If I have a tent in my closet and exhaust a 600w mh hps into my bedroom will it get to hot? I can't cut holes in the wall. What if I left the bedroom window open?
The exhausted air from your closet will be warm but I dont think it will be enough to heat a room though. Imo, having extra ducting helps lower the temp of the exhausted air and sure beats cutting holes in walls...sometimes...sometimes putting holes in walls can be fun
