I shut my bud room tight during their dark period. I have not seen any problems from it.
spongebobsmokepants Reviewed by spongebobsmokepants on . getting stealthier.. i've switched my lights to 12/12 they go off at 9 am and back on at 9pm. but my exhaust fan is really loud my question is... can i put my exhaust on a timer as well so that during the day( or nightime if your the plant), the exhaust is off but the intakes stay on? will this slow or speed up flowering? could it decrease yeilds?
