Well I made the mistake of choosing a fairly strong smelling strain this go around. Im only growing 6 plants under 400w HPS, in my upstairs closet, but the whole house stunk by about the 5th week of veg. Vinegar worked soso.. but I recently tried the Glade's plugin "Air Neutralizer" scent. It works beautifully, no smell, barely even in my flowering closet. Just a tip..
