Product Description
Pro-Leaf CO2 Controller – Easy, Accurate CO2 Management for Bigger Yields The Pro-Leaf Controller makes it simple to maintain optimal CO2 levels in your grow room. Just plug it into a socket, connect your CO2 source (bottle or burner), and it’ll handle the rest—automatically adjusting CO2 output based on real-time data from its sensor. Boosts Growth & Yields: Increases photosynthesis with CO2 levels between 400–2000ppm Smart & Efficient: Built-in light sensor stops dosing during dark periods to avoid waste Simple Setup: Plug-and-play operation with a clear display and easy controls Accurate Monitoring: Real-time CO2 readings and dosing via external sensor (4.5m cord) Flexible Control Modes: Works with bottles, regulators, gas-powered CO2 generators, or fans Includes Everything: Controller, sensor, fixings, instruction manual, and 1-year warranty Photosynthesis thrives with higher CO2—up to 3x atmospheric levels—helping plants grow faster and produce larger fruits. Unlike guesswork methods, Pro-Leaf doses with precision using real-time data. Specifications: Control Range: 400–2000ppm Accuracy: ±100ppm Max Load: 10A Weight: 1kg Power: UK 3-pin plug Quick Setup Guide: Set your desired CO2 PPM and deadband (tolerance range). Choose your control mode: PPM Up for CO2 burners Fuzzy Logic for CO2 bottles PPM Down for fan-controlled reduction (optional) Use the Max/Min function to track CO2 levels while away. Note: Keep at least 2.5m from digital ballasts. Not compatible with sulfur vapourisers (remove sensor before use to protect warranty).
