Nice plants!! I love the stealth door.

You might want to move the lights a little closer. Light fades the sqaure of the distance I believe. So a foot away they're getting 4x as less light then being directly under it.
With cfls you can get pretty close. I have a 100watt cfl grow light that I put right on top of my plants to keep them from reaching for the light. Keeps em short and stacked.

I've always have gone straight from 18/6 to 12/12 without any problems. Well my first grow hermied but that was from my power strip light. didn't even think of that little light D'oh.
