Those are some super sweet looking ladies DG! I think Whadeezlrg is correct, there is one LVPK cut and she is a champion, hopefully one of my seeds will be her equal but right now that cut stands above everything else I've grown.
The Holodeck is covered walls and ceiling with Prodex. It is super great stuff reflective on both sides, light proof, and a 98% radiant barrier, and too many other good spec to remember.
It comes in 700sq' rolls 4'x175' the stuff is wonderful.

I would recommend it to all of you it is way better than mylar, bubble insulation, and panda plastic.
