No matter what technology we use to grow, how plants
grow will never change. The basic biology remains
constant, as do the problems growers encounter,
such as pests, nutrient deficiency, and pH control.”
from the
EDITOR
TG
Toby Gorman
We’re returning briefly to our roots in
this issue of Maximum Yield. Over
the past couple of years, we’ve focused
on the innovation that has taken place in
the indoor growing space. There has been
a lot. From robotic bees to personal food
computers, artificial intelligence to growing
hydroponically in space, how we grow our
food is constantly changing. These days,
indoor farms that employ just a couple of
robots and a cloud-based brain are at the
leading edge of farming.
No matter what technology we use to grow,
how plants grow will never change. The
basic biology remains constant, as do the
problems growers encounter, such as pests,
nutrient deficiency, and pH control.
This month, we’re featuring stories that
every grower needs to know, starting with
long-time contributor Monica Mansfield’s
“Hydro Nutrient Management: What Every
Grower Should Know” on page 40. As Monica
states, “You are taking on nature’s role
and are responsible for putting together
the correct nutrients, in the right amounts,
with the right pH, at the right time. You
must also manage your water’s quality
more strictly and be aware of any chemical
incompatibilities that could hurt your plants.”
Of course, before you establish plants
inside, it’s essential to have your grow space
clean and disinfected to prevent heartbreak
down the road. For tips on keeping your grow
space as clean as can be, check out Alan
Ray’s tips in “The Importance of Growroom
Hygiene” on page 60.
“Growing indoors definitely holds some
advantages over traditional outdoor patches
when it comes to weather and varmints, but
it also comes with its own set of issues and
enemies,” says Alan.
Finally, Philip McIntosh’s “Maintaining and
Troubleshooting pH Control Systems” on
page 44 identifies what can go wrong with a
pH control system. For growers employing a
control system, it’s a must read.

Parts Per Million (PPM) and Electrical Conductivity (EC)
Parts per million (PPM) and Electrical conductivity (EC) are both measurements
of the total dissolved salts in your solution.
EC is the measurement of a solution’s ability to conduct an electrical charge. Pure
water (H 2O with nothing dissolved in it) does not conduct electricity. The higher the
solution’s salt concentration, the better it conducts electricity. A grower can easily
measure EC with an EC meter. While this measurement will not tell you exactly how
much nitrogen, phosphorus, or potassium is in your solution, it will give you an idea
of the overall nutrient concentration. You can use this number to add nutrients to a
recirculating system in between reservoir changes. Most feeding schedules will tell
you what the PPM or EC should be at each week’s stage of growth.

GROWER
Q
What would be the best way to plant a sprouting seed in aquaponics?
Mesh pot with stonewool? Or just clay pebbles surround the seedling?
Thanks,
Toefur
a
Hi Toefur,
Great question! I take it to mean that you have a seed
that has already germinated and is ready for transplant
into your system versus successfully sprouting
a seed that is directly sown into the media. The “easy”
answer is that if you have a healthy seedling and a
clean system, you should be able to plant your sprout
into any of the media that you have mentioned.
I personally prefer stonewool for starting out
plants for hydroponics (both for direct seeding and
transplanting), because I like the support the plant
gets before it has fully rooted out and can support
itself. Many growers have luck directly sowing into
clay pebbles, but unless you do this routinely or until
you have enough practice setting the transplants
in without damaging the roots, I would suggest
wrapping a small wad of paper towel or other
absorbent material, even a wad of cotton, to help hold
the seedling in place until it roots into its new home.
Don’t be alarmed if there is a delay in noting any
growth for even a few weeks while your transplant
adapts to its new home, so long as everything else
is in balance (light, temperature, pH, and electrical
conductivity). If you are, however, looking for quicker
turnarounds, such as for commercial production,
direct sowing will usually reduce the time from seed
to harvest. If you are just starting out or are a hobby
grower, starting with transplants is a good way to get
your “feet wet,” or rather, your plants’ roots wet.
Best of luck!

FACTS
Harnessing Genetic Resistance in Beans to Battle Weevils
Weevils, a small beetle, can infest beans in the field or in storage, leading to
massive loss of bean crops. Developing bean varieties that are resistant to weevils
is a long-term solution for researcher Kelvin Kamfwa, a University of Zambia bean
breeder who authored a study that narrowed down the genetic locations of several
weevil-resistant genes in common beans. Kamfwa confirmed weevil resistance in
beans is genetic and can be transferred to bean plants with different seed types
and colors. “This will allow breeders in different countries to introduce weevil
resistance into bean varieties adapted to local conditions,” says Kamfwa. His
research also shows that weevil resistance is inherited separately from seed size
in beans. Earlier studies suggested a relationship between weevil resistance and
seed size. If true, that would prevent plant breeders from developing larger-seeded
beans with weevil resistance. Bean varieties resistant to weevils can help farmers in
the field and when it’s time to store harvests.

Study Shows Manure Improves Soil Quality Compared to Fertilizer
A 12-year study has concluded long-term yearly application of manure improved
most soil quality properties compared with an inorganic fertilizer. A
research team from the University of Wisconsin-Madison conducted the
study in South Dakota. Soil samples were collected at various depths
using a push probe auger. The analyzed samples showed manure
helped soil maintain a healthy pH for crops, while inorganic
fertilizer made the soil more acidic. Manure boosted soil organic
carbon at all measured depths compared to fertilizer. Manure
also significantly increased total nitrogen (which is key for
plant growth) compared with fertilizer. Additionally, manure
boosted water-stable aggregates (groups of soil particles that
stick to each other, while inorganic fertilizer decreased these
aggregates. On the negative side, manure did increase the
electrical conductivity in soil which means higher salt levels. The
takeaway from this study for the backyard gardener is composted
manure is the way to go for healthy soil, plants, and vegetables.

Symbiotic Relationship Helps Crops Thrive in Drought-stricken Africa
A companion plant in food-insecure parts of West Africa has proven to be a huge
boon for millet production. A study published in Frontiers in Environmental Science
showed a 900 per cent increase in millet (a grain crop) production after growing it
beside woody shrubs (notably Guiera). The shrubs are able to share the scarce water
they draw in and boost production of millet, a primary grain in providing nutrition
to West Africans. “People in this part of Africa rely on locally grown crops to survive.
Finding ways to increase food production, especially during times of severe drought,
is critical,” says Richard Dick, a professor of soil microbial ecology at Ohio State, who
helped conduct the study. Dick developed a system to optimize Guiera with millet
that increases shrub density in farmers’ fields from less than 300 shrubs per 2.5 acres
to 1,500 shrubs. Along with better yields, the system improves soil quality, boosts
crop nutrients, and reduces harvest time.

FACTS
Research Shows Mycorrhizal Fungi Not Always Beneficial
Many horticulturalists know the beneficial relationship between arbuscular
mycorrhizal fungi (AMF) and crop and plant roots. However, research by
ecologist Adam Frew published in Soil Biology and Biochemistery shows
that in some cases, these fungi can harm crops. Many companies sell AMF as
biofertilizers but the effects of these products are highly variable and there
is little proof they are necessarily beneficial in every situation, according to
Frew. The research shows different species of fungi on the growth of wheat and
its resistance to plant-parasitic nematodes that attack the roots. Frew found fungal
inoculation actually reduced plant growth and suppressed important defence-related
compounds in the roots. He also observed an increase in nematode populations in the soil,
potentially due to lowered plant defences. Frew notes the study was not done in the field and
more research needs to be done to properly understand the relationship between AMF and crops.

