Pro Leaf delivers solid output at a fraction of what you'd spend on refillable CO2 cylinders long-term. The build quality is straightforward, the safety features are there, and propane is cheap and readily available.

It converts LPG into carbon dioxide on-demand, raising room levels to 800–1200ppm — the sweet spot for driving faster photosynthesis, heavier plant vigour, and yields up to 20–30% higher than ambient CO2 levels. Available in \u003cstrong\u003e4kW and 10kW models\u003c\/strong\u003e, it's built with electronic ignition, stainless steel construction, and safety features that mean you can leave it running without babysitting it.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eCO2 burners sit in a different category to bottled CO2 systems.

Position at least 18–24 inches away from walls and flammable materials. Place an air circulator fan next to the unit to push CO2 evenly throughout the room. Keep it away from exhaust fans — if your extraction is pulling air past the burner, the CO2 goes straight out and you're wasting propane.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAutomated control (recommended)\u003c\/strong\u003e\u003cbr\u003ePair with a Pro Leaf CO2 Controller (sold separately) for hands-off operation.
