Look, don't know if that works, but using CO2 properly is a real big chore. The advantages are minimal.

You need to be able to shut off the air exchange so they can absorb the CO2, plus then venting, plus this, that, and any other PIA set of rules that go with it.

In 20 some odd years of growing, I see no need for the CO2, only more work. I get great production without anything except Molasses.
