I have a small grow cab, 1/2 bathroom actually. Heat has always been a problem reaching 116 degrees at times. I know this is to hot. My quandry is: Do I buy a swamp cooler, (added humidity to deal with), or an air conditioner/heater unit? Grow area is 4ftx5ftx7 ft or about 140 cubic feet. All you experienced growers should be able to give me a good idea of whast I need to do, please do! Hiigel
