles because it can be useful 

in a number of different contexts. The 

bottom of the scale denotes absolute zero, 

a condition where there is no measureable 

kinetic energy in an object. It’s as cold as it 

can possibly be. The coldest objects in the 

universe will have a rating of zero on the 

Kelvin scale. 

The incremental measurements when using 

kelvin are the same as when using Celsius 

(˚C), another type of temperature scale. 

Where they differ, however, is the definition 

of zero. On the Celsius scale, zero is the 

freezing point of water. As mentioned above, 

zero on the Kelvin scale is absolute zero. For 

reference, 0K is equal to -273.15˚C. 

“ 

” 

The coldest objects in 

the universe will have 

a rating of zero on 

the Kelvin scale. 


33

WHO IS THIS KELVIN GUY? 

The Kelvin Scale and 

Colour Temperature 

Kelvin is a fundamental unit of thermodynamic 

temperature, which 

means it measures heat. So, it would 

make sense that colour temperature 

ratings are really heat ratings, right? 

Well, yes and no. 

Although kelvin is a heat measurement, 

it doesn’t quantify the amount 

of heat a light fixture is pumping into 

your growroom when applied to colour 

temperature. Instead, it measures how 

closely a light source approximates 

full-spectrum sunlight. The Kelvin scale 

can be used to do this by exploiting 

the colour changes that occur when an 

object is heated. 

For a real-world example, think of an 

incandescent filament. As the filament 

gets hotter, it first begins to glow red 

then orange, yellow, and so on. These 

colour changes are measured as heat 

values in kelvin, but correlate to colour 

spectrum changes, too. By applying the 

Kelvin scale to these specific hues or 

colour ranges, it’s possible to select light 

values favourable for specific phases of 

plant photobiology. Kelvin can also be 

used to identify full-spectrum lights that 

most closely approximate sunlight. 

“ Although kelvin is a heat 

measurement, it doesn’t 

quantify the amount 

of heat a light fixture 

is pumping into your 

growroom when applied 

to colour temperature. 

” 

COLOUR 

TEMPERATURE 

& YOUR HOME 

LIGHTING 

If you think the value of colour 

temperature is limited to the 

confines of your growroom, 

guess again. The technology 

has widespread uses, some 

of which touch pretty close to 

home. Colour temperature is 

used in photography, publishing, 

the film industry, and astrophysics. 

It is also a key component 

in lighting for business 

and residential applications. 

Take a look at your stash of 

everyday lightbulbs and you’re 

likely to see they include a 

kelvin range. Popular ENERGY 

STAR* bulbs are rated for both 

energy efficiency and color 

temperature. Their color temperature 

ratings can help you 

identify and consistently purchase 

the light hue, or hues, 

that function best for the room 

or task you have in mind. 

Generally, a colour temperature 

range of 2,000-3,000 K produces 

warm, cozy yellow light great for a 

bedroom, dining room, or family 

room. A higher range of 3,100- 

4,500 K produces cool white 

lighting effective for a kitchen 

workstation or a desk lamp. 

Lighting in the white, blue range 

of 4,600-6,500 K works best in 

spaces where visibility is critical, 

such as stairways, entryways, and 

garage workspaces. 

*ENERGY STAR is a joint venture 

between the US Environmental 

Protection agency (EPA) and the US 

Department of Energy (DOE) tasked 

with establishing standards for energy 

efficient products. Goods that carry 

the ENERGY STAR logo can be up 

to 30 per cent more energy efficient 

than their unrated counterparts. 


WHO IS THIS KELVIN GUY? 

Is Blue Cool or Hot? 

Let’s look at this concept a little more 

closely. Light sources can be somewhat 

classified based on their kelvin values 

using a scale from 1,000-8,000K. Here are 

some general examples to give you an 

idea of how the scale relates to different 

types of light: 

• Candlelight: 1,800-1,930K 

• Sunlight at Sunrise or Sunset: 

2,000-3,000K 

• High Pressure Sodium (HPS): 2,200K 

• Incandescent: 2,700-3,000K 

• Compact Fluorescent (CFL): 2,700- 

6,500K (various) 

• Metal Halide (MH): 3,200-5,500K 

(various) 

• Sunlight at Noon on a Clear Day: 

5,000-5,400K 

As you can see, candlelight, which is 

toward the red end of the visual spectrum, 

has a lower kelvin rating or range 

than light on the white or blue end of the 

spectrum, such as that produced by a 

fluorescent fixture in an office building. 

