Pro-Leaf CO2 Controller & Sensor
The Easy Way to Maintain Perfect CO2 Levels
The Pro-Leaf Controller makes optimising carbon dioxide levels as simple as possible. Just plug it into a power socket and plug your CO2 source (either a burner or bottle) into the Pro-Leaf. You can then monitor CO2 concentrations and automatically maintain optimal levels. With a built-in light sensor, the Pro-Leaf will even stop dosing during dark periods. This is a highly impressive piece of kit that will help you to push your yields to the next level.
- A plug-and-play solution that monitors CO2 concentrations in your grow room
- Automatically releases CO2 when needed in order to achieve optimal levels
- Helps to maximise photosynthesis rates, for faster growth and bigger yields
- Allows you to choose settings between 400ppm and 2000ppm
- Very easy to program, with a clear display
- Comes with a built-in photocell to check for dark periods
- Doesn't waste CO2 - only doses when necessary
- Supplied with the parts needed to mount the controller and hang the sensor
- Teams up nicely with Autopilot CO2 Generators or the Dimlux CO2 Regulator
- Comes with a one-year manufacturer's guarantee for complete peace of mind
- Can be connected up to a fan, in order to bring CO2 levels down (if necessary)
- Now comes with a UK 3 pin plug as standard to power the controller.

How the Pro-Leaf CO2 Controller Works
Photosynthesis is the process where plants use light energy from your grow lamp (or the sun) to take carbon dioxide and break it down into carbon and oxygen. The carbon is then used to manufacture essential plant sugars and the oxygen is released as a by-product. To achieve the best results, the bulk of growers' efforts should be channelled towards ensuring that plants photosynthesise as effectively as possible. The first thing to do is to ensure that environmental conditions are optimal, with moisture and temperature levels that allow leaf stomata to remain open. Once your environment is nailed down, you can push things to the next level by increasing the CO2 content of the air. Typical levels are around 360ppm, but plants can handle at least three times that level before they become vulnerable to toxicity. With more CO2 to hand, plants are able to produce more sugars, which speeds up overall growth rates, causing fruits to swell up in size. It comes as no surprise, then, that CO2 supplementation is used extensively in the professional horticultural industry.

The Pro-Leaf CO2 Controller and Sensor represent one of the simplest ways to maintain perfect CO2 levels at all times. In the past, CO2 dosers effectively guessed how much CO2 to add based around the dimensions of your room. The Pro-Leaf, however, gathers CO2 concentration data using a sensor, which then allows it to dose accurately based on real-time conditions. All you need to do is hang up the sensor, plug the controller into a wall socket and plug your CO2 source into the controller. Then choose your settings and you're away... The Pro-Leaf can handle both bottle / regulator set-ups and gas-powered CO2 generators.
Max Current: 10 amps
Sensor Cord Length: 4.5m (15')
Control Range: 400ppm to 2000ppm
CO2 Accuracy: 100ppm
Weight: 1kg (2.2 lb)
How to Use the Pro-Leaf CO2 Controller
Clear and concise instructions are included in the box. Here is a rough overview:
1) Press the PPM knob (on the left) and select your PPM setpoint.
2) Press the 'Deadband' knob (on the right) and select your deadband level. Deadband works in a similar way to hysteresis. It decides how far you are willing to let the PPM deviate before automatically correcting the situation. The smaller the deadband, the quicker the unit will respond.
3) Choose a 'control mode' setting using the switch on the bottom right-hand side. 'PPM Up' is used when you are increasing CO2 levels with a gas powered generator. 'Fuzzy Logic' should be selected if you want to use a CO2 bottle and regulator. 'PPM Down' is used when regulating fans, so that they kick in when CO2 levels get too high. This option will rarely be used in most grow rooms, because the priority will be increasing CO2 levels.
There's a 'Max / Min' feature that will tell you what the maximum and minimum PPM levels while you were away. All you need to do is click both buttons simultaneously.
Always keep the controller at least 2.5 metres away from any digital ballasts.
The Pro-Leaf cannot be used alongside a sulfur vapouriser. Failure to take adequate care of it will invalidate the warranty. If you do wish to use a sulfor vaporiser, ensure that you remove the sensor from the affected area first.
