It seems as if this is a quick and easy to grow micro greens indoors with very little effort. The biggest problem may be to be able to get bulk seeds over the winter. Single packs of seeds would not seem to make much economical sense unless you can get them at half price at the end of the season. May just have to make another buying trip to Home Hardware and get all that they have.
Later in the week I may just get rid of the other crops that have not done well and try something else.
