I have a room in the basement that stays warm due to the hydronic heating manifolds and I have started tomatoes and peppers before with a grow light, but if I was to start them now, which quite possibly could produce some good fruit, my room would be a jungle by May if the grow light remained sufficient with that much growth. LOL, its a common problem up here. BTW, have you noticed the size of jalapenos in the stores lately? Those things are not jalapenos--they are almost as big as Anaheims---and they have about as much heat as well. I think they are GMOs
