Hi I am building a grow closet in my apartment it is going to be small, but I am worried about smell. I have a ventalation fan venting outside, but was wondering if putting insulation in the walls would help with the smell. Or would this be a bad idea because it would keep the heat in the closet? I'm not sure and i'm new at this, any feed back would be great. Thanx. Steller
carbon filter... attached to a inline fan... Check out the diy section.. build your own... way cheaper... gonna have to come outa pocket for the fan.... insulation will not stop smell... and make sure you have negative pressure.. this stops smell leaks
