Get precise CO2 control with a Pro-Leaf CO2 Controller. 

You can adjust the output from 400ppm - 2000ppm.  To prevent CO2 waste, dosing is restricted to lights-on, when plants use CO2.

You can use it with bottled CO2 or propane gas

  • Controls CO2 output (from 400ppm - 2000ppm)
  • Use it with bottled CO2 or propane gas
  • Day & night mode
  • 1 year manufacturer's warranty
Easy Operation

To get  started it's pretty much plug and play.

Day & Night Mode

To prevent CO2 waste, dosing only happens during lights-on. This is when plants use CO2

Self-Calbrating CO2 Sensor

You won't have to calibrator yourself , but we recommend doing so once a year anyway.

PPM Up / Fuzzy Logic PPM Down

This doses with CO2 in shorter bursts. If using a CO2 bottle this stops the regulator getting too cold (if the regulator gets too cold, it can stay open). 

Digital Display

It's easy to check your settings it a glance.

CO2 Disable Mode

You can connect your controller to an extractor fan. During the night to bring your CO2 level down, air is extracted. In closed loop rooms where air isn't typically extracted, it's ideal. 

Why Add CO2?

Plants use CO2 for photosynthesis (sugar production).

If CO2 is restricted, so is sugar production.

Plants can handle 1000 - 1200ppm of CO2. There's only around 400 - 450ppm in the air. Bringing that up to the optimum 1200ppm is one of the easiest ways to ramp up sugar production and increases your yield by up to 20%!

In summer, extra CO2 and also helps plants with heat stress by photosynthesising more!

How To Use

1. Put the plug in
2. Push the left button 1 time
3. Set the level CO2 level ( turn left or right to go up or down)

The Pro Leaf CO2 Regulator fits onto a CO2 gas cylinder, utilising a solenoid valve to distribute the gas as required. It is initiated and doses according to the user's preference as set on the Pro-Leaf CO2 Controller. The Pro-Leaf CO2 Regulator ensures that perfect levels of CO2 are maintained in the grow area at all times, stimulating your plants to grow faster and larger than ever before!
