CO2 Bottle Regulator
This is a brand-new bottle which has about 1000 psi or about 7000kPa of pressure. This will change over the course of the heating of the day, but when a new bottle is installed these are the expected values to ensure a truly full (50 pounds) of CO2 is ready to go.
The flow rate is adjusted to be around 9 cubic feet because if the flow is to fast it can lead to regulator freezing even in the hot greenhouse environment. Also, a low flow rate would mean it would run all the time and not allow for the structure to reach the pre-set 1000ppm level.
This is attached to 100ft of rain tubing, which is small diameter tubing with basically pin holes in it at regular intervals. This is placed on the ground in a large triangle shape under the leaf canopy to allow for even distribution to the plant. In addition, a fan is running to help keep the CO2 mixing around the plant.
Considering the entire system, it seems the regulator is the weak point as more than one of these has failed. Despite purchasing the “higher end” regulators and changing brands there seem still to be issues. As a result, a few spares are kept on hand to allow for a quick change if needed.
