The TechGrow CO2 Generator 4kW (LPG) is a liquid‑propane–fired unit designed to raise and stabilize carbon‑dioxide levels in greenhouses and sealed grow rooms. This 4 kW model uses four burners and electric ignition, so there is no standing pilot flame, which helps limit gas use. Safety functions include a tilt switch that shuts the gas solenoid if the unit is tipped and an audible alarm when ignition fails. It runs from a 12 V power adapter and connects to a propane/butane cylinder via a regulator and hose. TechGrow recommends pairing the generator with a compatible CO2 controller to maintain a setpoint.
