I've seen that you know your Co2 after reading around the forum. I have a 3x3x5.5' enclosure with particle board (1 layer), I calked every corner and crack. I sealed the door with rubber stripping and added clamps so it's air tight as well. My question is, this is in a bedroom. Will dangerous amounts of Co2 leak through particleboard? For this size grow should I choose a timer over a regulator?
Thank you,
