This is the simplest way to inject CO2 into your grow room. Just tell it the size of your room and the controller does the rest. The Unis CO2 release kit features a pressure gauge, which will gauge the amount of CO2 in the tank, a solenoid valve which will turn the unit on or off and a flow meter which determines the amount of CO2 released. The Unis CO2 release kit has been designed with the latest state of the art microprocessor technology which allows 16 individual settings for room size. There is no requirement to alter the flow rate of the gas regulator which is factory pre-set to match the controller making set up and use extremely simple.
