what's your procedure while smoking?
I would say any precautions you would take good enough to cover smoking would cover the temporary smell of trimming.
growing/flowering plant(s) on the other hand, not so temporary.
I also use a phresh filter (4" x 20")
but
If I had to be 110% stealth, I would have failed.
both the wife and myself can/will catch "whiffs" of dank here and there
odd places like 20' along the wall, up through the floor, under the sinks of the master bathroom, drawn up by the negative pressure from the bathroom fans...
but then come down here, stick you face in the airflow out of my cabinet and you can't smell a damn thing.
I dry in my (dark) flowering cabinet after the grow to keep that stink in check
