GROWING DO’S AND DON’T’S
DO MAINTAIN TEMPERATURE AND HUMIDITY
Keep the room temperature between 55°F and 90°F (13°C and 32°C), and the humidity level in the cabinet between
30 and 60%.
DO KEEP IT CLEAN
Keep your growing environment clean. Clean the reservoir, reservoir lter and growing shelves every month accord-
ing to the cleaning instructions on pages 17-19.
DON’T OVERWATER
Overwatering, especially at the beginning of the growing cycle can bring on mold and mildew. Most watering cycles
have been pre-set for every 4 days and are usually sucient for most plants, depending on the ambient temperature
and humidity.
DO USE HUMIDITY DOMES DURING GERMINATION
The humidity domes increase the temperature and humidity to enhance germination. Keep them on the trays for the
rst 2-3 days, with the vents closed. Remove them when the seeds start to sprout.
DO USE PROPER SOIL OR MEDIA
Purchase clean potting soil from a reputable supplier. Make sure there is a lter pad in the bottom of the tray to keep
soil from running into the water reservoir. We have had good results with Happy Frog brand potting soil, but there
are many choices on the market. Don’t use garden soil as it can get compacted and interfere with proper watering. If
growing hydroponically, purchase mats or other hydroponic media such as perlite. Note: depending on the media,
growing results may be dierent than soil. You may have to experiment with hydroponic media to determine which
type works best for growing dierent plants. There are many resources online describing the use, pros and cons of
the dierent types of media that are available. For discussion on hydroponic growing media, consult
www.epicgardening.com
DON’T OVERFEED
Overfeeding can cause damage to plants. For best results follow the instructions on your nutrient bottle. Most quick
growing micro greens (one to two weeks) do not require any nutrients. Greens with a longer growing cycle (herbs,
arugula, etc.) or greens that are used for multiple harvests require nutrients, and should only be added after week one
or two at the earliest.
DO KEEP pH LEVELS BETWEEN 5 AND 7
Balance your pH level at 5 in the beginning of the growing cycle for best results, as the pH is likely to increase as the
cycle goes on. The cabinet is equipped with an automatic dosing system to keep pH levels from going too high. Be
sure to check your dosing bottle regularly to make sure it doesn’t run out. Low pH is rare, but if it occurs citric acid
(organic) or potassium hydrochloride can be used to raise the level. Make sure they are mixed according to manufacturer’s direction and used sparingly. These and other hydroponic supplies can be purchased at a local hydroponic
growing store or on the internet.
DO SOW SEEDS A LITTLE ON THE HEAVY SIDE
Thin out young plants and allow others to grow and ll out.
DO USE HYDROGEN PEROXIDE
If you accidentally keep your humidity domes on too long or overwater your seeds, they may develop powdery mil-
dew. You can spray them with a mixture of hydrogen peroxide and water. Mix 1 tbsp. of hydrogen peroxide (17-35%
food grade) in 1 quart of water. Spray only the soil, as the solution can cause plants to rot in on themselves.
DO LOVE YOUR PLANTS!
Take time and care with your plants. Check them frequently for mold or other kinds of stress. You can see great
growth, even in one day!

CLEANING AND MANTENANCE
CLEANING THE RESERVOIR & IRRIGATION SYSTEM
1. Make sure cabinet is connected to city drain and water. If you are not hooked up to a drain and city water you will need to manual-
ly drain and ll the cabinet; if this is the case, connect the drain tting to a hose that runs to a drain or sink. Do not activate the DRAIN
function until you have a place to drain the water with a hose to a sink or drain, observing all municipal codes. Used water from the
cabinet is not potable.
2. Remove the bottom drawer(s)
3. From the HOME screen, press SETUP
4. In the SETUP screen, press SET RESERVOIR
5. Press DRAIN. The next screen that appears will ask if you are sure. Double check that the cabinet is hooked up to a drain. Otherwise it
will drain onto your oor! If you are not sure, press no and double check. If you are sure, press YES.
6. The cabinet will start to drain the reservoir. This may take up to 20 minutes. Once the reservoir has been drained, wipe o any dirt
with a clean rag.
7. Add your preferred cleaning solution (i.e. hydrogen peroxide mixture) into the reservoir. Follow the guidelines on the label of the
agent. The capacity of the GCV12 is 3.25 gallons. H
8. From the HOME screen, press SET RESERVOIR, then FILL. Filling should take approximately 20 minutes.
9. When the reservoir has relled, from the HOME screen press ZONE 1 and then WATER NOW so that the cleaning solution ows through
the cabinet’s piping system to ZONE 1
10. Repeat step 9 for ZONE 2
11. Once the zones and reservoir are cleaned, from the HOME screen, press SETUP, SET RESERVOIR, then RECYCLE. This will drain the reservoir of the cleaning solution and then rell it with fresh water for your next growing cycle.
concentration should be 5 tsp per one gallon of water.

