To what an extent can I avoid replacing the air in the grow area when the lights are off? My small dehumidifier cannot keep up when I am venting aggressively. It seems I have to balance older dry air with new moist air. Which is worse?

When the lights are on, the temperature is much higher so the humidity is ok even with venting.
