Hey, hunter, even though you are in a greenhouse, I'd hold off on this for a few more weeks. Beginning of March and maybe you can get away with it. I would say beginning of April might be more realistic. I started some plants, as well as some tomatoes, eggplant, and a bunch of flowers in a greenhouse in mid April last year. Sadly, they all froze one night, and never recovered. Lost two tomato plants, all the eggplant, most of the flowers. My poor little pot plants... nixed. :/
I'd say let it warm up a little bit still. Just my two cents. Happy growing to you!
