Newbie vent question

Been searching forums but don't quite get the answer i need.

In a grow room setup, Is the intake/exhaust fans on 24/7 in light cycle, or can I cycle them on and off corresponding with temp/humidity levels.

ty for any advice

No you can cycle them, you really only need it to get rid of heat buildup and sometimes humidity

I run mine with a carbon filter 24/7 to combat the smell.