Chocolate First Consumed Far Earlier Than Originally Thought
A new study shows the cacao plant — from which chocolate is made — was grown for food
and drink some 1,500 years earlier than previously thought. Published in Nature Ecology
& Evolution, the research found cacao was first domesticated in South America, not
Central America. “This new study shows us that people in the upper reaches of
the Amazon basin, extending up into the foothills of the Andes in southeastern
Ecuador, were harvesting and consuming cacao that appears to be a close
relative of the type of cacao later used in Mexico — and they were doing
this 1,500 years earlier,” said Michael Blake, study co-author and
professor in the University of British Columbia department of
anthropology. Evidence to show the Mayo-Chinchipe culture
used cacao between 5,300 and 2,100 years ago includes the
presence of starch grains specific to the cacao tree inside
ceramic vessels and broken pieces of pottery.

Could Rising CO 2 Levels Trigger More Mosquito-related Diseases?
There is concern that as CO 2 levels rise as a result of human activity, so too will the
diversity of disease-carrying mosquitos. Female mosquitos can identify sources
of blood-meal from the CO 2 levels that mammals release from their bodies. A new
study shows for the first time the impact climate change is having on the rate in
which mosquitos diversify, and what this mean for human health in the future. Study
participant Dr. Katie Davis, from the University of York’s Department of Biology, says:
“We constructed an evolutionary tree of mosquito species, and then mapped it
against past climate change. We then used a mathematical model to look at direct
cause and effect, which revealed that rising CO 2 levels over time has increased
species of mosquito. With increased speciation, however, comes the added
risk of disease increase and the return of certain diseases in countries that had
eradicated them or never experienced them before.”

Study Finds Liverwort Weed Contains
Painkiller Similar to THC
An interesting discovery shows liverwort, a small, mosslike
plant, contains a compound with similar structure to
tetrahydrocannabinol (THC) in cannabis plants. The molecule,
called perrotetinene, was tested with both mice and human
brain cells. Researchers reported in Science Advance that
perrotetinene, like THC, attaches to the brain’s cannabinoid
receptors and dampens pain signal effects without the high
of THC. In 1994, a group of Japanese scientists discovered
perrotetinene in liverworts, but the new study is the strongest
evidence yet that the compound is a psychoactive cannabinoid.
So far, only three species of liverwort in the Radula genus — found
in Japan, Costa Rica, New Zealand, and Tasmania — are known to
produce the compound. Tests on mice showed perrotetinene may
be slightly less psychoactive than THC and may also have fewer
negative side effects like memory loss and
loss of coordination. Liverwort generally
grows as a common weed.

Plant Hormone Could Make Growing
Veggies in Space a Reality
With minimal nutrients and weak gravity, growing carrots on the
moon or other planets seems impossible. But the plant hormone
strigolactone could make it possible, biologists from the University
of Zurich have shown. Strigolactone supports the symbiosis
between fungi and plant roots, thus encouraging plant growth. In
looking for a means to grow on other planets, the research group
focused on the process of mycorrhiza, a symbiotic association
between fungi and plant roots where the fungal hyphae supply
plant roots with additional water, nitrogen, phosphates, and
trace elements from the ground. In return they get access to
sugar and fat produced by the plant. This symbiosis is stimulated
by strigolactone hormones, which most plants secrete into the
soil around their roots. Interestingly, strigolactone functions in
microgravity and plants were able to thrive
in low-nutrient soil despite the harsh
microgravity conditions.

UNDERSTANDING AND USING
NUTRIENT
FILM
TECHNIQUE
HYDROPONIC SYSTEMS
by Dr. Lynette Morgan
Developed more than 50 years ago, NFT systems
can quickly produce large yields of produce with
minimum water usage. However, these systems can
present problems — for both home and commercial
growers — if they aren’t monitored properly.
32
Maximum Yield

Nutrient film technique (NFT) was the world’s first method
of crop production that didn’t use a solid rooting
medium. Developed in the 1960s by Dr. Allen Cooper at
the Glasshouse Crops Research Institute in England, the
system was initially met with skepticism until studies
proved NFT was not only viable but had considerable
potential for many crops. Nowadays, NFT systems have
gained worldwide acceptance, mostly in producing
small-framed, rapid-turnover crops such as lettuce, herbs,
strawberries, green vegetables, fodder, and micro greens,
although longer-term plants like tomatoes will grow in
these systems in larger channel sizes. NFT allows for
producing ‘living greens’ crops — those harvested and sold
with roots intact and wrapped in plastic sleeves to prolong
shelf life post harvest. NFT, being a solution culture
method, often captures the imagination of many indoor and
hobby gardeners, as well as those planning a commercial
venture as a method of growing plants with minimal
requirements with efficient water usage. However, NFT is
a system that needs to be well understood for maximum
growth rates and yields with minimal problems.
THE PRINCIPLES OF NFT
As the name suggests, NFT is a system of solution culture
where a thin film (a quarter inch depth) continually flows
along the base of small channels in which the root systems
sit. Channels are often constructed of rigid materials
such as high-density polyethylene, specifically designed
and manufactured for hydroponic crop production, or
formed from thick plastic film which is folded up to form
a triangular shaped channel. With NFT, the objective is
that part of the developing root mat is in the nutrient flow,
but many of the other roots are sitting up above this in the
moist air, accessing oxygen without being submerged.
Seedlings or young plants in NFT are typically supported
by either propagation cubes of stonewool, oasis or coconut
fiber, or in small lattice pots which slot into the top surface
of the growing channels. A central nutrient reservoir holds
the nutrient solution and from there it is pumped up into
the growing channels, flows past the root systems, and is
piped back to the reservoir for monitoring and adjustment
either manually or automatically via electronic doser units.
Maximum Yield 33

