We do not have a greenhouse and no windows on the south side of the house. The shed is too dark and has electricity issues so that is not an option for my little seeds. I have the germinating seed all over my work area it does have lots of east and north facing windows.  Also it is a warm winter after some freezing weather in November and so I am putting some of the plants that have already germinated outside, but still in containers so that I can bring them in if it freezes again.
