When running Co2 in a closed system with a ppm controller, will any problems occur if there is no air exhausted ever. For example if I were to set the Co2 controller to run at 1800ppm an hour after lights turn on (Is it necessary to wait??), and then just use the photosensor for night turn co2 off. Will the Co2 naturally come down in ppms before the light turns on so I wont lock up the stomatas? AC will be used to handle heat of the air cooled 1000 horilux. Should I use Co2 all the way to the end of Flower? Peace
