Cooling a sealed room?

Im setting up this 10x12 room... gonna have about 4 or 5 600's plus a 400 for moms and babys. The room will be sealed, with CO2. My question is about cooling... Is it best to run all lights in parallel with a strong fan, with the intake and output connecting to vents through the wall, so as not to deplete CO2, or is there a type of stand alone AC unit that does not need a window vent? Seems much easier to just have the ac on, and not cut up the wall.

Thanks in advance, ++++rep....

Haha I have an apartment and have 4 6" holes strait through to the closet it's the only way to go, get an ac that has intake and exaust vents. Most ACs pull air from the room and expell it outside... If your running co2 these suck. Hydrofarm sells one but you can get it cheaper on google shopping. Only other way to go would be one of those window hung ACs that sit outside your window

AC units do not exchange room air - the heat expelled comes off a condensor unit heated via freon. You can get a portible unit at any Lowes / HD. The drawback is the power they burn.

Instead, consider light movers or vented hoods. In the end, if you are putting out that much heat it might be best just to forget CO2.

I like that idea - I think vented hoods are the way to go!

Uhh, actually if you're running higher temps you really WANT the CO2. It allows you to run much higher temps than usual. Unless you mean just scrap the CO2 to vent the room even more.

And yeah Rick is pretty much right about the portable A/C unit. It's just the condenser's heat that gets exhausted. This is what I have and it works pretty well. If you're considering this option I would suggest you chose a model that has a 24 hr timer and auto-restart in case of power outages. This is the hard to find stuff. You can find all kinds of these things at Lowes or HD during the spring and summer months. But most all of em do not have the 24 hr timer or auto-restart, so do your research. I think Haier makes a model that does...

And I don't know where you're located, but if it's in a hot ass place like me then you better have that a/c unit, cause I have a 6" vented cooltube and I could never run without the a/c unit in any season other than winter. Good thing is, stick to a lower wattage/amperage unit and it won't raise the bill that much for the ton of benefit that it gives ya. I rely heavily on mine, and I think it raised the bill about $25 a month with a 400 watter that it has to cool down.
