Hey Bozo, looking good so far!

Should is right, the CFLs are fine where they're at. Not much penetration with flouros so the closer the better. The way to tell if the light is too close is by looking at the burnt leaves after you move the light up Seriously though, 1 inch away is perfectly fine and will show no adverse effects until it's literally touching the plant.

If the box is reflective on the inside you should be fine without any reflectors. In fact, and someone correct me if I'm wrong, CFLs focus most of their light out the end, not the side.

edit: I see that it's not mylar'd or painted, get that done asap. Should is right again, you're losing light to the brownness

On another note, I don't know about using a cardboard box as cab/tent/grow space. It just seems like a potential fire hazard that should be avoided, especially since it's YOUR house

Also, what type of soil/mix have ya got there?
