Venting C02 when the plants are sleeping?

    Hey Guys,

    I'm just about to do my first C02 grow. I have a nearly completely sealed room that has a carbon filtered exhaust system (with non-return valve so when fan is off it's quite sealed) on a timer.

    I'm running a Sentinel monitor and doser connected to a solenoid on a large C02 bottle. I have an unlimited supply of C02.

    I was wondering if it's good practice to vent the room when the lights and C02 are off? This means the room gets a change of air each day.

    As far as I know plants do not use CO2 at night, CO2 is used in the photosynthesis process. Maybe someone else can chime in with a better answer

    "Photosynthesis is the process by which plants, some bacteria and some protistansuse the energy from sunlight to produce glucose from carbon dioxide and water."

    No point if the only reason is to dump c02 j.
