Does anyone know where to find the formula you use to see how many cubic feet per hour to release? I have the tank, regulator and timer method... My grow area is 7'X8'X7'. It's sealed with a window ac, the cooltubes are vented in/out. There are 2 wall mount 20" fans to circulate.. it keeps a constant 78 degrees with 45-55 RH..

| The formula just says co2 on for 35 mins at one cubic foot per hour for my situation... Does that mean 35 mins on per hour; i.e... 35mins on 25 mins off. Or does it mean 35 mins on then 60mins off? The formula doesn't tell you

| It doesn't calculate how fast it is used or leaked. Best way would be to set up an exhaust fan that runs right before the Co2 so you have a fresh start every hour. You should also fill the room as fast as possible other wise your room will only be 1500ppm for 30 minutes... | ||

| If I do not have a controller that monitors ppm, I go with this: timer regulator tank. Set the timer for 30 min right before lights go on. Then run 15 min every hour. done easy as that. If you have a controller, just set it at 1500 ppm.
