I'm getting temps around 90-92 F, I have an older 1000w HPS with new bulb and new 1000W MH. The area is 5 1/2 ft. x 12 feet and 9ft high. I installed an exhaust fan that said it would pull out 120 CFM. I have to run it at all times?? WHY?? I made a fresh air vent and you can hold a lighter 6 inches away and it still gets blown out?? I need some relief? Does anyone have any ideas??
