How to control air renewal indoors, how often should I turn off and on the extractors and heaters in the grow, can I leave them off at night while the light is off??
yeah you can have the extractor off at night i did that for years , but humidity rise significantly in the tent at night so now i leave the extractor running 24/24 wich help with humidity at night
Cannabis is a air or wind plant so to say. Might be able to in vegging but not flowering. Plus your humidity you need to be aware of. Keep that in check. Mold, mildew, and rot are no fun at all.
