Plants need CO2 for breathing and for the photosynthesis process, the Pro-Leaf B1 CO2 Controller is a tried and tested unit for controlling the release of CO2. Without optimal CO2 levels, you will stunt the growth of your plants, impacting on the yields at 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.

The Pro-Leaf PPM-B1, digital CO² CONTROLLER, provides simple and precise control of a 240 Volt CO² generating device with modes for both increasing and decreasing CO².

Also featuring fuzzy logic operation which offers additional accuracy when utilizing CO² supplementation.

Adjustable set points range from 400-2000 parts per million (PPM) with an accuracy of +/-100 PPM and an adjustable deadband.

A remote sensor with 4.5m cable, accurately monitors the garden’s PPM levels and relays this information to the controller for display in real-time.

How the Pro-Leaf B1 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.

This Pro-Leaf CO2 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.


  • Max Current: 10 amps
  • Sensor Cord Length: 4.5m (15')
  • Control Range: 400ppm to 2000ppm
  • CO2 Accuracy: 100ppm
  • Weight: 1kg (2.2 lb)



The Pro-Leaf CO² regulator is simple to use and will allow you to regulate and maintain ideal CO² levels for optimal growth. The Pro Leaf CO² regulator includes a precision regulator flow gauge, industrial solenoid valve and 5 meters of plastic dispensing tube.

These regulators are particularly constructed to release highly controlled amounts of carbon dioxide gas.

They do this by releasing CO2 from the tank of the generator into a grow room to be taken up by plants.


  • Safely release up to 17 L per minute of CO².
  • Brass construction for long-lasting dependability and durability
  • Adjustable flow meter
  • High quality oil-less pressure gauge
  • Hose tail is suitable for 4.2mm inside diameter hose
  • Includes two plastic cylinder washers and 3.5 metres of CO² dispensing tube
  • Heavy duty solenoid valve and AU electrical plug
  • 240 Volts/50 Hz. Max input pressure 150 MPa.
  • Flow rate 0-30 L/min


 Easily replaceable CO² sensor to suit the Pro-Leaf B1 CO² controller. Plug and play.
