CFL grow box help

I just wanted to post this link here so I could get a little more feedback. I posted in the room design forum. I figured maybe the CFL guru's would be able to give me some input.

You're talking about light placement. One of the advantages of using 42s is they are easy to move around. You will use both of those configurations and a lot more. Plan for that. Try to make it so you can hang a light anywhere it needs to be and direct it anywhere it is needed. I use a pvc frame that I can adjust almost infintely and then hang a clamp reflector almost anywhere on it.
