Electricity goes to solenoid.
In there, there is a coil, when the electticity goes through that is causes a magnetic field, this pulls a metal spool (which goes up inside it) to pull back, thus the valve opens. When power is cut off, theres a little spring that will push it back shut.
Have this on a timer in sync with your lights will work fine.
Use a seperate one for it though as I've been told its a good idea to turn the CO2 off 30mins before lights go off.