This is another way in which kelvin 

can be confusing. In colour psychology, 

humans tend to associate blue hues 

with cooler environments, often defining 

them as calmer, chillier shades. 

However, blue has a higher kelvin 

rating and colour temperature than that 

of red, orange, or yellow light. Going 

back to our incandescent filament 

example, a white or blue filament is 

hotter than a red or yellow one. 

Colour Temperature and 

Visible Light Wavelengths 

It may seem possible to convert light 

wavelengths to colour temperatures. 

However, the relationship between the 

two isn’t as intuitive as it might appear. 

Visible light within the electromagnetic 

spectrum—that is, all the 

colours of the rainbow— 

has a wavelength range 

of 390-700 nanometres 

(nm). For example, blue 

light has a wavelength 

of around 475 nm and 

red light has a wavelength 

of about 650 

nm. Colour temperature 

ratings, however, 

don’t represent a 

single wavelength 

value. These ratings 

actually contain 

many, many wavelengths 

that collectively 

appear as a 

particular hue. 

“ It may seem possible to 

convert light wavelengths 

to colour temperatures. 

However, the relationship 

between the two isn’t as 

intuitive as it might appear. 

” 

Colour Temperature 

and Plants 

In nature, plants have access to 

balanced, full-spectrum sunlight that 

includes all light wavelengths. During 

photosynthesis, most plants employ the 

entire visible light spectrum. To perform 

some other functions, though, they rely 

heavily on specific portions of the light 

spectrum. For example, during early 

growth, light on the blue end of the spectrum 

(6,500K) triggers leaf, stem, and root 

development. Later, an increase in red 

spectrum light (2,700-3,000K) encourages 

and sustains flowering and fruiting. 

For indoor growers, understanding 

how plants use light makes it easier to 

manipulate colour temperature and use 

lighting efficiently in order to maximize 

the developmental potential of plants. 

Kelvin colour temperature ratings are 

useful measurements when determining 

the best light for different phases of plant 

development, but there are other lightrelated 

factors to think about, too. They 

include, but are not limited to, light intensity 

and duration (AKA daily light integral, 

or DLI), heat output, bulb longevity, 

equipment cost, and energy consumption. 

For the best results, understand what 

type of lighting your plants will need 

before you invest in equipment, and use 

tools like colour temperature to fine-tune 

your growing strategies.

BY ERIC HOPPER 

The root system of a plant is where essential 

nutrients are absorbed and distributed to the rest of 

the plant. As a plant grows and develops, so does 

the root mass. Indoor horticulturists who focus their 

energy on promoting and maintaining a healthy 

root system are more likely to have less problems 

and larger yields each garden cycle. 


Indoor horticulturists constantly strive 

to find techniques and products that 

will help increase their garden’s yields. 

Common sense will tell you that a plant 

with a strong and healthy root structure 

is more likely to have strong and healthy 

stems, leaves, and flowers. Simply 

put, healthy roots will equate to more 

bountiful harvests. Unfortunately, indoor 

growers do not always give a plant’s 

root system the attention it deserves. It 

is like the old saying “out of sight, out of 

mind”. Because the roots are generally 

hidden from a horticulturist’s view, they 

can often be forgotten. Horticulturists 

who focus some of their energy on 

making the plant’s root system thrive 

will usually have better yields and 

less problems overall. There are a few 

different ways for an indoor grower to 

help stimulate root growth and maintain 

a healthy root mass. 

OXYGEN 

Many horticulturists don’t think about 

the important fact that plants need 

oxygen to thrive and survive. Most of us 

think of plants as living organisms that 

produce oxygen during photosynthesis 

"BECAUSE THE ROOTS 

ARE GENERALLY 

HIDDEN FROM A 

HORTICULTURIST’S 

VIEW, THEY CAN OFTEN 

BE FORGOTTEN." 


37

STRENGTHENING YOUR PLANT’S ROOTS 

“IT IS CRUCIAL IN HYDROPONIC SYSTEMS 

TO FOCUS ON THE TEMPERATURE 

OF THE NUTRIENT SOLUTION AND 

MECHANICAL AERATION.” 

