Co2 Newbie

[amsterdamned123]

Hi,
I have a closed circuit ventilation system for the lights, and then a window unit and will be adding a CAN filter with a fan in the room. I was told you need to exhaust out the co2 sometimes, my question is how often do you have to exhaust the co2 out of the room and would the window unit be sufficient for doing this. Also would I have to have the window unit be on a timer or something when co2 is pumping?

thanks

I dont exhaust anything but heat. AC's have recirc options to keep the odor, temps and cold air in while only exhausting heat generated by the AC. Co2 is not needed at night, so get a photo sensor shut off or a timer.
