You'll still need an ac.. an open window and a huge exhaust fan in the tent creating a passive intake will work in the winter((you gotta spit the stale tent air out of the room the tents in, like your attic or a conjoined room. . In the summer you're going to need a big muthafucken ac.. and those lights suck dude.. you need de fixtures if your trying to make money commercial growers all switched over to de. With those single ended coolable hoods you'll only get a lb each if you do good... .that's 4 lbs in 3 months using 4 inefficient lights.. you can pull the same thing using half the amount of lights... you can't be serious about this if you're not going to buy the right lights.
