Walmart has them for sure. In Arizona it's the same isle as the extension cords and light bulbs. They look like this (attached). Just make sure you get one with a ground plug (center prong below the two blades) if you can. Not the biggest problem if you can't, but it's a nice safety feature and pretty important if you get or have an HPS system.

They're not much.. just a few bucks. Maybe $5 ?

You set what hours you want it on. Like mine goes off at midnight, and then back on at four in the morning. So that's twenty hours on, and four off.
