So if using co2 do you shut exhaust off. I mean the air movement is to bring in fresh co2???
CO2 is used in a sealed, climate-controlled space with HIGH light levels and elaborate temperature and humidity controls. Exhale bags are worthless as it simply can’t deliver sufficient CO2 to make a difference.
