I was wondering if anyone else thought this might work...
Have a fan suck hot air out of a grow box into the bottom of a water resevoir and have an intake fan blow air from the top of the resevoir back into the box?
Will the water remove the odor and cool the air off enough to be sent back into the growbox?
Or something along those lines, maybe just have the air filtered through the water resevoir instead of back into the grow box... because im not shure if the air coming out of the grow box would have enough co2 when it was sent back into the box.
Any ideas???
