You need a regulator with a solenoid switch to turn off and on the flow.

This set up is 76.99

You could use a timmer but that is not the best thing. For the best results where you dont waist the gas is to use a monitor/controler

That one is 350.00 bucks. This is not cheep stuff but it is some of the best. The one I use is the C.A.P. XGC-1 Xtreme Greenhouse Controller it regulates the whole environment...but they cost about a grand each.
