Putting together a CGE (sealed room

Hey all I need some senor advice on wtf to do as far as A/C types I can use for a CGE. I've got pretty much every other piece of the puzzle: Co2, Complete environment controller, 20 pint Dehumidifier, and 2 x 600 bulbs in a vertical stadium. I have 2 x 1ks on the side that I might use but as it is I'm not having any success running more than a 600 without having temps touch high 80's. I'm much more comfy keeping it around high 70's max 81 so I need an A/c unit . However all the portable units I look at exhaust room heat......

How do I remedy this issue? Even the dual hose systems mess up the sealed aspect of the room. I cant use KAC a/c so thats out of the question.

Also on another note, I'm running a 8 inch 700 cfm fan speed controlled through a reducer and 6 inch cool tubes hung vertically, and then exhausted. I've tried every possible setup and even tried the fan at full blast and reduced speed, and it doesn't make a significance of the coldness of the air I pull through it. When I am in the room the cool tubes are hot, like after about 30 seconds you want to take your hands off the glass. And there is alot of radiant heat around the glass. Like if I wear a black shirt and turn my back to the light I can feel the radiant heat, just as you'd feel on a hot sunny day if your under the sun and wearing black....ands thats with the 600........Room dimensions are 6W x 7L x 8H

ps: please no "you have to exhaust your room replies.......I've seen enough setups with 100% sealed on vented flowering rooms with amazing efficency and no ill effect.......so venting the room is out of the question......other than that, please chime in with intelligent solutions. Thanks :wink:

You can mod a dual hose portable A/C to be almost isolated.

You'll still be adding back CO2 regardless, so a minor loss should be managable.

The other option is called a "Mini Split A/C". They are pretty expensive, though.
