damn, u must have had a serious grow going on...
i'm pulling my through, completely sealed off so it's presurrized, and no grow room air gets in, and then i have the dryer ducting that is connected to an a/c vent 30+ ft away dropping in cold air...
this weekend i am going to go and get a carbon scrubber w/ fan, and cut another hole in the ceiling and let that pull smelly/stale air out..
the way i got it now, has got my temps at whatever i have my house a/c set at..
never thought about blowing it through....
