aircon give of masses of heat,
the thing to do is to have sealed unit cool tube or other air cooled hood for lights, this is in a cirdiut that collects air from outside sucks it hthrew the pipes over the lamp and back out side,, this gives cooled lights without smell escapoing or humidity!, then the aicon blows in cool "dry air to cool the roon, oscilating fans then circulate the air within the room, additional heat extracor and filter fitted without light is turned off during the period of co2 injection and starts when the thermostat needs to run it!, this way oyu maintain a cool co2 rich enviroment!
