Is it possible to make a activated charcoal filter without it being a filter? My grow room set up is in a closet space with about 4' x 5' in space with keeping in mind just a mother plant. And once I go to flower that plant I want to be able to not have an odor problem. I would assume one plant wouldn't cause much damage but I just want to cover my p's and q's. Is there a way you can put some activated charcoal in a sock and suspend it over a fan on high speed to help absorb the odors? Or would you have to go with some kind of filtration set up with your grow lamps? Thank you for your help!
