Which trays are best for growing microgreens at home?
The best trays for you will depend on how many people you are feeding and how frequently you want to eat microgreens. For a family of 2 using 1010 trays will let you plant a greater variety of greens while saving space. For larger families with kids growing a few 1020 trays per week of favorites like pea shoots and broccoli microgreens is a great start for adding more vegetables to your diet.
Always choose a heavy-duty reusable tray made from food-safe plastic for ease of cleaning and peace of mind.
How many trays do I need?
You will need enough trays to have one set growing and another germinating at a time. Ideally having one extra set as well for those weeks that you want to grow more. If you plan to eat three trays worth per week a 10 pack would be just right for you.
If you will be growing for market it is best to have at least 4 sets of trays; one germinating, one growing, one ready to harvest, and one waiting to be cleaned.
Do I need both trays with holes and trays without holes?
Yes, when growing microgreens you will need to have trays with holes to grow in and trays with no holes for bottom watering and stacking. The only time this does not apply is if you will be growing in a flood and drain system like our Automated Grow Rack.
How do I clean my microgreen trays?
If you are using our heavy-duty, reusable trays:
You will start by removing all of the growing media and roots left over from harvest. These can be fed to livestock or added to your compost.
Spray the trays off using a hose on a higher pressure setting.
Wash the mostly clean trays in hot soapy water or run them through your dishwasher. (Just remember to turn off the heated dry function)
Rinse your trays with clean water and allow to air dry.
For added sterilization, you can use H2O2 or a mild bleach solution.
Should I use shallow trays or deep trays?
For most microgreens, our shallow 1 ¼ inch trays are perfect for saving on growing media and making your plants easy to harvest.
For tall-growing crops like pea shoots, sunflowers, and wheatgrass our deep 2.5 inch trays give your crops a little more support and space for longer growing times.