(a process that requires CO 2), not as organisms that also need 

oxygen to grow. Like other organisms, plants need oxygen to 

perform cellular respiration. Roots grow like other parts of the 

plant, but since they are under soil or contained in a hydroponic 

system, they are not exposed to light and cannot photosynthesize. 

Instead, they gain energy for growth by cellular 

respiration that requires oxygen and releases CO 2. This is why 

a plant’s root mass must be exposed to some form of oxygen. 

For soil growers, the soil’s texture will determine the amount of 

open spaces for air. In hydroponic systems in which the plant’s 

roots are submersed in water, the roots will rely on dissolved 

oxygen found in the nutrient solution. This dissolved oxygen 

will need to be replenished as the plant uses it. In both soil 

and hydroponic systems, if there is not a sufficient supply of 

oxygen, the roots will not be able to survive and will die off, 

eventually killing the entire plant. 

HOW TO INCREASE OXYGEN FOR THE 

ROOT SYSTEM IN SOIL 

To increase a soil’s oxygen capacity, a grower can add a variety 

of soil amendments. Perlite, pumice, hydroton, or any other 

porous substance can significantly increase a soil’s ability to 

harbour oxygen. Coco coir is another soil amendment praised 

for its ability to not only hold oxygen, but also have good water 

retention. Most prepackaged soil mixes will contain at least 

one amendment aimed at increasing aeration. However, it is 

not a bad idea for indoor growers to add more aeration amendments 

to a soil mix. In fact, well-aerated soil can provide two 

advantages. First, as well-aerated soil increases the soil’s 

ability to hold oxygen, it provides the plant’s root system with 

all the oxygen it needs to grow and flourish. Second, wellaerated 

soil needs to be watered more frequently, which gives 

the indoor horticulturist the opportunity to implement a more 

aggressive feeding regimen. A good rule of thumb is to mix 

three to four parts prepackaged soil to one part perlite or other 

aerating amendment. This ratio will create a fast-draining soil 

that can hold a high amount of oxygen. 

HOW TO INCREASE OXYGEN FOR THE 

ROOT SYSTEM IN A HYDROPONIC SYSTEM 

It is crucial in hydroponic systems to focus on the temperature 

of the nutrient solution and mechanical aeration. The nutrient 

solution is usually contained in a reservoir, which needs 

to be mechanically aerated. Submersible pumps or air pumps 

that inject air into the reservoir are the best ways to replenish 

dissolved oxygen. Temperature is another crucial factor 

affecting the dissolved oxygen content of the nutrient solution. 

The ideal temperature for most hydroponic systems falls 

in the 18-21°C range. As the water temperature creeps above 

24°C, its ability to hold oxygen diminishes. This is why water 

chillers are an essential piece of hardware for any hydroponic 

system where the roots are fully submersed. In other hydroponic 

systems, the plant’s root system will be contained within 

some sort of inert medium. There are many different hydroponic 

specific media available and they all have one thing in 

common: the ability to hold a good amount of oxygen.

“THERE IS A VAST INVISIBLE 

WORLD LIVING IN AND AROUND 

THE ROOT SYSTEM OF VIRTUALLY 

EVERY PLANT ON THE PLANET.” 

R O O T S 

NUTRIENTS 

Aside from increasing the amount of oxygen provided to a 

plant’s root system, a grower can pay attention to the nutrients 

that will play a role in root health. A good blooming 

fertilizer will usually contain the nutrients needed for healthy 

root growth. Phosphorus and potassium are the two main 

nutrients associated with root growth. Many horticulturists 

like to use a blooming-base fertilizer in the clone and 

early growth stages. A blooming base fertilizer is likely to 

contain a higher ratio of phosphorus and potassium to nitrogen 

than a vegetative-base fertilizer. Phosphorus and potassium 

encourage plants to put out new root shoots and help 

to strengthen existing roots as they continue to develop. A 

diluted bloom fertilizer (one-quarter normal strength) makes 

a great nutrient solution for aerobic clone machines or for 

conditioning stonewool and other clone media. 

ROOT STIMULATORS (HORMONES) 

Plant hormones, known as auxins, can also be used to stimulate 

root growth. A couple of hormones commonly found 

in rooting gels are indole butyric acid and naphthylacetic 

acid. These two hormones are considered root stimulators. 

