Plants need CO2 for breathing and for the photosynthesis process. Without optimal CO2 levels, you will stunt the growth of your plants, impacting the yield and harvest. Research has shown that providing CO2 levels between 1,000ppm and 1,300ppm can increase the yield by up to 30%.

Investing in a CO2 controller will therefore pay dividends for years to come.

How the PPM CO2 Controller works

  • Select your desired minimum CO2 level in PPM.
  • The unit will switch on the power outlet when the CO2 level goes below this value.
  • The switch triggers a CO2 Regulator Kit (not included), which then releases CO2 into the atmosphere of the grow area.
  • When the CO2 sensor (included) senses more than the CO2 PPM minimum level, the switch turns off.

The controller is the updated version of the D1 model, and comes with an Australian power socket and plug. 

The built in photocell will activate the controller during daylight or while the grow lights are switched on, turning itself off in darkness.
