How do I add CO2?

  1. I have a 11 cubic foot closet and I don't understand how to put CO2 on a timer. Could someone give me a hand? Thanks a lot.
     
  2. What equipment do you have so far?
    What are the dimensions of your box?

    To add 1200ppm co2 to the grow (it will already contain 300ppm from the air), will bring you to 1500ppm.
    It will take a regulator that is capable of putting out 1CFH.
    Set at 1CFH, and allowed to open for .79 minutes, will fill an 11CuFt box to 1500ppm.
     
  3. The dimensions of my box are 2.3ft x 1.4ft x 3.5ft= 11.27 cubic feet.

    Can i use a 20oz. CO2 bottle from a paintball gun? If so, thats the only equipment I have. I have actually seen one of your posts about the CO2 setup but i dont understand how to actually put it together. Also, my temp is usually around 85 degrees, so do you think that adding CO2 would help a lot?
     
  4. co2 helps best if all other conditions are also optimal. Light, temps, ferts, ect...
    A 20oz will call for alot of refills my man. Pretty hard to do, considering a 4x4x4 room will use about a 20LB tank in a month if venting, and 2-3months if sealed.
