Question about sealed rooms???

Does anyone know if you need to exaust or fresh air intake in a sealed room when using co2???

I heard that if i run my my 630 cfm fan in to a carbon filter can66, in the same room, with out exausting it out side, I would not have to exaust fresh air in or out...

Thanks

If you're using CO2 you shouldn't need to exhaust/intake, that is correct.

Air exchange serves two purposes: 1) temperature control 2) fresh source of CO2.

As long as you have both of those taken care of, you're all set.

Yeah...as long as you can control the temps you shouldn't need intake/exhaust.

Add humidity control to that list.

i would look into a sentinel chhc-1 i know they are expensive but believe me they are absolutley worth it.
