Pro-Leaf CO2 Controller

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 CO_2.

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-Calibrating CO2 Sensor

You won't have to calibrate it 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)

You'll also need to generate/release the CO_2, control the release (regulator) and detect CO₂ levels (analyser / sensor). For this will you need:

Equipment needed (Bottled CO₂)

1. Bottles of CO₂ gas - available in all shops

2. CO₂ Regulator (with Solenoid valve)

3. CO₂ Dispersion tubing (optional)

4. CO₂ Controller with inbuilt sensor / analyser (e.g. Pro-Leaf & 2-3 Pin Plug Adaptor & 3-2 Pin Plug Adaptor)

5. Power lead / cable fitted with plug

Equipment needed (LPG)

1. Propane canister (red / orange) - available in most petrol stations or garages 

2. LPG Generator (e.g. Pro-Leaf or AutoPilot)
3. UK Propane Regulator (Low Pressure) - should come with the canister

• 1/2 bar regulator (with 4kW Generator)
• 1 bar regulator (with 8kW or 10kW Generator)

4. CO₂ Controller (with inbuilt sensor / analyser (e.g. Pro-Leaf & 2-3 Pin Plug Adaptor)

5. Pipe cutters

6. Leak detection fluid

7. Hose clamp / gas hose clips
