i need AC for my CGE

hey guys, just built a CGE and have clones goin right now, but i know once i flip a couple thouies on the temps are gonna get way too hot...right now it sits at 70-75 with just a LED for the clones.
i dont want to exchange any air with the outside, so what are my options?
thanks!

You can get an AC that will recirc the air in the room. But you will always need fresh air, to get rid of humidity, and oxygen. Either way you have to pull fresh air in and blow air outside. Weather it happens through doors windows or vents.
