my controller would turn the fans on at 85 F and off at 78 F
The bubble counter would make an average of 2 bubbles every 3 seconds. I do believe co2 was working quite nice. When I stopped using it the plants did not drink as much. Actually a very big drop in how much they drank. With co2 my res would be about half empty in 3 days, when I stopped using it, my res was about 1/4 empty if that. I had quite a bit brewing. I will buy those 20$ co2 testers next time to see how much it really did produce. From posts I have read, people say to put new sugar in every couple days. From experience I learned my bubble counter did not even start working till about day 2 and would start producing about a bubble a second. It would mellow out to about 2 bubbles every 3 sec 4 or 5 days in and then in a week about a bubble every 3 sec. I would add sugar every week and change yeast every two weeks. From my observations of the bubble counter and how much solution was missing from the res I believe It worked nice. I did not even get a bad smell, except for once when I left my grow for 10 days. When I got home my house smelt like moonshine vinegar. When I get the tester I will post results. I will not use co2 the remainder of this grow. Trichomes are getting cloudy.
