smokinlowrider4u Reviewed by smokinlowrider4u on . Ventilation! Why do i need it? Okay so plants breath co2, right? If my plants are in an enclosed area, with co2 filling the area. And Carbon Dioxide is heaver than Oxygen, than I can keep an all co2 environment, I mean as long as you have an open top for the O to get out. Or am i totally out of it! Rating: 5
