My own plan is for fewer, larger plants lining the walls of the vertical cylinder, each growing out of a 27 gallon tub site in an RDWC. The current plan is for each of these plants filling in a trellis that's 4 feet tall and 6 feet wide. The whole cylinder would be 4 feet across. Two plants should run an elbow plus each. I'm hoping for two each from one thouie.
The light mover part is what is really new, though. I haven't seen anyone else try it besides me- and mine isn't up and running yet. I would like to see a more detailed explanation of how your mover works.
I bought a small dc powered hobby motor and a reversing switch. The motor will wind the cord holding the bulb up until the reversing switch is tripped, and then it unwinds all the way- and winds back up, hitting the reversing switch again... mine will move the full 4 feet up and down. I may look into supplemental spectra to put at top and bottom.
I'll have a fan blowing air from the floor up, one of those fans with a rotating face to deflect air, have it soon and blow air on the canopy. The cylinder naturally allows for shedding heat, so temps will be well controlled top to bottom.
