We've got odor killing gels in the grow room itself with a bucket fan blowing more odor control on the exhaust side of the room to kill off any odor that may get past the odor control in the room. Worked great for the entire grow and we had company over plenty of times without one person smelling a thing. That with the a/c running on hot days. Kill the odor as close to the source as possible and you will be fine.
