Okay, silly question here. We have a new 8x10 greenhouse and want to grow veg and flowers from seed. However, it is unheated (no electricity) and it seems like it's too cold for the seeds to germinate out there and we won't have enough window sills in the house for everything we want to plant. We don't want to miss the planting season waiting for it to warm up. What do people do? Should we just wait and get plug plants or stick with things that like to be planted in the cold, like beets and some lettuces?
