Running the fan during lights off? - Growroom Lighting - International Cannagraphic Magazine Forums

I'm wondering how nessasary it is to run my main vent fan during lights off. I'm trying to optimize stealth and run during night time when I am home. I'm wondering how nessasary it is to run the fan when the light is out.

One option i was thinking of is running it for 15 minutes every hour or 2 hours just to pull some new air in. Any ideas?

If there is no fan running the cab does not have a negative pressure and i would think you would risk the smell leaking out through your intake.

I leave my intake and oscillating fan on during lights out because they cannot be heard unless you get right next to the cab. I run my lights from 11:30pm-11:30am usually no one is over at this time besides my 2 bros who know bout my grow. With my exhaust fans on it is just too loud for lights out period anyone would hear it who came over. I think enough air is circulated with just my intake on for lights out period.
