I just added co2 too my garden and am wondering @ how long between on/cycle should I be able to go? room is 490sqft and sealed pretty well. I know it takes 38m set at 1cfh to reach optimum levels but @ how long is it possible to stay at that level?? Im wanting to save on co2 but still boost yeild.......My timer is max 20m on/time so I am running higher cfm to keep within timer specs. plus Ive heard its best to get levels up quicker is better but I dont see how long to go between cycles???

it all depends on your air flow if youre turning off your exhaust and leaks

Dude, save yourself allot of guesswork and even more wasted Co2 by getting one of these: http://www.horticulturesource.com/product_info.php?products_id=9189

You will also prevent toxic levels of co2 from forming. I have a 530 cubic foot sealed grow room and I spend more on co2 than nutes per grow. #20 lasts a week with a precision fuzzy logic controller. $17 a week for 9 weeks =$153. Worth it in yield but also way worth it do have a decent controller. Plug in and forget about it.

Just a thought.

I have a bottle setup on a timer with no ppm meter. My flower room is 10' x 7' and I set the regulator at 0.30 and the timer is set to run for 15 min every two hours. My 20 lb. bottle lasts a month. 1500 ppm is ideal any more would just be wasted. Your plants requirements for nutrients will also increase with the raised CO2 levels. In my first full run with CO2 I was able to attain a 30% increase in yield.
