Colombo CO₂ SolenoidPlants only absorb CO when your lights are on, so there is no point in adding gas at night time. Not only is it wasteful, but carbon dioxide binds to oxygen and you can cause major distress or death in your livestock. The Colombo CO Solenoid should be used with a domestic timer (just like your lights timer) and automates when your CO comes on and off. I recommend it comes on 1 hour before your lights come on and turn off 1 hour before they go off
