I am wasteing a lot of Co2 when the exhaust kicks on. It comes on just around every 5-7 mins and is on for about 3-5 mins(out side temp verys) when the lights are on. The temp is set to 80-85. Exhaust coming on at 85 and off at 80. it takes about 5-7 mins for the room to heat back up 85 and then the exhaust turns on for 3-5 mins. The Co2 is on only when the exhaust is off. even so I use about 50lbs of Co2 every 10- 14 days. Im hoping that the ac will just make it able to have the exaust off longer. Maybe the exhaust will stayoff for at least 30min. I hope. Im working on the install now. picked me up an 18000 btu LG brand air conditioner from HD
Its a biggy, 130lbs. OH my back
