Hmm, I've never started hardening that early...I might have to try it with a few of mine though. It all depends on what size they are a month from now.
I use a fan in my grow tent to keep temperatures even and most of what's been stated above. I might be imagining it but I think it keeps the whiteflies and fungus gnats away too since the air is fairly turbulent near the top of the tent where the vent openings are.