One of the main advantages of NFT, apart from the cost and labor savings of not
requiring large volumes of a growing substrate, is it allows production of salad greens,
lettuce, and herbs without the risk of grit contamination which can occur in soilless
substrate systems. NFT systems may incorporate heating or cooling of the nutrient solution
as is required for year-round cropping and allow a very ‘clean’ system to be run,
with sterilization of equipment between crops if necessary.
The main disadvantage of NFT is that power outages, which halt the continual flow of
nutrient, can quickly result in crop death, particularly under warm growing conditions.
Top: Multi-level NFT systems maximize
growing space.
Bottom: Vertical systems are ideal for
lightweight NFT channels.
“NFT systems may seem more complex
than substrate-based types of hydroponics,
however, they are extremely flexible with
regards to size, design, and equipment.”
FLEXIBILITY OF NFT SYSTEMS
NFT systems may seem more complex than substrate-based types of hydroponics,
however, they are extremely flexible with regards to size, design, and equipment.
A small basic system can comprise a single growing channel for production of a
few plants, a plastic bucket or bin for a nutrient reservoir, and a small aquarium
pump to circulate the nutrient solution. NFT growing
channels with a flat base profile can be purchased, however,
over the decades many innovative materials have been
used where these are not available. These include rainwater
down pipes, large diameter bamboo, channels formed from
timber, metal, or concrete and lined with plastic and long
rolls of plastic film itself folded into channels. These types of
basic NFT systems require manual checking and adjustment
of the electrical conductivity (EC) and pH of the nutrient
solution, and regular water level adjustments.
Commercial NFT systems are typically far more automated
than hobby systems and make use of electronic and
computer-controlled EC, pH adjustment, and float valves to
replace water used in the system. Advanced commercial
NFT systems may also utilize dissolved oxygen and solution
temperature measurements to monitor these root zone
variables. An NFT-based growing operation often has both
seedling and finishing NFT benches through which the plants
progress during production. Seedling systems have plants at
a much higher density, which are moved to a wider spacing
in the finishing system to maximize the growing area inside
greenhouses. Other NFT systems include moveable channel
systems where the distance between adjacent channels is
increased as the plants grow. Vertical NFT systems are also
popular and optimize growing space for lower-light crops
such as lettuce and some herbs. NFT systems can also be
installed outdoors or under basic shade covers.
IMPORTANT NFT FACTORS TO CONSIDER
Constructing and running a successful NFT system is reliant
on a few vital factors. These include slope, flow rate, nutrient
reservoir size, channel volume, and pump capacity. For those
purchasing an NFT system kitset, choose a reliable supplier with
a good reputation and these variables will already have been
factored into the design. For home-built systems, some consideration
needs to be given to all components and equipment. The
channels must be positioned on a slope so the nutrient solution flows steadily down at
a good flow rate, which for most systems is around 0.26 gallons/minute. Some systems
allow the channel slope to be adjusted and increased as the root system develops and
expands inside the channels, ensuring nutrient ponding does not occur. The dimensions
of the NFT channels are dependant on the type of plants being grown. Small
lettuce and herbs may be grown in standard NFT channels of four inches wide and two
inches high made from UV stabilized FDA approved high density polyethylene. Larger
plants like cucumbers and tomatoes require a wider and taller channel to accommodate
their considerably larger root system.
34
Maximum Yield

Reservoir size is also important and many smaller NFT systems are set up with
undersized nutrient tanks. A buffer capacity volume of at least 50 per cent is a good
rule when selecting a reservoir. This means when all the channels are carrying
nutrient solution at the desired depth, sufficient nutrient remains in the tank to half
fill it or the tank is large enough to hold twice the amount of nutrient in the gullies.
This is considered a minimum and many systems have larger tanks than this,
as a greater volume slows the rate of change in EC, pH, and temperature in the
reservoir nutrient solution.
“NFT is a system that needs to be well
understood for maximum growth rates
and yields with minimal problems.”
Top: Larger NFT channels can be used to
produce fruiting crops such as tomatoes.
Bottom: An NFT garden can provide a
surprising volume and variety of fresh greens.
NFT pumps are pieces of equipment that are often misjudged and don’t provide
the capacity required. Not only is it important to consider the capacity of the pump
in terms of liters or gallons per hour, but also the head height which is the pump’s
ability to move nutrient solution up to a certain height (i.e. the top of the NFT system).
Most NFT systems use centrifugal pumps capable of producing constant flow of
nutrient solution. These pumps will either pump a small volume of nutrient solution
to a high head, or a large volume of nutrient to a low head
height. In between the two extremes the characteristics of the
pump will vary and ‘pump performance’ curves should be used
to select the pump with the correct head height verses flow rate
characteristics for a particular NFT system.
MANAGING NFT NUTRIENT SOLUTIONS
NFT systems continually recirculate nutrient solution, thus
they are more prone to nutrient imbalances, build up of
unwanted elements, and changes in nutrient ratios over time
as compared to ‘drain to waste’ substrate-based systems.
For this reason, a high-quality, low-mineral water supply
is required that doesn’t contain high levels of unwanted
elements, like sodium, which may accumulate over time.
Where plant-usable elements such as calcium, magnesium,
and some trace elements are present in the water supply,
these can be adjusted with a customized nutrient solution.
A build-up of unwanted minerals or a significant change
in the nutrient balance over time requires the NFT solution
to be regularly changed either partially or completely to
maintain good growth rates. NFT systems also require regular
monitoring and adjustment of pH and EC as changes in these
can occur rapidly with some crops. For smaller systems,
once-daily checking and adjustment is usually sufficient for
manually monitored systems. For systems automatically
adjusting EC and pH, the system still requires occasional
manual checks as a backup to equipment failures and errors.
POTENTIAL PROBLEMS
NFT systems, like all hydroponic methods, are not without their
potential problems. While disease outbreaks do sometimes
occur in NFT, as they can in all hydroponic systems, careful
management and following the principals of NFT with a high
rate of oxygenation, minimal flow depth, and solution temperature
control all assist with minimizing these issues. An area
of increasing research and understanding with NFT, particularly
with the relatively new development of organic NFT systems, is the role that
microbial populations, present in the root system, growing channels, and nutrient
solutions, play in disease prevention and crop health. Beneficial microbes develop in
NFT systems just like in soil and soilless substrates. Growers may choose to increase
these microbes via slow sand filtration or the use of inoculant products.

“Beneficial microbes develop in NFT systems
just like in soil and soilless substrates.”
NFT systems are well-suited to herb production
with basil being the most commonly grown crop.
Nutrient management is also an area of potential problems
as it is possible for a rapidly growing crop to strip
out an essential element from the recirculating system
(often nitrogen or potassium) faster then it is being replenished
via stock solution additions. Use of nutrient solution
analysis is a common practice with commercial growers;
it allows rapid adjustment of the recirculating solution
as required so imbalances are prevented. Growth may
be slowed when NFT solutions start to get out of balance
and may go unnoticed until a severe and visible deficiency
becomes obvious, so being proactive with solution
monitoring and adjustment for larger growers is also
recommended. Smaller growers who don’t want to pay
for solution analysis testing can simply carry out regular
partial or complete solution changes to ensure all nutrient
elements remain in balance.
NFT is a great learning tool for students and inexperienced growers as it
allows the root system to be viewed as plants develop and allows for gaining
skills in nutrient control and running an efficient system. While NFT can seem
complicated with the equipment required, a basic system can be easy and quick
to set up with the added benefit of not requiring large volumes of substrate to be
regularly brought in and disposed of.

