This sounds like an awesome device! One quick question....When I do my closet grow next fall, can I have this set up to where the fan sucks the dirty air through the filter, and then exhausts the filtered air back into the closet? I just don't have way to vent to the outside for obvious reasons (heheheh). I can give good enough ventilation and CO2 and such, just no-where for the smelly air to go. I just worry that others in the complex will notice the smell, even with this scrubber... Think it'll get the job done?:bonghit::baggy:
