I have 2 600s running on 9 2 week old plants, they are currently turned down to 400 each. Its about time to turn them up but when i do it gets a lil too hot. its at about 75 when they both run at 400 and 83 turned up all the way. They are cooled by two 400 cfm 6 inch fans that come to a joint and run straight through both lights. should i get another fan to suck air through from the end of my ducting or should i just invest in an ac unit?
thanks
thanks
