So for example, a broccoli microgreen, some of which are germinating happily on my shelf as we speak - I heard that a microgreen of a vegetable contains all the nutrients of a full-grown veg? It sounds wonderful, but is it true? More on-topic, I grow microgreens in a sprouting tray with cotton shoelaces threaded all around and cut ends sticking down into the bottom of the tray which is filled with water, so they wick water to the greens. They grow so much better than when I had to remember to water them!
