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.

Also I have about 2 weeks left in flowering. Would the co2 even help now or should I just wait til text round?
