I've been barking up that same tree, but I can't find shit!
I'm playing with a new design (in my head). The lights are stationary, the "cabinet" is cylindrical, but the plants sit on a motorized "Lazy-Susan" powered by a bar-b-que rotissary motor. I figure it's easier to move the plants than it is to move the lights! The biggest stumbling block for me is figuring what "R.P.M." to use. Somebody out there must be up on this info!
