when I kill my lights?

[kpz352]

when I kill my lights should I kill my fan also??? Also how often and when can I add co2 I'm just adding it from a hose from an old paint ball gun and tank.???

They like air lights on and lights off. I would keep your exhaust and fans running all the same. I don't know about the CO2.

When you add CO2 to your grow space it ups the room temps, it is supposed increase the yeild by 25%.
Your air in and out should be on all the time.
