Why is your differential set to???

My guess would be that air/gas is escaping faster than it should = not a completely sealed room...

I run a 10x10 with co2 ppms @ 1000.... The valve will run for about 10-20sec then be off for about 20-30min and run again for another 10-20sec... My room isn't completely sealed either but it is about 97% sealed... I also use an oscillating fan to move air upward - my co2 hose leaches out right in front of the fan...