Although some growers will use these hormones to stimulate 

root growth in early vegetative stages, I have only used 

them to stimulate new roots on cuttings. Auxins are known to 

promote lateral root development so they are more suitable 

for cuttings versus seeds. 

BENEFICIAL MICROORGANISMS 

There is a vast invisible world living in and around the root 

system of virtually every plant on the planet. This microscopic 

world is made up of millions of bacteria and fungi 

that have evolved to have synergistic relationships with 

plants. Beneficial microorganisms are associated with root 

enhancement and overall plant growth enhancement. 

The most commonly used beneficial microorganisms supplemented 

by indoor horticulturists are beneficial fungi and 

beneficial bacteria. 

Mycorrhizae (Fungi) 

Mycorrhizae are naturally occurring fungi that form symbiotic 

relationships with more than 90 per cent of the world’s 

plant species. Mycorrhizae have even become a common additive 

in gardening products like prepackaged potting soils. 

Mycorrhizae fungi become an extension of the root system that 

can stretch far into the depths of the soil. This immediately 

broadens the plant’s access to vital nutrients and, therefore, 

increases growth. Mycorrhizae have synergistic relationships 

with the plant’s roots. The extending web of mycorrhizal fungi 

assimilates nutrients for the plant and, in return, the plant’s 

roots secrete sugars or carbon on which the fungi feed. Since 

the relationship between mycorrhizae and the plant’s roots is 

synergistic, it is safe to say that if a gardener has a healthy 

population of mycorrhizae in the soil or medium, he or she will 

usually have a healthy root system as well. 

Trichoderma (Fungi) 

Trichoderma are a group of fungi that are usually used by 

horticulturists as a natural defence against root damaging 

pathogenic fungi. Trichoderma can work wonders against 

pathogenic fungi that could otherwise destroy a healthy root 

system. In fact, some of the most powerful root rot treatments 


available are formulas rich in trichoderma. Trichoderma can 

help maintain a healthy, vibrant root system by fending off 

potential threats. In most cases, trichoderma can be added to 

a feeding regiment to maintain a healthy trichoderma population. 

After all, if there aren’t enough pathogens for the trichoderma 

to feed on, their population will diminish (not a bad 

thing). However, by maintaining a healthy population of trichoderma, 

a horticulturist can nip pathogenic fungi in the bud 

before they can negatively affect a plant’s root system. 

Beneficial Bacteria 

As with beneficial fungi, bacteria can be added to the soil 

or medium to break down organic matter, facilitate nutrient 

uptake, and add protection against pathogens. One huge 

advantage of using beneficial bacteria in indoor horticulture 

is that bacteria can quickly colonize and explode in population. 

The larger the population of beneficial bacteria, the 

quicker they can destroy pathogenic microorganisms and/ 

or break down organic matter. As with mycorrhizae, it is safe 

to say that if the soil has a bountiful population of beneficial 

bacteria, it is more likely to have a healthy root system. 

Providing plants with the right nutrients, hormones, and 

beneficial microorganisms are ways an indoor gardener can 

maximize the strength of a plant’s roots. Although mostly 

unseen, the root system of a plant is a huge factor in determining 

the overall success or failure of an indoor garden. 

At the end of the day, growers who spend the extra time on 

developing a strong, healthy root structure are more likely 

to achieve prolific yields and are less likely to encounter 

potentially devastating problems.

Plant 

Growth 

Regulator 

Plant growth regulators have their benefits, 

but they also have their drawbacks that can 

include health concerns for people who 

consume what they grow. Rich Hamilton 

explains what plant growth regulators are, 

what they do, and what questions consumers 

should be asking when purchasing them. 

principles 

By Rich Hamilton 


Starting with the basics, PGR 

stands for plant growth regulator, 

sometimes also referred to as 

plant hormones. Every plant naturally 

produces very small amounts of 

hormones to control its normal functions 

such as root growth, height, node and 

internode growth, flowering, quantity 

of flowers, fruit, and any other developmental 

growth. 

Plant growth regulators are a chemical 

or mix of chemicals that make a plant 

change beyond its naturally physiological 

growth actions, through the 

cells, organs, and tissues. It does this by 

either slowing down the rate of growth 

or maturation; speeding up the rate of 

growth or maturation; or altering the 

natural behaviour of a plant. Note that 

this does not include any substances 

which are intended as plant nutrients, 

including trace elements, plant inoculants, 

or nutritional chemicals. 

