OK so from what i understand, if i have a window ac unit and a standalone dehumidifier...then all i really need is a co2 controller?
My guess is that like you said the ac will probably be running constantly during the warm summer months light cycle? so a timer will suffice? my ac unit does not have a thermostat, just high med and low settings.
and the stand alone dehumidifier will run seperately also.
So adding just a co2 controller will keep my rooms co2 level right?
Does a window ac unit recirculate the air inside the room or will it suck out the co2?
AC's do recirculate the air in the room - so CO2 loss is not an issue. Most AC's have a vent that can be opened to allow a small amount of external air exchange. If no vent lever is included, most of these types of AC's will have a small hole to allow for external AC air exchange - and this can be a source of CO2 leaks - though most rooms will loose this amount of CO2 through the cracks in the walls and floor. If concerned, this hole can usually be plugged with a rubber stopper or tape.
