I have a 4x4 grow tent with a 1000watt light and right now I am only growing 1 master kush in a GH waterfarm. I have a 424cfm fan pulling heat from the bulb and pulling through a large 6" tallboy carbon filter. I cannot get the smell to go away. It is in my basement and I usually only smell it in my basement. But when my heat kicks on it blows it all around my house. I dont want to build anything around my furnace. I am getting a lot of suction in my tent, it is concaved on all sides even though I have another inline fan pulling in fresh air. Any ideas of what I could do to get this smell 100% gone? thanks.
