Hey Tacman7,

You're welcome!

Here's some of the frame pictures for you. The idea was to overlapping joints to prevent light leaks. all 2 x 4s, 3/4 plywood for horizontal surfaces, 1/2 plywood on back, sides and doors (everything vertical). I used outdoor deck screws to fasten it together.. If I were doing it again, I'd size it for an 8 tube t-5 like your using. Less heat and your right, you can put them right on top of the plants.. Not sure where you live, me in the Pacific NW.. The first year with the box, I ended up shutting down for about 6 weeks in the summer and restarted in the fall.. but it is a lot easier up here with cooling since it normally doesn't get hot very long in the summer. Also, since I lived rurally I was able to vent my box through the garage wall by putting in another dryer vent.
