Question regarding ventilation.. I have read that the air needs to be completely exchanged at least every few minutes.
Ive got a grow area that is 0.8m3
Extractor fans that run at 90m3/h
So theoretically, if i keep the fans running 24/7 , it will do over 1 and a half change per minute, if im not mistaken..
Can i put my extractor fans on a timer, to only run every other minute? i.e. run for a minute, then rest for a minute and repeat.. This would mean approximately 3 air changes every 4 minutes..
