The carbon dioxide enrichment system designed for this structure after some data collection which is why there are two bottles. The larger bottle is a 50lb and this is the main source of the carbon dioxide enrichment. This system ups the internal carbon dioxide enrichment to about 900ppm. When the temperature increases and the large yellow exhaust fan comes on this system turn off. However, it was noticed that when this was occurring the CO2 levels were dropping below 300ppm which can stunt plant growth. So, an additional system was installed that helps maintain the growing environment at normal ambient levels of 400ppm. Since this system does not run as often or need as much CO2 the smaller 20lb bottle is used for this controller.
