It's not gonna do much.

And why are you turning off the fans at lights out? That's not a good idea.

It’s more of an air circulation thing, it’s best to keep air circulation going 24/7 to avoid sharp jumps in Rh% as well as avoiding mold/mildew issues. It also helps strengthen stalks as the breeze gently brushes them.

Unless you have a sealed room, adding CO2 is largely useless, as your exhaust fan will just blow it away.
