Hi I noticed your comment about high temps for your area. So y our sis the perfect brain to pick. I am having temps up to 89 with cooltube during lights on. 81 lights off. Keeping the res at low 70's in a top feed hydroton setup. Should I bother with the airconditioner during lights on? I can get the temps to 81if I use the air but it is very expensive. What are your thoughts on the situation?
