A simple to use, plug and play CO2 controller which ensures precise dosing from both bottled CO2 gas as well as Propane. The Pro-Leaf CO2 Controller allows you to adjust the output from 400ppm up to 2000pm. It features a highly accurate light sensitive measurement probe that only doses CO2 when your lights are on so there is no waste. The Pro-Leaf is recommended to only be used in 'sealed' grow rooms as it controls the level of CO2 by a set ppm, for those running an extraction system this would mean an amount of the released carbon dioxide would be sucked out of the room so the controller would always be fighting against this and therefore constantly trying to dose the room, using a lot of CO2. How To Use Pro-Leaf CO2 Controller To use this controller you will also require a Pro-Leaf CO2 Regulator. Plug the regulator into the controller and attach to your chosen gas bottle, be sure to use the supplied washer and tighten with a spanner for an air-tight seal. Position the setup in your room (some prefer to place an air movement fan in front of it to help move the gas round the room better) and place the sensor in a central location around canopy level. Plug in the unit and select your chosen ppm level using the dial, for most grow room situations we recommend a CO2 level of between 1000-1200ppm for the best results. Now fully open the tap on the regulator and your Pro-Leaf will start to dose your room with growth boosting carbon dioxide. Show more
