i started today with a sealed room. i bought a matador co2 moniter, $1000. a kenmore dual hose portable a/c $800, i have a green-air cd6 i traded 3oz of outdoor for. the room seems to have 1000ppm co2 with out the gen on. i got the matador set for 1100 ppm, and intend to raise it it gradually to 1500ppm
