The LP/NG-4 is a compact and efficient CO2 generator ideal for small to medium setups that need consistent CO2 enrichment. Featuring four high-quality brass burners, it operates on either liquid propane or natural gas — with included fittings for both. With 24V electronic ignition there’s no standing pilot flame. It also incorporates key safety features like a solenoid shut-off valve and tip-over switch. You can easily customize output by using the built-in selector switch or removing burner plugs. It also comes with everything growers need to set it up — including a gas regulator, 5m hose, power adapter, and mounting hardware for effortless floor or ceiling installation. For more power, check out the Pro-Leaf LP/NG-8 with double the burners. Growers running larger-scale setups may benefit from the Pro-Leaf LP/NG-10 — delivering maximum CO2 output with commercial-grade performance.
