Will hanging this inside a closet grow by itself with 1 plant, with no ducting running out of the closet, be enough to address odour when flowering? I would hope fresh air would be pulled in through closet door gaps and the smelly air would be “scrubbed” by the fan/filter inside? Winter and freezing cold so temps aren’t an issue right now. Alternatively, I can have the fan/filter outside the closet in the room. Thanks!