The term PGR has come to include 

many things, and not all of them are 

harmful. Some of the of major classifications 

of plant growth regulators are 

auxins, cytokinins, ethylene generators, 

gibberellins, and growth inhibitors/retardants. 

Auxins elongate shoots. 

They are primarily used to increase 

growth, flower formation, and root mass. 

Cytokinins stimulates cell division 

and are primarily used to increase root 

mass and new bud growth. Ethylene 

generators ripen fruit and are primarily 

used to ripen fruit uniformly, giving the 

plant consistent fruit size and weight. 

Gibberellins elongate cells and stimulate 

cell division and are primarily used 

to increase fruit and flower size. Finally, 

grow inhibitors and retardants stop or 

slow down growth. They are primarily 

used to increase flower production by 

shortening the internodes, make more 

node sites, and/or to completely stop the 

lateral growth of a plant. 

So the big question is, are PGRs 

illegal? Well, no, not if they are used 

on ornamental plants, but without 

going too far down the rabbit hole 

of what is and isn’t legal, what I can 

say is that some are prohibited for 

use on plants grown and intended 

for human consumption. 

Good Control 

PGRs are a great way to control plants. 

They will, if used in the right mixtures 

at the correct dosages, considerably 

improve the desired factors. PGRs can 

help a plant produce more flowers and 

fruits and assist in producing even 

consistent flowers and fruits. They can 

help you keep plant height consistent 

and reduce the time it takes for a plant 

to produce its flowers and fruits. They 

can also make a plant less susceptible 

to fungi, diseases, and pests. 

PGRs can control plants in order to 

preserve the balance between the 

modern world and the natural world. By 

that I mean they have been used to stop 

growth in trees growing too high, which 

otherwise would have to be destroyed 

to prevent them from growing under 

bridges, telephone cables, and in other 

urban locations damaging or obstructing 

footings, buildings, and foundations. 

At the other end of the scale, they can 

make houseplants stay manageable 

and become more resilient to stress and 

disease. PGRs are also used commonly 

and successfully within the retail flower 

business. They are used to make the 

flowers more appealing to the retail 

consumer by improving consistency in 

flower size and colour. 

Plant growth 

regulators are 

a chemical or 

mix of chemicals 

that make a plant 

change beyond 

its naturally 

physiological 

growth actions.

BALANCING PGR PRINCIPLES 

We’ve covered the positives, so what 

are some of the negatives? As is often 

the case, when something seems too 

good to be true, it usually is. 

A Moral Choice 

Most people, including shop owners and 

customers, would prefer not to sell or 

buy products that contain PGRs, if given 

a choice, but most do. There are several 

reasons for this, the first being the 

companies that produce the nutrients 

and additives do not always inform shop 

owners that their products contain PGRs, 

so the shop owner is none the wiser. 

On the flip side, some of the products 

that contain PGRs are so popular and 

sought after, a shop owner may find him 

or herself stuck with a moral choice. The 

owner can attempt to educate customers 

as much as possible on the benefits 

of non-PGR products but the bottom line 

is that they are a business, so if they 

don’t have the PGR products a customer 

wants in their store, they run the risk of 

losing that customer and sale to a rival. 

Finally, there are those people 

who are only interested in achieving 

the heaviest and most financially 

rewarding yield from the plant and 

are willing to overlook the health 

concerns related to PGRs. 

In reality, PGRs are out there and it is 

impossible to tell what plants they are 

in and at what levels. But this can all 

be taken care of if plants are flushed 

before harvest, right? 

Wrong. 

PGR chemicals are nearly all 

systemic, which means that once they 

are taken up into the plant, trace chemicals 

will always be in the plant, its 

flowers, fruits, roots, tissues, pollen... 

everything. Therefore, it follows that 

if you cannot be sure what levels of 

PGR are present in the additives you 

are using due to the lack of information 

given in the ingredients list, then 

you would have no idea of the level of 

potentially harmful PGRs in any part 

of your fully grown plant, including the 

fruit before and after harvesting. 

The Right Questions 

There is a lack of pretty much any regulation 

or regulative body on chemicals 

used in the hobbyist hydroponics 

industry. This means that most of the 

nutrient and additive companies don’t 

have to state whether their product 

contains any PGRs, the quantities 

contained or specify which PGR it is. 

