We started planting our micro greens on December 12, 2016. We planted them by spreading seeds on two inch dirt, then spritzed them lightly with water, so the water wouldn’t disturb the seeds, and then added a cover. On December 14 Kate covered my lettuce in vermiculite, to keep the seeds warm and trap moisture for the seeds, and put it on a hot pad. When we got back to school after the winter break, and a cold front on January 6, some of the micro greens were good and ready, such as the arugula, the cucumbers and some of the different lettuce mixes. Others, however, such as the basil, had rotted and had to be disposed of. Then still some other lettuce mixes, and parsley still had not grown fully. We tried a variation of techniques like adding vermiculite to some, putting some on heating pads, and even putting some in with other plants. The ones that did the best were the ones that were put on the heating pads.
My red sails lettuce mix was still not growing (besides a few sprouts), even though it was put on the heating pad, and was one of the more pampered. It was said to grow in 7-10 days, so, that discouraged me some. I believe it was because it was one of the older seed packets we had. Some things you can do that make your micro greens more likely to grow are, as we learned, putting them on heating pads to keep them warm (if you’re growing them when it’s not so warm outside), keeping them in a controlled environment, such as a green house, giving them good air flow, planting them in the spring (so they get more sunlight), and planting newer seeds. Some things I would like to experiment with given the chance to grow them again would be, putting a clear cover on them, growing them in a warmer environment, or even putting them under warming lights.
