CO2 Controller Dose 2

A controller designed for carbon dioxide release from a CO2 cylinder (not included). It features an adjustable internal timer, calibrated for various grow room dimensions. The only action required is to connect the controller to both the power supply and the CO2 cylinder, then adjust the timer according to the greenhouse size. They also provide a table with a wide range of room sizes, making it very easy to determine how much you need to use, and they show us how to install it correctly and easily.
