"cooler" room with a 10000 btu a/c unit i mean the plants don't want it ice cold like we humans do ha ha

GrowinGreen23 Reviewed by GrowinGreen23 on . How big air-conditioner do I need? Does anybody know what size air-conditioner I need to cool a 10 x 10 x 7 room (700 cubic ft.) with 4 1000W lights? The rest of house is about 86 degrees to start with (at the time of night when lights are on, due to house walls radiating the heat theyâ??ve absorbed during the day). The lights are air-cooled, but still put off a good amount of heat anyway (a 750 cfm fan pulls air thru them, either fans getting old or the outside/intake air isn't cold enough). I was going to buy a 9000 BTU Rating: 5
