Great radio show. I have a question that Tom brought up in the last show. He talked about turning his pH probe into a co2 meter by using a semipermeable membrane with 4dkh solution that was permeable to co2 and not water. Could you put a kordon breather bag and fill it up with 4dkh solution and put your pH probe in there then have an instant co2 meter?