Nutrient Management
What Every Grower
Should Know
by Monica Mansfield
When you choose to
grow hydroponically,
it becomes your
responsibility to ensure
your plants are receiving
what they need to be
healthy and productive.
Follow Monica Mansfield’s
tips and your plants will
think Mother Nature is
working her magic.
One of the keys to a successful
hydroponic garden is having
a solid nutrient management
plan. Plants grown hydroponically
are much more sensitive
to the nutrients you give them
simply because they don’t
have the soil to buffer any
mistakes you may make.
You are taking on nature’s role
and are responsible for putting
together the correct nutrients, in
the right amounts, with the right
pH, at the right time. You must
also manage your water’s quality
more strictly and be aware of any
chemical incompatibilities that
could hurt your plants.
40
Maximum Yield

“Too much
nitrogen
can cause extremely
green leaves, excessive
vegetative growth,
and reduced fruiting.”
Essential Nutrients
First things first, you must understand the importance of
the nutrients you are feeding your plants. They can be
broken down into three categories: primary, secondary,
and micronutrients. In hydroponics, instead of receiving
these nutrients from the soil, plants get these nutrients
from the nutrient solution they grow in.
Primary nutrients include nitrogen, phosphorus, and
potassium. These are needed in large quantities for
plants to thrive. The secondary nutrients are calcium,
magnesium, and sulfur. They are needed in smaller
quantities than the primary nutrients, but in much
larger amounts than the micronutrients. Micronutrients
include iron, molybdenum, boron, copper, manganese,
sodium, zinc, nickel, chlorine, cobalt, aluminum, silicon,
vanadium, and selenium. Plants also need carbon,
hydrogen, and oxygen, however, they receive these
from the air and water.
If a plant takes in too much or too little of these nutrients,
they will suffer from deficiencies or toxicities. Plants
will show signs to help you figure out what they need. For
example, a nitrogen deficiency will cause yellowing of
the older leaves and slowed growth. Too much nitrogen
can cause extremely green leaves, excessive vegetative
growth, and reduced fruiting.
Understanding Ratios and Formulas
When you go into a hydroponic shop, it is easy to be
overwhelmed by the hundreds of fertilizers lining the
shelves. There are many different formulas and ratios
to choose from.
There will be three numbers on the front of the fertilizer
bottles. This is the NPK, which stands for nitrogen,
phosphorus, and potassium, respectively. These numbers
represent the percentage of each nutrient in the bottle.
A 7-9-5 fertilizer will have seven per cent nitrogen, nine
per cent phosphorus, and five per cent potassium in that
bottle. The back label will tell you the percentage of other
nutrients in the fertilizer.
These ratios will vary a little by brand, what kind of
formula it is, and what stage of growth it is meant for.
Fertilizers formulated for the growth stage of plant development
will have more nitrogen, while the bloom stage
formulas will have less nitrogen and more phosphorus.
You will also see one-part, two-part, and three-part
formulas. One-part formulas have one bottle for the
growth stage and one bottle for the bloom stage of growth.
While they contain all the nutrients needed, they likely
have smaller amounts of calcium to keep the formula
stable and will need to be supplemented. One-part formulas
are ideal for beginners who don’t yet understand how
to adjust recipes for their plant’s specific needs.
Two-part formulas have an A and B formula for growth,
and an A and B formula for bloom. By separating some
of the chemicals, the manufacturer has created a more
stable and complete formula that can be mixed at different
rates throughout the growth cycle. Specifically, higher
amounts of calcium and phosphorus can be included in
the base nutrients by separating them instead of putting
them together in one bottle.
Three-part formulas include a separate grow, bloom,
and micro formula that will be mixed together at
different ratios throughout a plant’s life. This allows
for much more flexibility so that the grower can tailor
nutrient recipes to their plant’s specific needs and fix
deficiencies more quickly.

Water
One of the most important things to consider in a
hydroponic nutrient management program is your
water. It is essential to test your water before designing
your program. You will want to test for alkalinity,
electrical conductivity (EC), and contaminants.
Alkalinity is measured from near zero to more than
300 parts per million (PPM). If your water’s alkalinity
is high, then the pH will tend to rise in your nutrient
solution. Ideally, you want your alkalinity as close to
zero as possible, as it is in reverse osmosis-treated
water. It is important to note that alkalinity is not
the same as pH. While pH can be measured at a
certain point in time, alkalinity is a measure of your
water’s longer-lasting pH effect. Knowing your water’s
alkalinity can help you choose the proper
fertilizer program. For example, you may want
to use a fertilizer with greater amounts of acidic
nitrogen to counter the pH rise.
Your water's EC can be a rough measurement
of your water’s purity. Electrical conductivity
measures the total dissolved salts in your water.
If your EC is high, then you will want to use a
drain-to-waste hydroponic system. Electrical
conductivity should be low, ideally less than
0.25 mS/cm for closed systems. You can also filter
your water using reverse osmosis if you would
like to use a closed system but have a high EC.
Your lab analysis should tell you what other
elements or contaminants are already present in
your water. This is helpful when designing your
fertilizer program. For example, if your water
already has calcium or magnesium then you
will not have to add as much to your nutrient
solution. If your water has high levels of sodium
or chloride, you know that you may need to
purify your water or flush your soil more often to
prevent salt build-up.
To adjust your pH, you will add acids and bases to your
nutrient solution. Add a little at a time and measure with
your meter as you go. Common acids used to decrease
pH include sulfuric acid, phosphoric acid, citric acid, and
nitric acid. To increase your pH, potassium hydroxide
and sodium hydroxide are commonly used. It is important
to consider which acids and bases you use to adjust
your pH, as they will add nutrients to your solution. For
example, nitric acid will add nitrogen and phosphoric
acid will add phosphorus.
“One of the most
important things
to consider in a hydroponic nutrient
management program is your water.”
pH
Monitoring and maintaining a proper pH is
crucial in a hydroponics nutrient management
system. The solution’s pH measures how acidic
or basic it is. The scale ranges from zero to 14,
with 7.0 being neutral. Different nutrients are
available at different pH levels. In general,
nutrient solutions for hydroponics should have
a pH between 5.0 and 6.0, which will create a
pH in the root environment of between 6.0 and
6.5. In this range, more nutrients are readily
available to plants.
You can measure pH with either pH strips
or a pH meter. If you use a meter, be sure to
calibrate it on a regular basis, about once
every week or two.
Depending on your hydroponic system and your
plant’s stage of growth, you may need to adjust
your pH often. A drain-to-waste system does not
reuse water, so you will adjust your pH when you
mix it initially. However, recirculating systems
will need more frequent adjustments. As roots
respire, the pH will decrease as carbon dioxide
reacts with water to create carbonic acid. This
will happen much more towards harvest when
roots are their largest.

“Although you can
simply follow
the measurements on the
bottle, your solution will be
more precise if you mix it using
a PPM or EC meter.”
PPM/EC
When mixing your nutrient solution, you have the option
of creating your own program from scratch or following
a pre-designed program from a fertilizer company.
Commercial operations usually design their program
from scratch so that they can adjust their solution as
needed. To save money, many commercial operations use
recirculating systems and lab-test their nutrient solution
regularly so they can add only the elements that have
been depleted. For the hobby grower, however, it is much
easier to follow a feeding plan that has been designed
by a fertilizer company. Most companies have feeding
schedules available to go with their products.
Although you can simply follow the measurements on
the bottle, your solution will be more precise if you mix it
using a PPM or EC meter. Parts per million and EC both
measure the total dissolved salts in your solution. While
this measurement will not tell you exactly how much
nitrogen, phosphorus, or potassium is in your solution, it
will give you an idea of the overall nutrient concentration.
You can use this number to add nutrients to a recirculating
system in between reservoir changes. Most feeding
schedules will tell you what the PPM or EC should be at
each week’s stage of growth.
If you are a hydro grower, follow these principles to
create an effective nutrient management plan for a
successful harvest.

