GROWING TIPS
Sowing Your Seeds
The amounts in the table are estimates. A good rule of thumb is a density of 1/8” to 1/4” spacing in the tray. Consult the directions from your seed supplier. As you use your GardenChef®, keep track of germination and density of growing plants. If they seem a bit sparse, add a little more seed to your trays in the next growing cycle. Conversely, if they seem too thick, dial it back. There are numerous resources on the internet that can be helpful to develop your farmer instincts. In addition to planting tips, you can find
information on the pros and cons of various types of growing media.
Purchase Seeds from Reputable Suppliers
There are many suppliers online. Make sure they are reputable and follow safe practices for producing seed.
Growing in Potting Soil
The Growing Chart is a good starting point for growing in soil. We recommend beginners start with growing in soil as it is easier and plants take naturally to growing in soil! Use commercially produced potting soil. Do not use garden soil or dirt from outdoors.
Hydroponic Growing Media
The GC52 is not recommended for hydroponic growing.
About Nutrients
Potting Soil: Enough nutrients are present in potting soil for about 2-3 weeks, which is adequate for a single growing cycle.
Monitor Your Plants
The best way to learn is to check your plants daily and observe their growth and health. You can nip potential problems in the bud, learn how your plants grow and when to harvest for your particular needs.
Regular Cleaning
A healthy environment makes healthy plants. Clean your cabinet and growing supplies regularly to reduce the chance of contamination. See cleaning instructions on page 20-22 and sanitation guidelines on page 24.
Disease Prevention
In addition to regular cleaning, monitor your watering cycles, temperature and humidity levels. Overwatering, or too much humidity can cause mold to grow. Adjust them as needed.

CLEANING AND MAINTENANCE

CLEANING THE RESERVOIR

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 manually drain the cabinet; if this is the case, connect the drain fitting 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. Observe all municipal codes. Used water from the GardenChef is not potable. This procedure should take about an hour to complete.
2. Remove the bottom drawer(s)
3. From the HOME screen, press SETUP
4. In the SETUP screen, press SET RESERVOIR
5. On the MAIN RESERVOIR SCREEN, 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 floor! 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. When the draining is complete, press CANCEL to return to the home screen. Once the reservoir has been drained, wipe off any dirt with a clean rag. Clean the reservoir with a cleaning solution, i.e. hydrogen peroxide mixture. Follow the guidelines on the label of the agent. H2O2 concentration should be 5 tsp per one gallon of water. See note regarding cleaning agents on the next page (page 21).
7. Refill the reservoir with fresh water: on the HOME screen, press the SETUP button
8. On the SETUP screen, press the SET WATER button
9. On the SET WATERING screen, find the option for zone 5 and press the water droplet button on the right side
10. Allow the reservoir to fill completely. Turn off watering by pressing the same water droplet button for zone 5 on the right side
11. Press DONE to return to the HOME screen
12. Repeat steps 3 through 6 to drain the reservoir again to remove all residual cleaning solution.

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 filter and grow drawers every month.
GENERAL STAINLESS STEEL CLEANING
Clean the exterior of your cabinet when fingerprints 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 THEMSELVES. 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 GardenChef is not for drinking as biological residues may still be present and could be harmful.
Do not use steel wool pads to clean the cabinet as they will damage the steel and its rust-resistant finish. Do not use detergents or solutions that contain chlorides, ammonias, alkalis or abrasive cleaners. Use only environmentally safe, non-toxic 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

PERIODIC MAINTENANCE PROCEDURE AND TIPS

INSIDE THE RESERVOIR
A. DRAIN, CLEAN AND FLUSH RESERVOIR (Monthly)
SEE INSTRUCTIONS ON PAGE 20
INSIDE THE GROWING ZONES
B. CLEAN DRAWERS (Monthly)

1. Remove a drawer from the GardenChef
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 off the drawer with clean water
4. Dry with clean cloth
5. Replace in cabinet
6. Repeat steps for all drawers

C. CHECK AND CLEAN EJECTOR PUMP CAP (Monthly)

1. Remove the small white cap at the bottom of the ejector pump (the pump is the smaller blue cylinder attached to the larger filter canister).
2. Rinse the cap.
3. Place the cap back onto the pump

• If the water flow to your growing drawers is inadequate during a watering cycle, check the filter cap to see if it needs to be cleaned.

REPLACING THE LIGHTS

Occasionally you may need to replace a light bulb. It is a simple process, similar to changing the bulb on a fish tank hood. For part number, see the list on page 29.

NOTE: T5 growing lights running at the default time of 18 hours per day is considered high use and the efficiency of the bulbs will reduce approximately 10% after 20,000 hours. Bulbs should be replaced every 18-24 months to ensure best performance.