The bad press surrounding PGRs, most 

notably that the majority of them are 

banned in most countries for use on 

plants and their fruits that are intended 

for human consumption, only adds to 

the desire to keep their presence in any 

products a secret. 

You’re probably thinking that surely 

the nutrient companies can’t knowingly 

put these chemicals in their 

products without telling the customer. 

However, like antibiotics in meat or 

chemical ingredients in packaged 

foods, the simple and honest truth is 

PGRs can control 

plants in order 

to preserve the 

balance between 

the modern 

world and the 

natural world. 



45

BALANCING PGR PRINCIPLES 

yes, some of them do. Not only that, 

they also don’t tell us. Like anything 

else you consume, know what you are 

buying. Here are a few questions to 

ask your retailer or a manufacturer 

when purchasing nutrients: 

● 1 What PGRs, if any, are in the 

products you sell? 

● 2 What will those PGRs do to 

the plant? 

● 3 Should they be used on 

anything intended to be 

consumed by humans? 

● 4 What effects will the 

chemicals have if the produce 

of the plant is consumed? 

The bottom line is that the next 

time you go to buy nutrients, ask 

if the product contains PGRs. Only 

by asking and buying better can 

we create a better, safer market for 

ourselves in the future. 

Most people, 

including 

hydroponics 

shop owners 

and customers, 

would prefer not 

to sell or buy 

products that 

contain PGRs, if 

given a choice.

GREEN THUMB 

TECHNOLOGY 

INNOVATING THE WAY 

WE GROW FOOD 

Hot off the heels of their fall 2016 

Kickstarter campaign, Green Thumb 

Technology, based in Squamish, 

British Columbia, is now taking 

pre-orders for its innovative household 

hydroponic system, the VeggieWall. The 

system’s unique, intuitive design is the result 

of 3.5 years of research and development. 

Co-founder and CEO Jen McGuinness talks 

about what the experience has been like so far. 

HOW DID YOUR BUSINESS 

GET ITS START? 

In July 2013, when I was researching how 

to make my patio garden vertical, I came 

across living walls. Inspired by these 

artistic, non-edible gardens, I set out 

to create an edible version. I called my 

friend of 20 years, Matthew, and we set 

out to develop the VeggieWall. 

HOW HAS IT EVOLVED 

OVER THE YEARS? 

We started with prototypes in our backyards. 

We consulted several designers 

and electrical engineers. Some 

courageous friends and family tested 

our prototypes and gave us feedback. 

In the fall of 2015, we finally nailed the 

design and received funding from the 

National Research Council of Canada. 

Then, in partnership with Emily Carr 

University’s industrial design department, 

we finalized our mould for manufacturing. 

The two of us have done 

everything out of our own pockets while 

working our current professions to 

launch Green Thumb. We ran a test run 

with our manufacturers in Langley and 

sourced and tested all the electronics. 

We are now taking pre-orders through 

our website, with the first VeggieWalls 

being delivered in April 2017. 

WHAT IS YOUR COMPANY’S 

PHILOSOPHY? 

Empowering people to grow food and 

live healthy, fulfilling lives! Plants 

lose their nutrients once picked. The 

most nutrient-rich food you can eat 

“IT IS SO CONVENIENT WHEN YOUR WALL 

IS BURSTING WITH VEGGIES AND GREENS 

IN THE COMFORT OF YOUR HOME.” 


“WE FOUND THAT CURRENT 

HYDROPONIC WATERING 

SYSTEMS WERE NOT ADEQUATE 

FOR WHAT WE WANTED TO DO, 

SO WE INVENTED OUR OWN!” 

is food that your grow yourself and 

harvest as you need it. It is so convenient 

when your wall is bursting with 

veggies and greens in the comfort 

of your home. It is easy to pick some 

fresh food to add to your dishes. 

Foodies can ascribe to how much 

better the taste of fresh food is. Not 

only is growing our own food better 

for our health, it reduces the impact 

on the planet. Growing our own food, 

even a small amount, helps take 

the burden off the Earth. With urban 

densification, we need to seek alternative 

ways to grow food. 

TELL US ABOUT YOUR FLAGSHIP 

PRODUCT, THE VEGGIEWALL. 

