It should have a multi-tap ballast.

Have you tried removing the bulb and hooking a multimeter to it? Green is generally earth ground.
It looks like its wired for 115 volts, but the ballast says 270v (240). 240 volts uses two hot wires, and one ground (green). 115 volts uses one hot wire, a neutral wire (white), and a ground (green). The ground is always green, and the neutral is always white. Hot wires can be any number of other colors, just not green or white.
You would have to take the cover plate off of the junction box (box the cord goes into) on the ballast and look at the connections, and hope it's labeled in some way. If it is a multi-tap ballast it will have connections for 115v or 270 (240).
Please use extreme caution when it comes to electricity, please. It can be very dangerous so if you aren't sure, don't do it. I'm sure I don't have to stress that but I work with electricity daily and have much respect for it.
If you can take a pic with the cover off, of the wiring diagram that would help us help you.
If you heard humming chances are it might be wired 115v already, but then again I've never wired a ballast wrong so I'm not sure if it would hum under partial voltage. If it is 115v as well, you will need a 3 prong 115v cord so you can use the ground wire as well. 14 gauge to be safe (that's the thickness of the wires in the extension cord).
Hope this will help you get started on your grow!
Must agree with Dank. And for you others out there, 277 is 277, single phase (like 120 single phase) 2 or 3 phase of 277 is 480 (120 = 208.... 240 derives from a transformer tap at the utilities' transformer that isn't usually available at a residence...