CLEANING AND MANTENANCE (continued)
CLEANING THE GROWING DRAWERS Clean your grow drawers between each harvest. However, keep a close eye on the
environment and immediately clean any mold or organic matter.
Do not use any chemically damaging or toxic cleaning products such as bleach. Do not use stainless steel cleaner on the
interior of the cabinet. Using chemical cleaning products can be toxic and also damage the stainless steel drawers and
cabinet. You can use 30% hydrogen peroxide to clean the reservoir and water lines (5 teaspoons per gallon of water).
Read all warning labels on the hydrogen peroxide or other cleaning products.
Keep your growing environment clean.
Clean the reservoir, reservoir lter and grow drawers every month.
GENERAL STAINLESS STEEL
CLEANING
Clean the exterior of your cabinet when ngerprints
and large amounts of dust appear on the outer surfaces. Using stainless steel cleaner from your local
hardware store, spray on and wipe down with a cloth
going with the grain (As seen in the pictures). DO
NOT USE STAINLESS STEEL CLEANER IN THE
RESERVOIR OR IN THE DRAWERS. Stainless steel
cleaner is to only be used on the outer surfaces of
your cabinet!
CLEANING CAUTIONS
When you wipe down the reservoir, do not knock the pumps, misalign the pipes or the sensors.
Draining the reservoir sends water down and out from the drain hose. Water from the cabinet is not for drinking as biological residues may still be present and could be harmful.
Do not use steel wool pads to clean the reservoir as they will damage the steel and its rust-resistant nish.
Do not use detergents or solutions that contain chlorides, ammonias, alkalis or abrasive cleaners. Use only environmentally safe, nontoxic solutions in the manufacturers’ recommended concentration. Non-chlorine bleach from an environmentally-friendly company
may be used in accordance with the guidelines on the packaging.
DAMAGE TO STAINESS STEEL IS PERMANENT, COSTLY TO REPAIR, AND IS NOT COVERED BY THE WARRANTY
19
PERIODIC MAINTENANCE PROCEDURES
INSIDE THE RESERVOIR
A. DRAIN, CLEAN AND FLUSH RESERVOIR (Monthly)
SEE INSTRUCTIONS ON PAGE 17
B. CHANGE FILTER (30-45 days*—more often in areas with
hard water; lter is washable for extended use)
1. Locate the lter (large blue or white canister in the reser-
voir) and unscrew the canister counter clockwise. Make
sure to support very well the lter mounting bracket
while unscrewing lter in order to reduce the risk of
breaking mount.
2. Remove and discard excess water.
3. Change the lter and screw the canister back into place
by lining tabs up with head and cartridge. Push until it
bottoms out, then twist clockwise.
You may need to re-prime the pump after this process. See instructions on how to prime the pump on page 10.
* How often you change your lter is dependent on whether you
are growing in soil or hydroponic media. Once you get through a
few growing cycles, you will be able to determine how often it
should be changed. One indicator the lter needs to be changed
is inadequate water ow to the trays during a watering cycle.
Water Filter
Water circulation pump; white
filter cap at bottom
C. CHECK AND CLEAN FILTER CAP (Monthly)
1. Remove the small white cap at the bottom of the blue
cylindrical circulation pump.
2. Rinse the cap.
3. Place the cap back onto the pump
* If the water ow to your growing drawers is inadequate during a
watering cycle, check the lter cap to see if it needs to be cleaned.
INSIDE THE GROWING ZONES
A. CLEAN DRAWERS (Monthly)
1. Remove a drawer from the cabinet
2. Use a clean cloth with hot soapy water or hydrogen peroxide
solution to wipe down the grow drawer; make sure the drain
holes are cleared of any debris.
3. Rinse o the drawer with clean water
4. Dry with clean cloth
5. Replace in cabinet
6. Repeat steps for all drawers
20
REPLACING THE LIGHTS
Occasionally you may need to replace a light bulb. It is a simple process, similar to changing the bulb on an aquarium hood.
For part number, see the list on page 26.
NOTE: T5 growing lights running at the default
time of 18 hours per day is considered high use
and the eciency of the bulbs will reduce approximately 10% after 20,000 hours. Bulbs should be
replaced every 18-24 months to ensure best performance.
