If you don't/can't have sealed room, then supplemental co2 is pointless. Normal air quality already has approximately 300-500 ppm. Depending if you live in a city or not. The point of supplemental co2 is to get the ppm up there around 1500. You might as well sit your tanks outside your front door and let em open. It's not necessary to supplement co2, just a kick in the plants but to get growing.