“The bottom line is controlling the pH of a nutrient solution
is of prime importance if one wants best results.”
T
he chemical makeup of a nutrient
solution is a critical factor in the
success of any hydroponic installation.
The nutrient element concentrations
and the acid-base chemistry of the
solution should be well controlled. This
is needed for several reasons: optimum
conditions for plants, lowest cost, and
minimized waste.
The acidity of any nutrient solution
is a critical parameter. Too much acid
(low pH) and the roots will get damaged
and may even leak cytoplasm into
the nutrient solution. If the low pH
persists, the plants will wilt and die.
Not enough acid (high pH) and nutrients
may not be as available for uptake by
plants. Of course, a very high pH will
also severely damage plant roots. The
bottom line is controlling the pH of a
nutrient solution is of prime importance
if one wants best results.
It is possible to manually test and
adjust the pH of
a nutrient solution.
Often, this is
how small or prototype
systems are
initially set up. If the
pH is tested several
times per day (at least once is recommended)
and an adjusting solution
added accordingly, this is generally
an adequate approach. However,
medium-sized and larger commercial
operations invariably use (or should
use) automated pH control systems.
Although automated systems reduce
labor and, when operating well, give
the grower one less thing to worry about
day to day, they can, and do, present
problems. This article is concerned with
those systems that include a measuring
component and a dosing component to
automatically control the solution pH in
a nutrient reservoir.
Loss of pH control can be caused by
many defects, but usually is either
caused by the pH sensing part of the
system, or the pH adjusting part of the
system. Incorrect instrument readings
can result in improper operation of the
adjusting system, even though there
is nothing wrong with the adjusting
hardware or software. On the other
hand, if the adjusting solution is not
well controlled, the system can be
unstable with wider-than-desired fluctuations
in the pH. Not all malfunctions
fit neatly into either of these two possible
failure modes, but many do, and
they provide a good starting place for
troubleshooting procedures.
46
Maximum Yield

Troubleshooting pH Control Systems
When troubleshooting a pH control system, no matter what the
problem is, it usually pays to go through a few simple checks
before getting too far involved, just to make sure there is not a
simple solution. Do the following first:
1. Confirm that any circuit protection devices are not tripped
and make sure there is electrical power to the system.
2. Check all electrical connectors for tightness. Look for
damaged wiring.
3. Check all plumbing fittings for tightness, breaks, or leakage.
4. Check the location of the pH electrode. Make sure it hasn’t
come loose.
5. Check the supply of adjusting chemicals (acid and/or base)
to make sure they haven’t run out and that they are the
correct concentration.
These checks should take only a minute or two. How many
times in the world will something not work only because it’s
not plugged in or the power switch is turned off? Many, many
times, to be sure.
Calibration
To calibrate simply means to check a measuring device
against a standard to determine its accuracy and precision.
Contrary to popular belief, it does not mean “adjust the
system” to improve its performance, although that is often
done. If there is a discrepancy between the measured value
and the true value, if the amount of error is known, it can be
compensated for.
Also, pH controllers are either
of the single-point (tested and
adjusted at one pH value) or
two-point (tested at two pH
values and adjusting one and
the slope between them) calibration
type. Either method works
with two-point preferred for better accuracy
and precision. Calibration solutions should
be fresh (used before their expiration dates) and proper techniques
must be used to avoid cross contamination of solutions
which will slowly degrade the accuracy of the calibrations.
Pumps
Pumps used to inject acid or base into a nutrient tank do not
run continuously so they should last for many years before
failure. Occasionally, a pump may need to be partially
disassembled and cleaned. Most pumps are lubricated for life
but check the manufacturer’s recommendations on that.
Peristaltic pumps are sometimes used for liquid injection.
The internal parts of a peristaltic pump never contact the
fluid itself and use a roller squeezing action on flexible
tubing to move fluid. For these pumps, the tubing should
be moved periodically (if possible, depending on design) to
avoid wearing out the same section of tubing as the pump
does its work. If the tubing cannot be moved, inspect and
replace it before it wears out.
“Pumps used to inject acid or base into a
nutrient tank do not run continuously so they
should last for many years before failure.”
Electrodes
Electrodes, commonly called probes,
submerged in a nutrient solution are
exposed to a relatively harsh chemical
environment of dissolved ions. Solution
constituents can precipitate out of solution
onto the probe, which will degrade probe performance after a
while. Probes should be inspected regularly and cleaned as
needed in accordance with the manufacturer’s recommendations.
Electrodes don’t like to be operated in air, so make sure
the solution level does not drop below the level of the installed
probe. Automatic fluid level control and a low-level warning
system are good ideas. It is not unusual to have to replace an
electrode every few years or so.
48

Electronics
The good news is semiconductor components (transistors
and integrated circuits) have a low failure rate and are
probably the least likely parts of a system to fail. This is
especially true of microprocessors, which are designed to
operate reliably for many years (decades even). If there is to
be a failure in a controller it is most likely to be in the power
supply or electrical connections. Connectors can come loose
or be fouled with contaminants if they are in an exposed
location. Occasionally, an internal relay used to turn the
pump on and off may fail.
Power supplies in controllers do most of the hard work
as far as electronics go. The power supply provides all
the current used by every part of the circuit and generates
the most heat. So, if a controller fails, the power supply
is a good starting point for isolating the problem. Unless
you have good documentation (schematics and circuit
descriptions), it is difficult to make much progress on
troubleshooting an electronic
controller and, in most cases, you
are better off replacing a defective
controller with a new one. High-end
controllers can often be returned to the
factory for repair, but unless you have
a spare unit, your system will be down
for the repair period.
Update the Software
Most pH controllers are not easily
modifiable after purchase and installation.
What you have is what you’ve
got. However, some systems may have
firmware that can be periodically
updated. If the system interfaces with
a PC-based software package for data
display and system control, it is likely
this software will be updated periodically.
If software updates become
available, install them.

No one in charge of pH control wants a

serious defect can be quickly corrected. Systems that interface

Litmus-type pH paper should be on hand in case all else
fails. Test paper can also be used to informally check against
the electronic reading to see if they agree. If they don’t, further
investigation is warranted.

dreaded scenarios imaginable to any horticulturist. Get to

Microorganisms are routinely introduced and cultivated
in our hydroponic setups and gardens, but one such
organism you don’t want to see is Pythium. It’s difficult
to eradicate and it kills everything in its path.
DEALING WITH
Pythium
RootRot
hough previously classified as fungi, Pythium is an
Toomycete and an absorptive, parasitic microorganism.
Pythium feeds on dead or decaying organic matter and is
on the pathway to disease and plant death. Nature has an
assignment for Pythium — to help completely decay and
digest dying organic matter.
Pythium can also be very difficult to control or eradicate, so it
is far better to prevent this organism than it is to cure. Pythium
root rot is a persistent cause of trouble in constantly wet
soil. Root rot multiplies rapidly by producing tiny, spreading
spores. These grow and multiply in the soil or grow media
until all plants in the area are infected. In systems where
water is recirculated to more than one section, the disease
can spread throughout all interconnected areas. Prior to being
able to establish itself, however, Pythium is very selective
about what plants it attacks. This is key toward winning the
battle against Pythium.