Remove the diuser shield by pushing it up with both
hands, then pushing it back far enough for the front to
drop down, and then pull out.
Grab each end of the bulb (metal ends of tube), rotate
clockwise until you can pull the bulb out.
Insert the ends of the new bulb into the black ends of the
ballast, then turn counter-clockwise until the bulb snaps
into place.
Replace the shield by lifting it up and back over the notch
in the back of the cabinet, push up the front until it clears
the front of the diuser frame, pull forward and drop into
place.
Push up and back over
notch in back of cabinet,
then let front drop down

SANITATION AND FOOD SAFETY GUIDELINES
For your health and safety, please read the information
below regarding sanitation, safe growing and food
safety.
Micro greens and herbs are not sprouts, but rather, baby
plants with intense avor and nutrients. There are dierences in growing and harvesting micro greens that make
them much safer than sprouts.
Starting with Seeds
Make sure that all seeds you buy have been handled as a
food crop, not a farm crop. Seeds that have been in contact with animals or animal waste could be contaminated
with salmonella or E.coli O157 H7 and could lead to food
poisoning. Reputable seed suppliers test all lots of seed
for contamination.
Make sure that each container of seed is labeled with the
name of the seed producer or distributor, the lot number
and the country of origin.
Keep records to ensure trace-back and recall procedures.
Sanitation
Always use clean seed, as stated above, and soil, tested for
E. coli and salmonella.
Sanitize equipment; regularly clean an sanitize all growing
drawers, cabinet and reservoir with hydrogen peroxide
rate recommended below. We recommend a thorough
cleaning/disinfecting weekly, or when new trays are planted.
Don’t let greens or seeds come into contact with manure
or other contaminated organic material.
Hands and equipment must be kept clean at all times for
handling micro greens. We recommend food handling
gloves during planting and harvesting.
Water in the reservoir should be clean, potable water, tested for bacterial contamination.
It is recommended that 2% chlorine from calcium hypochlorite be used as a seed sanitation method if your intention is sprouting. This is not necessary for micro greens,
but can be done as an extra precaution.
Using Calcium Hypochlorite
Rate: 3 ounces calcium hypochlorite in 1 gallon of warm
water. Mix thoroughly and soak seed for 20 minutes. Rinse
seed thoroughly in clean water, then nish soaking time, if
required, in clean water. Avoid breathing the fumes of
chlorine. Masks should be worn to lter the fumes is you
choose this method.
Using Hydrogen Peroxide:
Soak seeds in hydrogen peroxide. Add 5 ounces of 5% hydrogen peroxide and one ounce distilled vinegar to one
quart of room temperature water. Pour the solution over
the seed and let stand for 5 minutes, making sure that all
of the seed is in contact with the solution. Drain and rinse
the seeds in clean water several times to make ensure the
solution has been removed. Plant seed as usual. This
again is recommended for sprouting, but not necessary for
growing micro greens and herbs.
Growing Conditions
The environment in which E. coli and salmonella thrive is
warm and moist. Most commercial sprouts are grown in
large tanks of water, which tumble the seeds much like a
washing machine tumbles clothes. In these conditions, if
one seed is contaminated, it will be spread to all of the
sprouts in the water bath.
Micro greens are not grown in water. We recommend
growing them in sterile soil or other sterile media. While a
sprout bath spreads pathogens from one sprout to another, soil acts like a lter, actually removing the source of
contamination.
Harvesting
While a sprout is consumed whole, including the leaves,
roots and seed husk, micro greens are newly germinated,
small plants like you’d nd in any garden. All micro greens
should be harvested with clean hands, or using food handling gloves, clipped at least 2” away from the root system
and soil, using clean disinfected scissors. Ensure all debris
is removed from micro greens and cleaned thoroughly
before consumption.
Refrigerate cut micro greens, except basil (cut basil is delicate and does not like the cold). Treat them and any foods
containing them as you would any nutritious food.
If you love sprouts, consider growing micro greens. Their
bright and intense avor will be even more enjoyable now
that you have condence that they are also safe to enjoy.
22
FREQUENTLY ASKED QUESTIONS & TROUBLESHOOTING
How much soil should I put in my trays?
You should ll each tray 1/2 to 3/4 full with sterile potting soil. Make sure the soil is well moistened, but not overly
muddy or soupy. See Resources page 25 for some brands we have found to be high quality soils. For seeds with a
shorter life cycle like pea shoots, radishes, wheatgrass (1-2 weeks), 1/2 full is adequate. For seeds with longer life cycles
such as basil, oregano, arugula, etc., go with 3/4 full.
