Pro Leaf CO2 Burner is a professional LPG-powered CO2 generator designed to enrich larger grow rooms with consistent CO2 levels, helping plants photosynthesise faster and push harder under intense lighting. When running high-powered grow lights, plants can rapidly deplete available CO2 inside the grow environment. Supplementing CO2 to around 800–1200ppm can significantly improve growth rates, flowering performance and overall yield potential when environmental conditions are dialled in correctly. The Pro Leaf CO2 Burner offers a cost-effective alternative to bottled CO2 systems, making it ideal for larger sealed or semi-sealed grow rooms where bottled gas becomes expensive or impractical. Feature Details Fuel Type Liquid Propane (LPG) Available Models 4kW and 10kW Recommended CO2 Range 800–1200ppm Coverage Area Up to approx. 90m² (4kW) or 220m² (10kW) Construction Stainless steel body with brass burners Safety Features Flame safety shut-off, solenoid valve and tip-over protection Why Add CO2? Plants use CO2 during photosynthesis to convert light into energy. In sealed grow rooms running powerful LED or HID lighting, natural CO2 levels can quickly become depleted, limiting plant performance. Increasing CO2 levels allows plants to photosynthesise more efficiently, particularly under higher light intensities, often resulting in: Faster vegetative growth Improved flowering performance Better tolerance to heat and intense lighting Stronger nutrient utilisation Higher potential yields Many growers target around 1000–1200ppm during lights-on periods for maximum benefit in sealed environments Built For Larger Grow Rooms The Pro Leaf CO2 Burner is designed specifically for larger sealed or semi-sealed rooms where bottled CO2 becomes expensive and inconvenient long term. The burner uses propane gas to generate large volumes of CO2 quickly and efficiently, making it ideal for commercial spaces or advanced home grow rooms running multiple high-powered fixtures. The 10kW model features selectable burner control, allowing growers to operate 2, 5, 7 or all 10 burners depending on room size and CO2 demand. Professional Safety Features Safety is critical when using gas-powered CO2 systems, and the Pro Leaf Burner includes multiple built-in protections for safe operation. Electronic ignition system Integrated flame safety cut-out Solenoid gas shut-off valve Tip-over safety switch CE certified construction The intelligent ignition system removes the need for a constantly burning pilot flame while helping maintain safer operation inside professional grow environments. What You’ll Need Propane gas bottle CO2 controller and sensor (like the proleaf controller) Air circulation fans Proper ventilation and environmental management For best performance, pair the burner with a CO2 controller to automatically maintain target ppm levels throughout the light cycle. Included In The Box Included Components Gas regulator 3.66m gas hose Hanging hardware Power adapter Metal support feet Important Notes CO2 enrichment works best in sealed or semi-sealed environments where temperature, lighting and humidity are already properly controlled. Because CO2 burners also produce heat and water vapour, proper airflow and environmental management are essential for safe and effective operation. This product is not normally stocked in-store.
