buddy of mine has some og kush growing and the air coming from the carbon filter still stinks and the plants are STILL IN VEG! Of course the room that the tent is in stinks which is not as large of a problem as the air outside of the house smelling. He has a brand new 425 cfm growbright carbon filter (filter connected directly to fan to fan to ducting to reflector to ducting and out). Would upgrading to a much nicer fliter such as a mountain air fliter do the trick or would it be better to buy a ozone generator and place it inside the tent? Any help would be much appreciated. thanks guys!
