CO2 Calculator


 

Calculate how much CO2 will be needed to fill a grow room to the optimum level.  It will also determine how long it will take to fill at the given rate.

Usually you would want to refill just after an exhaust cycle, every 3 hours for 30 minute intervals with the lights ON.

*The air already has about 300 PPM so you only need to add 1200 PPM more to get the optimum level of 1500 PPM.
