my good neighbor who always gives me tomato plants has it set up in his basement. a grow light layering shelves. whatever he does, year after year it works. I can see the grow light coming out of his basement window at night. Right now, I am guessing he has begun the process. I will again add, I don't really do a veggie garden. these plants go in big pots that are positioned in what little sun my property has as we have tall trees. And to add, with lots of Amish around and the two of us we are good with veggies.
