my grow room gets pretty hot about 85-90. Im thinking about getting a portable ac and use co2. My issue is that i have a carbon filter running at all times. Is it possible for me to run the ac and co2 when lights are on, and keep carbon filter off, (12/12) than when lights out, ac is off and co2 is off and carbon filter back on? or do i need to remove stale air at all times?......right no wmy lights are being cooled from another room through the lights and out to the attic.. carbon filter is exhausting out the attic also....helppppp anyoneeeeee
