You know that a regular lighting schedule is also necessary to prevent hibernation attempts? (It's come up a few times on the board recently.) You only need a basic timer; you can pick one up at the hardware store (or pretty much anywhere once Christmas decorations invade every general store!) for $5-$15. You can also get really fancy ones with multiple light settings, lots of plug-ins, blah blah blah, but you really don't need it. Just something that goes on-off every 12-14 hours!
