It's a canister filled with carbon filters.Odor is a particle.It can be caught in a manner than it would be displaced or removed odorless! Much like what charcol does for moisture.It removes it from the grow room and traps it.I'll tell ya a simple way to remove moisture.Build a small can out of sheet metal or use a five gallon bucket.Fill it with KINGSFORD charcol,to the top! Cut a 4 inch hole in the bottom before ya fill it.Cut the same in the top.Attach 4 inch dryer flex to it on both end put a fan drawing not blowing,and vent to underneath the house.Change the charcol twice a month.Moisture will make charcol mold and mildew.No worrys bout mold if ya change it.

GaGrown Reviewed by GaGrown on . Odor Question Hey, I'm new to growing and am growing two plants in an enclosed area. They are very young (5 days), I am wondering how strong they will be when they are flowering and what to expect? What precautions do I need to take? Any info would be greatly appreciated! Thanks....
