Master your Carbon Dioxide levels with the Pro Leaf CO2 Controller. Designed for use with Carbon Dioxide bottles or burners, this precision piece of grow room equipment monitors CO2 ppm and controls supply. In doing so it helps to maximise the effectiveness and efficiency of your CO2 inputs.

Pro Leaf Monitors

Firstly, the Pro Leaf monitors CO2 ppm. As the unit is sensor controlled there’s no estimating of levels according to room size. This controller takes exact readings based on actual ppm, making it far more accurate than other CO2 dosers. Better still, the Pro Leaf is self-calibrating and plugs straight into your mains supply, so it’s up and running in minutes.

Pro Leaf Regulates

When the CO2 ppm in your space hits your preset minimum or maximum levels the Pro Leaf then automatically activates or deactivates your bottle or burner.

Because CO2 is ineffective during hours of darkness your supply should always be off during ‘lights-off’. The Pro Leaf knows this thanks to its light sensor and will, by default, keep your supply shut off when your room is not illuminated.

Why regulate CO2 levels?

Whilst CO2 is an exciting and high-potential growth and yield-enhancing input it is also of limited use beyond certain levels. Natural, background levels of CO2 are around 400ppm. Plants can use anything up to around 1200-1500ppm. But anything beyond that is essentially useless. So having the Pro Leaf to keep your supply ‘on point’ really helps reduce waste.

Hassle free indoor gardening with CO2

The Pro Leaf also performs an important safety function. Within reason, excess CO2 is not harmful to plants. But it is harmful to humans. By capping the levels in your room, the Pro Leaf helps ensure that your indoor garden is safe for yourself and your neighbours.
