    Default co2 and air conditioning

    Not to sure if it should be in here, advanced growing or another section, possible a co2 section??
    This video

    I was thinking about designing a lung room, for a micro grow when it reminded me of co2 diffusion in a fish tank, and that co2 can be absorbed into water quite easily. With reference to science and the video this will increase acidity to water, so no taking the water from the A/C and returning it back to your grow medium. But how does this relate to co2 depletion from a closed grow room?
    My idea was a square tube that took air through a scrubber, past a A/C unit and then had the co2 injection port back into the grow room. But thinking logically, without knowing how much co2 (without data) would be absorbed by the A/C unit, to add to the amount of co2 per sq/ft per hour and not utilising a co2 meter, but math.

    Sorry it's been a little while guys,

    I'm not sure why an AC unit would absorb CO2, surely they are sealed?

    Because co2 is in the air, and at high humidity levels the A/C would take out some of that humidity in water form also taking out the co2. The way i looked at it was that co2 was in the air that the chap breathed out resulting in it being diffused within the water?

    Would be great if someone who runs AC in a co2 rich environment could PH check their water ^^

    Ok so did the test as in the video above, the PH of the water to start with was 6.1, after a few long blows of exhaled air into the water the PH lowered to 5.6. I then left over night and retested this in the morning, where the PH went back to 6.1. My own conclusion is that if growing in a small space and you think it's a good idea to run the condensed water back into your grow medium then don't. I can not test how much co2 would be absorbed from an A/C unit as i can't currently measure PPM, but my guess is that a A/C unit would absorb co2 from the sealed room. TBC
