Pro-Leaf CO2 Controller
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. For most grow room situations we recommend a CO2 level of between 1000-1200ppm for the best results.
To use this controller you will also require a Pro-Leaf CO2 Regulator to connect to your gas bottle.
