couple things.

1. first and foremost you need to have some ventilation in there bro. i dont see any fans exhaust or intake. or even just stationary. you're really going to want to read heavily on ventilation, it is something you most definately don't want to overlook.

2. i know you said this is just a "test" run, but i'm sure you can afford a few extra bucks at wally world for another 4 pack of cfl's. and a couple more of those 2 socket adapters. you will thank me in the end when your bud are a little more dense than just the 2 cfl's.

on top of the other couple things mention above, i think you're on track man.

good luck with the grow.
