In my experience you should go for a strong Sativa-Indica hybrid like White widow. Will take a bit of heat and still finishes up in a reasonable time.
I grew WW from Nirvana in a wardrope that was running consistantly at around 35%c lights on and it didn't show any stress at all. Perpeptually for about 8months, Yeilded shitloads.
Also white widow is pretty much idiot proof, a good strain for beginners if thats what you are.