HOW PYTHIUM FINDS ITS WAY
INTO THE GARDEN?
Though Pythium is not mentioned in
horticulture literature as a disease
likely to be spread through airborne
means, there are many other root rot
diseases that are. So, in addition to
contamination from containers, tools,
and old soil, airborne contamination
from many other soil diseases is
an issue. This information is very
important in developing a controlmanagement
program to protect your
crop from root rot diseases.
Most often, soil-borne disease
microbes flourish because the soil or
grow media is constantly wet. The
spores leading to an infection capable
of harming your crop have many
avenues from which to come and, with
wet soil, they have the environment to
help these pests thrive.
Fungus gnats are often a source or
vector for Pythium. These tiny insects
thrive in moist soil and lay their eggs
there. Because of this, not only do they
spread their populations throughout
your home or greenhouse this way,
they become contaminated by Pythium
spores (when present) and can easily
spread them to other plants.
Using old potting mixes and recirculating irrigation
water are two common ways Pythium gets introduced to
some of your plants. When water is recirculated through
a common reservoir and even one plant becomes
infected, they are all exposed to these same microbes.
Smaller groups of plants sharing water reservoirs will
help reduce the expanse of crop that may be damaged.
Aeration of the reservoir water will also help reduce the
proliferation of these microbes in your reservoir. Other
contamination sources include garden equipment and
containers or raised bed structures. Even the clothes you
wear into your grow area may be contaminated.
The healthy roots on the plant to the left are key to the healthy foliage seen. The plant to the
right is the most severely diseased, while the one in the center is progressing in severity.
DETECTING PYTHIUM
The effects of Pythium continue beyond the initial plant onto
the developing mature plants long after transplanting. The
symptoms need to be viewed separately from their impact
on plant function. Early symptoms will appear at the stem
base and, if inspected, the roots. Roots will show widespread
browning and new whitish rootlets will be sparse or missing
altogether. Dark lesions often develop on the stem base and
these moist looking spots will likely be your first clue of
an infestation. Damping-off is another clue for identifying
the presence of Pythium. This is seen in young plants and
seedlings, and most often in soilless cultures.

For more information on
various microbial pests
causing root rot disease, scan
the QR code at the end of the article and follow an appropriate
link. Knowing which soil disease is likely causing
the decline of your crop is critical towards knowing how
to attempt control the issue. Please look at the chart for
spotting these causal agents.
PREVENTING PYTHIUM
It is not very practical to physically isolate your crop to try
and prevent pathogen microbes like Pythium. There are
simply too many things that can eventually creep into your
greenhouse or tent to infect the soil or foliage. There are,
however, steps to reduce and minimize your crop’s exposure.
The recommendation for not reusing old potting mix is
primarily focused on prevention of root rot. In the old soil
there are dead roots, which need to decay and go away.
But those roots are an invitation and sustenance for pathogenic
microbes that cause root rot. Soil sterilization, either
through solarization or other high-temperature methods,
will kill off the pathogens, which is a good start. Even if this
old soil is subjected to 170˚F for 30 minutes to try kill off any
pathogenic microbes, the existence of all the dead organic
matter in that soil would predispose it towards being an
incubator for these disease organisms. A complete cycle of
composting is likely the most practical method for reusing
old soil. Be wary of internet information advocating for
reusing potting mixes when pathogenic microbes, weed
seeds, and insects are not accounted for.
When using water from a reservoir, the temperature is
very important. Warm water over 76˚F promotes the growth
of harmful microbes. Where the water is recirculated, the
presence of organic matter (old roots for instance) is food for
these microbes. So, controlling the temperature and filtering
out organic matter to keep the water clean goes a long way
towards a healthier root system.
Allowing soils and grow medias to adequately dry in
between watering is very useful in maintaining an environment
where the pathogenic spores do not multiply so
rapidly. It’s not the simple presence of small colonies of
harmful microbes that kills plants. When massive colonies
exist due to optimum conditions for their growth, this overwhelming
force of harmful germs will bring an otherwise
healthy plant to its knees.
CONTROLLING PYTHIUM ONCE ESTABLISHED
The root disease must be identified early for most chemical
treatments to be effective. Sometimes particular pathogenic
diseases become resistant to certain chemical remedies,
and for this reason rotating between at least two chemicals
can be a better long-term treatment option. Use the QR code
at the bottom of the article to check out a link for specific
chemical options and associated concepts for controlling
Pythium and other root rot diseases.
Review some of the ideas in the detection section of this
article for getting a head start on identifying root disease.
To reasonably confirm root disease, you will need to pull
a plant or two up from the soil and examine the roots. You
can only truly confirm root rot through the examination of a
stunted and damaged root system.
“ Early Symptoms
will appear at the stem base,
and, if inspected, the roots.”
The presence of disease-producing microbes in the soil
or grow-media is difficult to completely prevent. As these
organisms can do so much damage to your crop, it is vital to
keep your greenhouse or growing areas clean. Grow media
that become at all anaerobic due to overly wet conditions
are highly likely to produce vast colonies of pathogenic
microbes, so proper irrigation cycles and grow media that
drains well is a must in this battle. In water-culture grows,
making certain that aeration of the water is always above
the minimum level is key. Temperature control is a major
factor in nearly every type of growing setup.
The best way to manage Pythium in your crop’s soil is to
prevent its introduction and proliferation.
Start clean and stay clean! Chemicals
are available to help control the disease
and work best when used early. Be aware
of the health and vigor or your crop; don’t
just water and move on. Keep an eye on
the health of your crop and check often
for signs of trouble.

choosing the right
lighting
BALLASTby Chris Bond
Selecting the right ballast
for your grow set-up
can be a daunting task
with many variables
to consider. But if you
follow Chris Bond’s
ballast breakdown, it
won’t be long until
you see the light.
There is a lot to learn and consider in the
world of plant lighting systems. Knowing the
differences between fluorescents, high intensity
discharge (HID), and light emitting diodes
(LED) will help you make an informed decision
and potentially save you time and money by
not selecting the wrong type for your growing
situation. One key aspect of this decision is
selecting ballasts for your lights. Not all ballasts
are created equal and they won’t all work with
all types of grow lights (although some bulbs can
work in different ballast types). Once you have
selected the type of grow light you are going to
use, it’s time to select the appropriate ballast.
54
Maximum Yield

