Try one morning without the bag and I bet you'll be at 800 to 1000ppm's. I'm not using co2 but when the house is closed up at night the organic matter breaks down and gets me my free co2,,,,,,, until I open the doors from the heat.

Give it a try, I'd be curious to see what your number is.

You (of course) are 100% right Dave and the CO2 reading in the morning with the bag removed overnight is a solid 850 ppm which is still 40% more than the regular outside reading. Fun experiment, I’m going to continue to use these Exhale bags until such time as I get a larger enclosed greenhouse, then I’ll upgrade.

Yeah, I noticed this when I tried co2. It's all the organic matter breaking down and giving us free co2. The only bad part is, it's at night when the plants don't need it. ugh..
