I just harvested my first crop of microgreens – successfully — last week. While it is supposed to be really easy to grow, I tried to grow them 3 years ago but it was a complete failure. I bought the trays, poured potting soil, and sprinkled microgreen seeds on top and left them in the greenhouse. The growth was spotty, and when I went to harvest them, they were tangled in clumps of soil that made them inedible.
Wanting to have microgreens for my salads and sandwiches because of their incredible nutrients, I did some research and started growing them again. This time, I used coconut coir, or coconut husk, instead of soil. I also poured lots of seeds on the coir and I watered them every day. It’s amazing what happens when you pay attention to your garden! In just a few days, I saw sprouts that grew into a lush thick blanket of microgreens.
My new plan is to grow less but start new batches every 2-3 weeks so I could have a steady flow of microgreens. To help me remember to water them, I placed them next to the fish in my aquaponics system so I feed the fish and water the microgreens at the same time.