Ballast Basics
Though any expert in grow lighting might cringe at the
comparison, ballasts for grow lights are akin to the sockets
you screw light bulbs into. They are a requirement for any
grow light to work. They operate on either a 120- or 240-volt
power connection (commercial applications can operate
at 22v, 347v, 400v, or 480v) and may be hardwired or, more
frequently, can plug in to any standard home outlet. Ballasts
are usually specific to the type of bulb being used, such
as high pressure sodium (HPS) or metal halide (MH), and
some are capable of switching between more than one type,
though there isn’t a ballast currently available that can
power all types of grow lights.
Ballasts help to jumpstart your bulb. When you turn your
lights on, the ballast sends a high-voltage surge to create
an arc between two electrodes. The ballast will regulate this
energy so that when the bulb is warming up, there is less
current. More current is available and steadily and reliably
delivered to the bulb when it’s ready to shine at full capacity.
Make sure to properly match the wattage of a ballast to the
wattage rating of the bulb type you intend to use to get the
longest useful life out of your bulbs.
To spread the light more evenly across your crops, a reflector
is often used. A ballast is generally connected into a compatible
reflector before the bulb is installed. Ballasts create a
certain amount of heat, depending on the type.
Magnetic Ballasts
Magnetic ballasts have been around for a while and are
the largest and least efficient of the three types. Magnetic
ballasts can be thought of as electromagnets inside of thick
metal or heavy plastic canisters or boxes. They generate the
needed energy by way of a large spool of wire surrounding
steel sheets. The current created is then sent to a single
induction coil. Capacitors then regulate and maintain the
voltage at the level needed by each light. These are the
types of ballasts often found in greenhouses that have been
in operation since the middle of the 20th century, especially
those using fluorescent grow lighting. They are usually the
cheapest of the three systems as well.
General Ballast Types
There are generally three broad categories of ballasts:
magnetic, digital, and electronic. These categories relate to
how the ballast keeps your type of light aglow. Don’t get too
caught up in the mechanics of it, but the basic differences
and explanations of the different types follow below.
Electronic Ballasts
Electronic ballasts, as the name implies, do not require a
magnet, but rely on semiconductors, microchips, and other
electronic components to regulate and supply the required
voltage and watts needed. They are usually considered
superior to magnetic ballasts for these reasons:
Weight — These ballasts, because of their inner circuitry,
weigh far less than their magnetic counterparts. They are
easier to install and place less stress on the physical structure
where they are mounted.
Efficient — Electronic ballasts produce less heat than
magnetic ballasts, which in turn results in longer useful lives
of bulbs. They also usually produce a better-quality light
spectrum than magnetic ballasts.
Operating Cost — Electronic ballasts are dimmable and
require fewer watts than a magnetic ballast to operate the
same bulb. Some electronic ballasts can run a wide range of
wattages because of their dimmability. It follows that fewer
bulb changes equals a lower operating cost.
“not all ballasts are created
equal and they won’t all
work with all types of
GROW LIGHTS.”

“a digital ballast can be thought
of as a smart electronic
ballast as it is governed by
MICROPROCESSORS.”
Digital Ballast
The digital ballast is often confused with the electronic
ballast. A digital ballast can be thought of as a smart
electronic ballast as it is governed by microprocessors.
Digital ballasts can perform the same functions as electronic
ballasts but are able to offer a higher level of precision as
to when and how much power to deliver. They also ensure
a more reliable and consistent operation and can log information
like temperature, lamp voltage, etc. Digital ballasts,
like electronic ballasts, are dimmable, but where electronic
ballasts are dimmable in 100- to 400-watt increments (though
they can be built to have more steps), digital ballasts can be
dimmed to land at any point between 400 and 1,000 watts to
achieve a more appropriate amount of illumination for the
crop being grown. These are often the most expensive type of
ballast. It should be noted that electronic and digital ballasts
are not interchangeable. Switching to one or the other type of
bulb will usually require an entire system upgrade.
Bulb-specific Ballasts
Now that we got the technical stuff out of the way, let’s look
at the ballasts used for different types of grow lights. If you
are using LEDs, then the lights are built into a board and the
following information is not relevant. If, however, you are
using any type of high intensity discharge (HID) bulb or fluorescents,
the differences outlined below may help inform your
decision about which type of ballast to look for.
Within the range of HID ballasts are those that accommodate
HPS, MH, and ceramic metal halides (CMH). Ballasts for
any of the HID lights can regulate current very precisely.
56
Maximum Yield

HID Ballasts
Ballasts for HID lighting are complex and dynamic. They
are built to perform a range of tasks specific to the smooth
operation of HID bulbs. They are also built to avoid overheating
while turning on and off thanks to the special circuitry
installed within HID ballasts. These facilitate the cooling of
xenon gas before getting the jolt of high voltage needed to
turn the light back on.
CMH Ballasts
Ceramic metal halide bulbs are a special type of MH bulb
and require a different type of ballast. These ballasts put
out very low frequencies and, therefore, are not often found
on electronic ballasts. This is not always the case, however.
Some higher end electronic ballasts can support
CMH lights because they have been installed
with microprocessors to avoid problems with the
interference. Most CMH ballasts, however, come
as a kit with the bulb and a reflector so the
problem of matching bulb to ballast is avoided.

ballasts are popular with
MANY GROWERS.”

and ballasts are popular with many growers due to their
longevity, reliability, and efficiency.
Double-ended Ballasts
Double-ended (DE) ballasts are a type of
ballast for HPS and/or MH bulbs. These
ballasts support bulbs that produce
highly luminous light as a result of the
combination of mercury gas and metal
halide. This combination produces up to
five times the light of a similarly sized

Ballasts for Fluorescent Bulbs
Ballasts for fluorescent lighting come in numerous types
as well to expand the array of available choices. There
are programmed ballasts, rapid start ballasts, and
instant start ballasts for fluorescent lighting. In all cases,
the ballast supplies the needed voltage to start and
regulate the current to ignite and keep the light output
steady. Without a fluorescent ballast, the useful life of
the bulb would be greatly reduced as it would draw too
much power and burn out.
Programmed Ballasts — These ballasts supply energy
to the bulbs once the electrodes or cathodes inside have
warmed enough to power the light. This gradual start
prolongs the life of not only the bulbs, but the entire
fixture. The programmed ballast follows a sequence
to start and operate the bulbs. With little variation, the
ballast will first initiate a preheating stage. After sufficient
current is present, the next step is to supply higher
voltage throughout the lamp to establish an arc that
produces the glow from the bulb that we are all familiar
with. Some high-end programmed ballasts can go from
step one to step two in well under one second. The main
advantage to the programmed start ballast is the ease in
which the bulb is activated — it will allow for many tens
of thousands of starts per bulb. The cost of this longevity
is that they take longer to light up and may flicker in
the process, meaning that your plants will not get the full
spectrum of light at the first flip of the switch.
Rapid Start Ballasts — These ballasts are not vastly
different, but as the name implies the lamp lights up
sooner than with programmed ballasts. In rapid start
ballasts, the electrodes are preheated in the starter, which
still reduces the voltage needed to start the light, but
it can essentially light up almost as soon as it
is turned on without risking the bulb’s
longevity. Bulbs in a rapid start
ballast will not last quite as
long as with programmed
start ballasts, but will last
longer than with instant
start ballasts.
Instant Start Ballasts —
These ballasts require
higher voltage than
either the programmed
or rapid start ballasts
but will allow for fluorescent
bulbs to light up
(you guessed it) instantly.
These types of ballasts can
be more efficient than other
types, but only in applications
where the bulbs are not frequently
turned off and on. Growers that only turn their
lights on once per day may do well with instant starts,
but if the photo periods are micromanaged with numerous
starts and stops, the instant start ballast will go through
bulbs much quicker than its counterparts.
“There are programmed
ballasts, rapid start ballasts,
and instant start ballasts for
FLUORESCENT
LIGHTING.”
If all of this still serves only to confuse you instead of
giving more clarity on the choices of ballasts out there,
don’t fret. Decide what you want to grow first. Determine
the characteristics of your grow space. Decide what
aspects appeal to you most. Is it initial start-up cost?
Prolonged energy savings? The quality of the light that
you want? Once you have these figured out, the choice
of ballast may fall into place more easily. Visit your local
garden, hydro, or grow store with the answers to the
above questions and they will most certainly be able
to help you select an appropriate ballast for your light
type, grow space, and crop.