Can I mix in my seeds or cover with dirt?
For the best results for germination, sprinkle them with a ne layer of sifted soil, just enough to cover the seeds. Usually 1 to 1-1/2 cups of sifted soil works. The ner soil spreads easily and provides a nice blanket over the seeds for germination so that more seeds sprout and at the same rate.
When should I use plant nutrients?
The cabinet will display total dissolved solids (TDS) of the water in the reservoir. Note what the TDS is when you rst ll
the reservoir and try to maintain a TDS of 100-250 above that number. Add 2.75 oz. (80ml) of nutrients at a time, wait
15 minutes to adjust the TDS.
Is the cabinet pre-programmed?
Yes, the cabinet is pre-programmed for the seeds listed on page 15 for soil growing. There are a few empty positions
open in the menu for adding more seeds and you can erase and replace items in the seed menu. You can also designate your favorite seeds for frequently used cycles. All of the seed programs are adjustable for light and watering
schedules.
How often should I perform maintenance on my cabinet?
The cabinet requires frequent monitoring and care. It should be inspected thoroughly and cleaned at least once a
month. This may vary with your usage, depending on the number and types of plants, nutrients and TDS build-up and
growing medium (soil vs. hydroponic). Please refer to maintenance and cleaning procedures in this manual.
Does the water reservoir keep itself lled?
Yes. If your cabinet has been plumbed and hooked up to municipal water supply, then it is pre-programmed exchange
the water in the reservoir once a week and top o as needed.
What do I do if the reservoir won’t recycle?
Check to ensure that the connection on your city drain is open and free of blockage. If the cabinet is new, it may not be
primed. See instructions in this manual on page 10 for priming the pump.
What do I do if there is a zone that won’t water?
Make sure only one zone is being watered at a time. Only one zone can be watered at one time, so watering schedules
for each zone will be staggered an hour apart, if they are programmed to water at the same time. Check the programmed schedule to ensure it is not programmed to be OFF. If still no watering, access the reservoir and insure that
the pump is on and primed.
What if I see a weak/no water supply to the drawers during a watering cycle?
It’s likely that the screen over the lter is clogged with debris and needs to be cleaned or the lter needs to be replaced.
See maintenance and cleaning instructions on page 19.
What if the drawers don’t appear to be draining properly?
Check the drain holes at the back of the drawers and clear them if they are blocked. A pipe cleaner is ideal for this
maintenance.

MICRO GREEN PROBLEMS
WHITE MOLD
SLOW GERMINATION
Identication Remedy
White mold looks like a spider web crawling
across the surface of the growing media. It starts
out in one area in a small, wispy ball and then
expands quickly over the growing media.
Make sure your trays are CLEAN before
you plant
Decrease the humidity by increasing air
circulation
Decrease the seed density of your future
plantings, especially for mucilaginous
seeds
Try using some grapefruit seed extract
mixed with water as an organic solution
Identication Remedy
Most micro green seeds germinate in 2-4 days,
but some may take a bit longer. If you’re seeing
germination times that are longer than what is
outlined in the table on page 15, something is
wrong.
Increase moisture in the tray by misting
or running an unscheduled watering
cycle
Do a germination test on a paper towel
to see if the seed is bad. Place a paper
towel in a growing tray, moisten it by
misting with a mister and sprinkle the
seeds on top. Cover with a propagation
dome and see if they sprout.
CLUMPY MICROGREENS
FAILURE TO THRIVE
Identication Remedy
When you’re spreading your seed out in trays, it
can be dicult to get an even spread. If you
plant too densely, they will clump together, especially if their mucilaginous. When they sprout, a
few of the seedlings will push the rest of them up
into the air, suspending the roots and possibly
bringing dirt along with them. It makes harvesting dicult.
Decrease total seed volume planted in
each tray
Spread seeds more evenly throughout
the tray
Identication Remedy
The greens look weak and pale. This is an all
encompassing condition that could result from a
number of factors. It is dicult to troubleshoot
this condition if all of the other conditions above
have been addressed.
The weakness could be due to a lack of moisture
control—either too dry or too wet. In some cases
the seed is not properly planted, or the humidity
dome is removed at the wrong time.
Make sure to read the seed growing
instructions on the packets of seeds
Stick to a normal watering schedule
Make sure you leave the humidity domes
on for an adequate amount of time
If growing hydroponically, check your
nutrient concentration; make sure nutrients are mixed according to the manufacturers directions
