Maximize Growth & Yields with a Johnson CO2 Generator

A Johnson generator equipped with our new PPM controller counter balances plant respiration in all conditions to optimize yield and bloom quality by maximizing CO2 levels – up to 1,500 PPM.

  • Easy to hook up and program 3 units at one time
  • Controls the PPM in the greenhouse during light hours
  • One plug hook up is compatible with all Johnson CO2 generators.
  • Most growers do their own installation. No expensive duct work is required.
  • New purchases come with a burner lifetime warranty.
  • Simply set the gas pressure gauge to completely automate the desired CO2 levels in your greenhouse.
  • The 24V gas valve can be activated by a timer or an optional combination timer thermostat.
  • In case of flame failure, the gas supply shuts off automatically.
