I was really puzzled as to why.Last night, as I was checking the sponges for any sign of life, I realized what was wrong.Lettuce is a cool weather crop. I had made an attractive AG display in a corner, so there are several Aerogardens in close proximity. It was hot! Way too hot for lettuce to germinate.So I started a new batch of romaine across the room where it is much cooler. I'm betting this one will be the usual success!