SANITATION AND FOOD SAFETY RECOMMENDATIONS

For your health and safety, please read the information below.
Microgreens are baby plants. They have intense concentrated flavor and more nutrients than full grown plants. They are not sprouts and are safer to grow than sprouts. Starting with Seeds
Make sure that all seeds you buy have been tested and grown as a food crop and are free from contamination. Do not use seeds from crops that have been fertilized with animal waste. Reputable seed suppliers test all lots of seed for contamination. Make sure that each seed package is labeled with the name of the seed producer or distributor, the lot number and the country of origin. Keep records of all seed lots in case of recall.
Sanitation
Use clean seed and growing media from reputable suppliers. Do not use garden soil or dirt from outside. Regularly clean and sanitize all growing drawers, cabinet and reservoir. Monitor the growing zones daily and clean at the first sign of mold or contamination. Adjust your watering cycles, humidity and temperature so that the fans operate regularly. Clean the cabinet between growing cycles.
Don’t let greens or seeds come into contact with contaminated surfaces, manure or other contaminated organic material.
Your growing space, hands and equipment must be kept clean at all times for handling microgreens. We recommend use of food handling gloves during plant- ing and harvesting. Use clean, potable water in the reservoir.
Clean Seed
You may choose to clean and sanitize your seed prior to growing. It is not necessary with microgreens and reputable suppliers test their seed for contamination. But, if you want to take extra precautions, use this method: 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 sure the solution has been removed. Plant as usual.
Growing Conditions
Microgreens are not sprouts and are not grown in the same manner. Commercial sprouts are generally grown in large tanks of water. If one seed is contaminated, it will contaminate all of the sprouts in the tank. Microgreens are not grown in this way. We recommend growing them in sterile soil or other sterile media which acts as a filter to remove contamination.
Harvesting
Microgreens are newly germinated, small plants and are usually harvested at the stage where the first true leaves appear. They 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. Make sure your harvesting space and containers are clean. Roots or clinging soil, should be removed and your micros should cleaned thoroughly before consumption.
Refrigerate cut microgreens. Treat them and any foods containing them as food. Note: basil is sensitive to the cold and should not be refrigerated. Use immediately or place in a clean container at room temperature and use within a day.

FREQUENTLY ASKED QUESTIONS & TROUBLESHOOTING

How much soil should I put in my trays?****

– You should fill 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 24 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., fill trays 2/3 to 3/4 full.

Why should the seeds be covered with soil at the beginning?****

– Most seeds like a little darkness while they emerge from their shells.
– For the best results, sprinkle them with a fine layer of sifted soil, just enough to cover the seeds.
– Usually 1 to 1-1/2 cups of sifted soil works.
– The sifted soil spreads easily and provides a nice blanket over the seeds for germination so that more seeds sprout and at the same rate.
– I ran out of mats and I need to plant now. Is there anything I can do? In a pinch, place a thick paper towel in the growing flat, and then add the potting soil.
– The paper towel will keep most dirt and debris from flowing into the reservoir, while allowing the tray to drain.
– Two paper towels fit nicely into a 10” x 20” garden flat.

When should I use nutrients?****

– If you are growing in potting soil, nutrients are not necessary for the first 2-3 weeks—usually the duration of a single growing cycle.
– The GC52 is not recommended for hydroponic growing as the media is sterile and there is no way to add nutrients.

Is the GardenChef pre-programmed?****

– Yes, the GardenChef is pre-programmed for many seeds with a default 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 maintenance be done?****

– The cabinet requires frequent monitoring and care. It should be inspected thoroughly and cleaned at least once a month.
– The filter needs to be changed regularly. Maintenance may vary with your degree of usage.
– Please refer to maintenance and cleaning procedures in this manual.
– Always clean the cabinet if it will be taken out of service.

Does the water reservoir keep itself filled?****

– Yes. Your GardenChef has been plumbed and hooked up to municipal water supply and it is pre-programmed to add water and top off as needed.
– You can also drain and fill the reservoir when needed. Follow instructions in this manual.

What do I do if the reservoir won’t fill or recycle?****

– Check to ensure that the connection on your city water and drain is open and free of blockage.
– Check for kinks in the tubing.
– The pump may need to be primed. See instructions in this manual for priming the pump.

What if there is no water flowing to a zone?****

– Make sure not more than two zones are being watered at a time.
– Only two zones 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 there is a weak/no water supply to the drawers during a watering cycle?****

– It’s likely that the screen over the filter is clogged with debris and needs to be cleaned or the filter needs to be replaced.
– See maintenance and cleaning instructions on page 19.

What if the drawers are not draining properly?****

– Check the drain holes at the back of the drawers and clear them if they are blocked.

MICROGREEN PROBLEMS

WHITE MOLD

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.
Note: take a close look. The root systems of some microgreens are fine filaments and resemble mold. Learn to recognize the difference.| ·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

SLOW GERMINATION

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  18-19, 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

When you’re spreading your seed out in trays, it can be difficult to get an even spread.  If you plant too densely, they will clump together, especially if they’re mucilaginous*.  When theysprout, 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 difficult.| ·  Decrease total seed volume planted in each tray
·  Spread seeds more evenly throughout the tray

The greens look weak and pale.  This is an all encompassing condition that could result from a number of factors.  It is difficult 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 propagation dome is removed at the  wrong time.| ·Make sure to read the seed growing instructions on the seed packaging
· Stick to a regular watering schedule
·Make sure you leave the propagation domes on for an adequate amount of time
·If growing hydroponically, check your nutrient concentration and TDS levels; make sure nutrients are mixed according to the manufacturer’s directions

*Mucilaginous seeds: seeds whose hull forms a gel sack consisting of proteins and polysaccharides when exposed to water. The purpose of this sack is to retain moisture around the seed during germination. It also assists the seed in holding onto the soil, so as not to be washed away while establishing a root to anchor the plant. Examples: brown mustard, arugula, basil, cress.
