I also live in apt and my girls are NL too. Good thing that I did was to build a separate flowering chamber(In my bedroom) and my carbon air scrubber takes care of the odor.
I also let the digital timer to turn on the one of those.. Air Wick Scented Oil thing.. you know? and I placed a Hamilton beach True air right outside the bedroom. I am harvesting in 4 weeks and I don't smell shit!
I think this is what everyone is doing, right?
