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.

headshake Reviewed by headshake on . ? about CO2 produced by a human So the question is...... If I am sleeping in a 15' X 12' room, the same room contains my 12/12 box, anyone know how many ppms CO2 I can add to the room by sleeping in it for 6-8 hrs ???? or does anyone know of any formulas for ppms produced by the average human?? and is this even enough to make any significant difference? Thanks for the help! Rating: 5
