There will be a limit where the CO2 is depleted and the plants will be smothered with O2. In certain situations, the extractor will need to maintain a negative pressure on the enclosure for scents.

can't i'm afraid ..how fast does it rise i gathered you know? ..high light is a relative term, can you be more specific? How fast does it rise?, in what temps? does rh% have something to do with it one way or another?
My tents aren't totally shut when bloom lights are on
I usually have the tent door flapping open abit and having the circ fan on alll the time there is some "passive" ventilation. So my tent isn't totally sealed.
It's something to think abut for sure

It comes back up instantly with air circulation. My room will go from 1400ppm to under ambient in well under 90 minutes if the co2 is off.
Co2 is something you want to remain static with the lights on. If the levels fluctuate, the plants usually adapt to the lowest level quickly.
CO2 is carbon dioxide, the stuff animals exhale.
In a space that isn't ventilated, plants will use up the available store and then stop growing because it's a necessary basic nutrient. If you're in with the plants or if there's decent fresh air circulation, they'll get plenty.
The other option is active supplementation. Don't bother with CO2 grow bags; they don't produce enough.

People get all caught up in NPK but plants are over 95% carbon, oxygen, and hydrogen by mass.
