Hi all, thanks in advance. I am hoping to find out any thought you might have about this closed ventilation system. I want to create a stable environment with clean air. Would it be practical to run a sealed climate system running a carbon filter directly to an a/c unit? The idea is to keep a consistent level of CO2 [1000 to 1100 ppm], without any intake or exhaust from/to outside. This would hopefully eliminate wasted CO2 to the outdoors. Good days
