The LP/NG-10 is a high-output CO2 generator ideal for large indoor setups that require consistent and efficient carbon dioxide supplementation. Featuring 10 heavy-duty brass burners, it supports both liquid propane and natural gas, which can be easily converted using the included fittings. It includes 24V electronic ignition — meaning no pilot flame to deal with — a solenoid shut-off valve in case of ignition failure, and a tip-over switch. You can customize output by removing individual burner plugs or using the built-in selector switch. It comes ready to install — including a gas regulator, 5-meter gas hose, power adapter, and hanging chain hardware for flexible mounting on the ceiling or floor. For smaller setups, look into the Pro-Leaf LP/NG-4 — offering solid performance in a more compact option. If you need CO2 regulation for a mid-sized grow, the Pro-Leaf LP/NG-8 is perfect.
