? about CO2 produced by a human

[Italiano715]

it probably won't make that much difference. first off, for co2 to be effective you need to have the rest of your grow dialed in. second, you need to run ~1500-1800ppm. for co2 to be effective you need to run it in a SEALED room. this is harmful to you and any pets that you may have.