The VeggieWall is an indoor vertical 

vegetable garden that is affordable, 

easy to use, and looks great on your 

wall. Unlike other units that take up 

counter space or floor space, we have 

developed a garden that fits seamlessly 

into your living space. It can 

be mounted to your wall, hung from 

the ceiling, or placed on a stand. The 

VeggieWall grows more food in the 

smallest square footage of any garden, 

and it is modular—users can grow 

a few plants, or hundreds. With the 

VeggieWall, people can grow veggies 

indoors year-round. The systems are 

affordable to buy and run with their 

energy-efficient LED grow lights. No 

expensive seed cartridges are required. 

We wanted to empower people to grow 

food so we didn’t want to limit how 

they could use their systems. We do 

sell organic and heirloom seeds that 

we have found to work well in the 

VeggieWall, but people are free to use 

their own, too. 

WHAT ELSE MAKES IT UNIQUE? 

The VeggieWall is the world’s first highwater 

flow vertical hydroponic system, 

and it is modular. We have patents 

pending in the USA and Canada for 

our Nutrient Cascade Technology. 

We found that current hydroponic 

watering systems were not adequate 

for what we wanted to do, so we 

invented our own. 

WHAT SHOULD THE NOVICE 

HOME GARDENER KNOW 

ABOUT YOUR PRODUCTS? 

Our technology is your green 

thumb! We have customers who 

have never grown plants before and 

they find it easy. The VeggieWall is 

perfect for urban dwellers who don’t 

have the time, space, or know-how to 

grow food. We also have customers 

who are renovating their kitchens and 

incorporating VeggieWalls into them. 

WHERE DO YOU SEE THE 

COMPANY IN 10 YEARS? 

Currently we can ship anywhere 

in North America and are hoping 

to expand to Europe, Asia, and 

Australia. We hope to use some of 

our profits to provide VeggieWalls 

to families and communities that 

cannot afford fresh, organic food. 

I grew up in a home with a single 

mom and brother and know the 

pains of putting healthy food on the 

table. Matt and I hope products like 

ours will lessen the burden on the 

Earth to feed our increasing population, 

put food back in the hands of 

the people, and reduce pesticides, 

water shortages, and greenhouse 

gas emissions associated with traditional 

agriculture. In short, we hope 

to change the world!

GROWING IN THE 21 ST CENTURY: 

INTRODUCING 

HydroGarden’s Stephen Fry and Refarming’s Jules Bagnoli with the VydroFarm. 

THE VYDROFARM 

HydroGarden, a UK-based supplier of innovative hydroponic gardening 

supplies, has turned a new leaf in sustainable agriculture with the 

VydroFarm, an innovative, fully controllable vertical farming system that 

can be customized to fit almost any space. Stephen Fry, HydroGarden’s 

commercial sales manager, shows us how it works, and where some of 

these systems can be found. 

The future of growing and how to feed 

rapidly increasing world populations 

is a hot topic around the globe. Food 

security is now a major concern for a 

number of countries in the developed 

world. With an estimated 50 per cent 

increase in food demands as the world 

population increases from seven 

to nine billion by 2050, thoughts of 

the future inspired HydroGarden, a 

market-leading supplier of specialist 

hydroponic equipment, to develop a 

solution: the VydroFarm. 

The VydroFarm is a fully controllable, 

vertical farming system that can be 

tailored to fit any space, whether you 

are rooftop gardening in Canada, 

growing in a warehouse in Hong Kong, 

or working on a space station. It features 

vertical racks on tracks that can be 

moved together to maximize production 

density and enable easier harvesting. 

With its market-leading AutoGrow 

MultiGrow systems, the VydroFarm can 

be monitored and controlled remotely 

via smartphone, tablet, or PC, and 

optimal lighting conditions for crop 

growth are achieved with Valoya LED 

lights, reducing the growing time of a 

consistent crop of lettuce to just 28 days. 

On top of the ability to customize it 

to fit a wide range of different spaces, 

the VydroFarm uses 90 per cent 

less water than conventional soiland 

field-grown crops, with no 

water table contamination and 

near-zero food miles to the plate. 

No pesticides are required for food 

production and minimal chemical 

inputs are required, offering a more 

environmentally friendly solution to 

urban food production. 

