400w HPS and Flowering Stage- Any advice?

Just ordered a 400 watt HPS setup complete with reflector hood, ballast, and bulb. I'm beginning the flowering stage soon, and need to use a timer to regulate light and dark while I'm away. Will a basic timer work with my HPS? How can I be sure? Any advice or help is greatly appreciated!

Here's my grow!
