The Blueprint CO2 Generator NG, CGNG-2, features two preinstalled brass burners that generate 5.4 cu ft/hr of CO2 using natural gas. The removable second burner makes it easy to reduce the CO2 and heat output to suit a smaller growing space. The Generator features electronic ignition and dual solenoid valves, which eliminate the open pilot flame and provide safe, reliable starts. A safety tip-over switch automatically stops gas supply to the burners if the unit is not upright. Includes gas regulator, 12’ hose, hanging hardware and a three-year warranty.
