3500btu's of a/c per 1000watts of light will sort you out, and get some water chillers, the chillers will protect your investment, personally i would leave the room at 90 and run co2, the plant love 90F with co2 and just use the water chillers, i found a guy on ebay with polar bear chillers for 400$ 1/3 HP will cool 100gallons of water atleast 25degrees
