Carbon dioxide usage is often a topic of many questions so here is what the regulator in action looks like. There is the dial that reads the pressure in the bottle (which will change with temperature) and above this is a clear column that has a green ball. When the CO2 is flowing the rate can be adjusted and the green ball indicates how quick the CO2 is flowing. Too slow and the target level will never be reached and too fast and the regulator will actually freeze up. (Yes, even in a greenhouse as the CO2 as a strong cooling effect.)

So, running it at about 7 cubic feet per hour rate seems to be the sweet spot. This is controlled by the Atlas 8 controller and this system has worked out very well.