What also makes the VydroFarm 

stand out is that it doesn’t require 

a highly qualified horticulturalist 

to run the system, says Stephen 

Fry, commercial sales manager for 

HydroGarden. “The VydroFarm is 

scalable, modular, and easily erected,” 

he adds. “It can consistently achieve 

28-day production from the seedling 

stage, and the rack heights and 

lighting rigs are adjustable to suit 

different crops.” 

The VydroFarm 

uses 90 per cent less 

water than conventional 

soil- and field-grown 

crops, with no water 

table contamination and 

near-zero food miles to 

the plate.” 


The VydroFarm is featured in 

a number of innovative growing 

experiments, restaurants, schools 

and even a coffee shop. Two of 

them are installed in the University 

of Nottingham’s Creative Energy 

Homes Project—seven specially 

built eco houses that are being used 

to investigate the integration of 

energy-efficient technologies into 

houses. University researchers are 

using the VydroFarms to look at the 

differences in the energy consumed 

by a hydroponic system using only 

LED lighting, and one that uses a 

mixture of natural and artificial 

lighting sources. “We see this as part 

of a potential solution for ensuring 

global food security in a world with an 

expanding population and increased 

pressures on land use and resources,” 

says Professor Mark Gillott. 

Over at Peterborough Regional 

College in Peterborough, a VydroFarm 

is growing food for the college’s 

on-site restaurant, reducing the food 

miles of some of the ingredients used 

in the restaurant to zero. “Using the 

VydroFarm in a catering environment 

is just one of the applications through 

which it could make a significant 

contribution to providing sustainable 

solutions for future food production,” 

says Stephen. “Not only will it save on 

ingredient costs and delivery, but it can 

also become an exciting talking point, 

setting restaurants apart in a highly 

competitive market. The ingredients 

will also be much fresher than those 

brought in, as they can be harvested 

on-site as required.” 

Home of Honest Coffee in Salford, 

Greater Manchester, has a VydroFarm 

system in its basement, which is 

growing salad greens and herbs. 

The system is maintained by 

Refarming, an organization that 

works with ex-offenders during their 

rehabilitation process, training and 

supporting them in the creation of 

micro-farms and supplying produce. 

“It’s the first commercially available, 

plug-and-play hydroponic farm that 

runs off the same electricity as a 

small domestic appliance,” says Jules 

Bagnoli, founder of Refarming, on why 

she chose the VydroFarm. 

Finally, the University of Liverpool 

is using two VydroFarms to educate 

school children in Liverpool on 

sustainable food production issues. 

The University and Farm Urban, 

a group of bio-scientists at the 

university focused on developing 

and implementing efficient, 

technologically advanced urban 

farms, have incorporated the systems 

into several interactive displays to 

demonstrate the future of farming. 

“We have searched for demonstrator 

and research systems and VydroFarm 

is, in our opinion, the best, most 

cost-effective solution available,” 

explains Iain Young, of the Institute 

of Integrative Biology and Institute of 

Risk and Uncertainty at the University 

of Liverpool. 

The above are just a few 

examples of the VydroFarm in 

action. To get your own VydroFarm 

project going in Canada, email 

stephen.f@hydrogarden.co.uk. 

WHY DO WE NEED TO 

FARM VERTICALLY? 

Dickinson Despommier, an emeritus 

professor of microbiology and 

public health at Columbia University, 

wrote in his book, The Vertical 

Farm: Feeding the World in the 21st 

Century: “It has been estimated that 

the global population will expand by 

three billion people by 2050 and that 

80 per cent of the Earth’s population 

will live in urban centres. With these 

statistics, it would require an area 

about 20 per cent more than the 

size of Brazil to grow enough food 

to feed them, if traditional farming 

practices continue as they are today.” 

HydroGarden believes vertical farming 

is the solution and that the VydroFarm 

can help meet future food 

demands. It will allow countries with 

undesirable growing conditions to 

produce their own food source and 

provide fresh vegetables locally all 

year. A completely controlled growing 

environment means that growing 

can take place in warm or cold climates, 

24 hours a day. And beyond 

this planet, increasingly lengthy 

space missions mean that scientists 

are investing huge resources in 

finding ways for astronauts to grow 

their own food, both in space and 

on faraway planets. The answer is 

hydroponics and, more specifically, 

vertical farming.
