I got the co2 burner hooked up today. The controller that it came with didn’t give a reading of the current level of co2. It bothered me because if the damn unit is burning gas, I want to know why. I luckily had one at my house and ran home to get it. It was a gorgeous day today in the high Rockies and it was warm in the greenhouse. The exhaust was consistently running and it was 85 inside. The co2 level was around 500ppm. I turned on the burner and took a few minutes to smoke a bowl. I was intently watching the digital display. After 15 minutes I shut the burner off. It did not change the levels even in the slightest and I’m not wasting resources. I’ll be holding off on co2 in the greenhouse except for cloudy days or when it’s far colder outside… More To learn… In over 30 years growing cannabis this is the first time I’ve ever tried to use co2 in a greenhouse.
