I start my 'inside' tomatoes late in the season, about a month ago, and just brought it inside tonight. It's about three feet tall or more and blossoming. I will have to pollinate it myself with a paint brush. I have a large 'shop' light over my long dresser for the light which I leave on at least 14 hours. I just started doing 'indoor' gardening last year but it's a lot of fun and I enjoy pampering my plants. I also have two dwarf lemon trees with fruit, an olive tree and an avocado tree inside in pots! [Pix below] I also have a greenhouse outside.
