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?
If it's cold where you are,then it would decrese and lengthen flowering time. It would also depend on whether or not the temps will decrease 10 or 20 degrees.Is the fan you are gonna run,gonna draw outside air or inside air? My fan is plugged into a fan control with a temp gauge.Comes on at a certain temp and off for the same.Depends on how you set it or locate it in the room.
