Sup guys, my first post on rollitup, been reading for months and I love this place 
I'm about to buy a small grow tent (20x36x64) and put it in this closet.
However, i am concerned that I will not be giving the plant proper ventilation. I was thinking of getting a Panasonic Whisper (will this even work with a grow tent?) and exhausting the hot air above the grow tent, but as you can see from the picture, won't the hot air just stay trapped at the top of the closet?
Any suggestions you guys can give me for my grow space would appreciated. Mostly I am interested in a quiet inline fan that will give my grow tent proper ventilation. The closet in my office is the only place that I could grow without people raising all kinds of questions..
