Ive had an A/C running basically since beginning of June in my living room where the tent is located. I have a 4in
vivosun exhaust fan. My temps during the day get to about 77F and at night gets down into the 60’s. The A/C helps greatly.
As for a chiller, no I am not running a chiller. During lights on which for me is 12pm-12am I throw ice bottles into the res system which keeps the temps of the water under 73F at all times. It’s a bit annoying since I have to lift the lid up to change the bottles every few hours, but I do not have the room for a chiller so it’s what I have to do.
eventually a chiller will be next and also I’ll change to a RDWC system for the less hassle of nute changing