The Importance of
growroom
hygiene
If you’re going to start growing
produce and flower indoors,
keep one thing in mind:
cleanliness is next to holiness.
Alan Ray details some of the
things to remember when keeping
your growroom clean. | by Alan Ray
Powerless against the whims of Mother
Nature, many home growers are bringing
their gardens indoors where they are
afforded easier access and more control
over the entire process. First-timers tend
to trend toward inside gardening as they
can experiment in private and learn as
they grow. Plus, there are no seasons.
Growing indoors definitely holds some
advantages over traditional outdoor
patches when it comes to weather and
varmints, but it also comes with its own set
of issues and enemies. Indoor plants can be
negatively impacted by spider mites, mold,
heat stress, and overwatering along with nutrient
deficiencies. That’s why growroom hygiene
is worth the elbow grease it requires
to make your growroom a showroom.
Or at least a room
that’s really clean.

Protect Your Investment
Monies expended upfront for your
growroom, coupled with your time,
talent, and effort, are investments
toward a payoff on the back end that
may well be worth their weight in gold.
Don’t risk having to watch everything
you have worked for, including your
dream, wither and die before your
eyes weeks down the road from
some unaddressed and preventable
misfortune. Lay as the foundation of
your garth — one of the first tenets of
indoor gardening — growroom hygiene.
Clean Leads to Green
It has been said “an ounce of
prevention is worth a pound of cure.”
In today’s vernacular that old saying
may translate to read “an ounce
of prevention is worth a pound of
cured.” Especially when preventive
measures have been taken from
jump street to protect your crop.
Grow clean, reap green.
A healthy growroom is pivotal to
a healthy harvest. Much has been
written and the standard already set
by successful indoor growers as to
what constitutes a clean growroom.
Absolute cleanliness. So, unless you
are operating out of a cleanroom
that formerly made semiconductors,
you’ll need to completely clean and
disinfect your growroom and all the
gear in it before introducing your
plants to their new home.
“
Never start
your new plants
in previously used
soil or plain dirt
from your yard.”
Making Your Green Room
a Clean Room
Growroom hygiene is of paramount
importance for good garden performance.
To begin your cleaning, pick
up and remove all dead or decaying
plant matter like leaves, sticks, and
stems that may have remained from a
previous grow. You want none of that
material anywhere near your growroom.
Burn it if safely possible. Next,
give the room a good sweeping to get
up any dirt or grow medium that may
have spilled. Afterward, take a vacuum
to the entire area. Sweeping gets up
the visible materials, while vacuuming
takes up the finer bits as well as dust
and tiny insects. Next comes disinfecting.
Essentially, you want to wipe down
everything in your growroom with a
good disinfectant, including the walls.
Natural Alternatives
There are many efficacious
disinfectants on the market but in
today’s more health-conscious society,
many growers are choosing to make
their own solution using natural
ingredients that sidestep the use
of harsh chemicals. Vinegar and/or
eucalyptus oil mixed with water is
a natural and excellent alternative
to chemical cleaners but there are
many others. Recipes are accessible
online. White vinegar is good and
kills salmonella and E-coli. With your
disinfectant of choice, thoroughly wipe
down all surface areas on which your
plants will be sitting. Disinfecting kills
off the harmful bacteria, mold, and other
microorganisms waiting to attack
your newbies. If using old containers
or pots (or even new) it is imperative
you wash them well with hot soapy
water before they come in contact
with your plants. And don’t introduce
those items into your growroom until
the room is clean and dry.
62

Clean and disinfect the floors by
mopping, if relevant. Make sure to wash
and disinfect all tools such as scissors,
clippers, tweezers, and any other instruments
you may have in the room before
using. Clean them afterwards to avoid
cross contamination. Isopropyl alcohol
will work nicely for that task.
The Dirt on Clean Soil
Never start your new plants in previously
used soil or plain dirt from your yard.
These mediums can contain many bad
actors such as parasites, microorganisms
and fungus, weed seeds, and a shovel-full
of other pathogens that can cost you time
and cause you unnecessary aggravation.
Always begin your grow with clean soil
that has been sterilized. There is some
debate whether sterilized soil is any
better than regular potting soil, so it’s
your call. Either one is superior to home
dirt. Just a few more growroom hygiene
tips and you should be good to grow.
• Don’t enter your growroom if you’ve
come in contact with outdoor plants.
Spores and microorganisms easily
attach to clothing. Change clothes
first. If you can’t change, throw your
clothes in the dryer on high heat for
10-15 minutes.
• Always wash your hands before
touching your plants. Germs and
bacteria can cause contamination.
• Keep all pets out of your growroom.
Their coats and paws harbor
numerous hitchhikers.
• Clean and disinfect your garden
tools after every use.
“
Vinegar and/or
eucalyptus oil
mixed with water is a
natural and excellent
alternative to
chemical cleaners.”
• Quickly remove all dead or
discolored leaves including
twigs, sticks, and any clippings
from inside your growroom.
Once things are up and running smoothly,
the hardest work is in the rearview mirror.
Your duties will be reduced to general
garden maintenance. Established plants
will pretty much grow themselves with the
proper amount of light, food, and water,
and the occasional snip or bend from you.
Follow these guidelines and you shouldn’t
have to worry about pathogens and mites
infesting your growroom and destroying all
your hard work.

FACTS ON
ENDOPLASMIC RETICULUM
by Philip McIntosh
Has there ever been a
cellular structure with
a cooler name than
“endoplasmic reticulum?”
ENDO MEANS “inside.”
“Plasmic” has to do with the
cytoplasm inside cells (it also
derives from “thin” or “flattened”).
A “reticulum” is a threadlike or veiny
network. All terms describe the
appearance of the endoplasmic
reticulum pretty well.
ENDOPLASMIC
RETICULUM is fun to say, but
not too many times in a row. So, it is
often abbreviated as simply “ER.”
THE ER is a membranous structure
found enveloping and stretching out
around the nucleus of eukaryotic cells.
This is a good place for it, given its role
in protein synthesis and processing.
THERE ARE two kinds of ER:
rough ER and smooth ER.
ROUGH ER is usually more
prevalent than the smooth kind. It is
called that because it looks “rough and
bumpy.” The bumps are ribosomes
(sites of protein synthesis) embedded
in the membrane.
SMOOTH ER consists of regions
where there are few, if any, ribosomes
in the membrane. Membrane vesicles
bud out from the smooth ER carrying
proteins to various places in the cell,
especially to the Golgi apparatus.
CELLS THAT are specialized for
secretion tend to have a lot of smooth ER
because the secretions are delivered in
vesicles that emanate from the ER.
PROTEINS DON’T work if they
are not folded into their correct shape.
A lot of the folding happens in the
ER with the help of proteins called
chaperonins which assist the amino acid
chains in getting into the correct
three-dimensional conformation.
ONLY CORRECTLY folded
proteins are allowed to be transported
out of the ER in vesicles. Too many
improperly folded proteins induce a
stress response that accelerates the
disposal of malformed proteins. Defects
in the stress response are implicated in
diabetes and neurological disorders in
people, and growth and developmental
abnormalities in plants.
ALTHOUGH THE ER is most
well-known for its role in protein
synthesis, smooth ER is also where
glucose-6-phosphate is converted
into glucose, a critical substrate for
energy production in cells.
