Reflective walls, and set up!

Right, so after getting some beautiful daylight CFLs and a short circuit I performed with a knife trying to screw a screw into a loose socket, my complementary indoor setup is up! I just needs to DIY my reflective walls.

I also need to know how close I can get the plants to the lights before I burn them? They are about 1 inch away. I can put my hands as close to the lights as I want and it only hurts if I touch them.

I'm also thinking of taking the mesh out of the windows to increase airflow and ventilation but I'm sure I will be getting lots of bugs if I do, what do you guys think?

With 3 x 23w CFLs would you reccomend another aluminum tray to put sideways or some white cardboard on styrofoam?

That setup will cause you nothing but heartache! Need light...need more light...
Hold the leaves between your thumb and forefinger to see if they are warm to guage if the light is too close. any light 1" away will cause problems. Weird, irreversible problems.
Aluminum reflects lots of heat and has lots of hot spots so be careful! I suppose the white styrofoam would be helpful but very inefficient.
Need to throw a couple hundy at it...
