Carbon dioxide (CO2) is one of the most heavily used gases in greenhouses because it’s a necessary ingredient for photosynthesis. Grow house operations supplement the atmosphere with CO2 to increase crop yields and make the most of their growing efforts.
Buying cylinders of CO2 is a safer route for supplementing greenhouses with this gas than other alternatives. Some operations may have carbon dioxide generators on-site that use fossil fuel combustion to create the gas. However, this method can also produce carbon monoxide and nitrogen dioxide — two toxic gases that can pose a risk to workers in the area. CO2 is available in high pressure cylinders, liquid dewars, microbulk and bulk supply systems.
