CO2 Generators & Burners for Grow Room Enrichment
CO2 generators (burners) produce carbon dioxide through the combustion of natural gas or propane, releasing CO2 into the growing environment as a byproduct of the combustion reaction. For large commercial greenhouses and indoor farms where compressed CO2 tank refill frequency becomes impractical, burners provide a cost-effective continuous CO2 source that scales with facility size without logistical constraints.
How CO2 Burners Work
CO2 burners connect to a natural gas line or propane tank and combust the fuel in a controlled burner element, releasing CO2 and water vapor into the grow space. A CO2 controller monitors ambient ppm and signals the burner to fire when CO2 drops below setpoint, shutting off when the target is reached. Burners are available in multiple BTU output ratings matched to different room volumes — a properly sized burner cycles on and off to maintain the target ppm rather than running continuously. Natural gas burners are the preferred choice for facilities with existing gas infrastructure; propane burners are used where gas lines aren’t available.
CO2 Burners vs. Compressed Tank Systems
CO2 burners produce heat and water vapor alongside CO2 — byproducts that add to HVAC and dehumidification load in an already warm growing environment. For sealed grow rooms and grow tents, compressed CO2 tanks deliver clean CO2 without thermal or humidity side effects and are strongly preferred. Burners are most practical in large commercial greenhouses with robust ventilation and climate control infrastructure where the operational economics of continuous CO2 enrichment favor a combustion source over frequent tank replacement.
