The CO2 Release Kit is one of the best ways of injecting CO2 into an indoor growing environment.
The CO2 release kit features a pressure gauge, which will gauge the amount of CO2 in the tank, a flow meter which determines the amount of CO2 released (set by the user).
The kit will only act as the vessel to allow the physical release/injection of CO2.
A timer will need to be purchased separately if required. It is a good idea to use a precision timer (such as the Compugas) in conjunction with a release kit as it will optimize CO2 levels & avoid any excess wastage of CO2.
The kit comes ready assembled & all you will need to do is attach it to a suitable "vapour" release CO2 bottle.
