6-8 is really close for a 400hps. Im am very impressed. I usually have mine around 16 inches. The more light the better so some milar or something would be good.

if u were to put nething reflective in i would only put it on the botttom. That small of a box i wouldn't worry about lining the hole thing

Are you putting the HPS in a cardboard box? Is that wise?
