You're gonna need some odor control other than the fart fan in your bathroom.I'm using a bathroom fan for a vent.. yes boys and girls a bathroom fan. I am on the third floor of a building and no one is that close will this eliminate most of my smell? and I don't have a carbon filter, yes I said don't....
if your only option is your vent in your bathroom then maybe you could unscrew the fan, and place a carbon filter in there, and then screw it back, or you could try putting something strong smellingn right in front of the fan, but marijuana overpowers anything if you dont have the proper filter in my opinion.
hope i helped
