I hear ya Tran. We even discussed earlier that your sealed room gets no CO2 for the end of flowering. Not even some fresh air, which has 3-400PPM of CO2. Amazing, but feasible I guess as plants certainly don't look like they're doing much thru the leafs at that point.
But in veg...it's all about high energy and growth. I don't understand how a room full of healthy vegging plants wouldn't deplete all the CO2 in that space.
