I have a 10x10x7 room with a carbon filter blowing air outside the grow room. Is it possible to not have smell and still run a co2 tank? My stupid self has been running my carbon filter and co2 at the same time thinking i had it right.

And if you're running air cooled hoods run them on their own intakes and exhaust.
