Well I can't say for sure because I'm still on my first grow over here (lol) But I do research a lot before I even start, just to make sure I don't get it wrong.
What I will say, is that I insulated my grow box, actually built my box out of insulating, and my temps with my lights on sit at 30C or just below in my veg box. My flower box sits at roughly 25-29C. If I didn't have my exhaust fans blowing air out it would be even hotter still!
So yes it can work, quite well even. As long as you don't waste the heat you already have from the bulbs then your good.
But I do strongly believe that if the temps are too low - even if they don't die - they will stunt and not grow to their full potential.
Either way dude... good luck and keep me updated
