Here are pics of my trusty growing rack in the basement.
I have everything tied to a regular timer like what you get in the lighting section ($12?). If you have a ton of fixtures, you can just put the power strip on the timer and wire the fixtures to the power strip.
I do two light fixtures per rack. They're on chains draped from eye-hooks, using cheapy chain and S-hooks from the hardware section. This way I can keep the lights less than an inch off the top leaves, both for heat and light saturation.
I run my timer on 20 hours on, 4 hour off for veggie seedlings. I run 18 on / 6 off for cuttings.
Here are pictures. If you need closeups of anything, let me know. I'm happy to snap some off. These are crappy Blackberry photos.
