Just wait till you guys see what Ive rigged up, Its a lazy susan I built from a cabinet caster with a low torque 12V motor geared down and with a rubber wheel that cranks the lazy susan around at about 3 rev per minute.... holy damn this thing is awesome I can stand on it and it keeps chugging. I got 5 more in the works, can whip em together in about 2 hours each, total cost is about 20$ each. Now Im thinking I can lean these things on a 20-25 degree angle with the plants on them, and hopefully the constant changing sideways gravity will make them want to bush out and not stretch(I have 10 sativa seedlings right now). I have no research to show that theory would do anything good... probably isnt too many people out there that have tried it... you can all look forward to seeing how such a technique works out as Ill be doing a side by side with most at 20 degrees off 90 and one control straight up and down. Im not even going to do a control of one not spinning, because Im pretty confident this is going to do wonderfull things. Also if you consider with leaning the plants 20 degrees you can get the top cola alot closer to the vert light.
Ill have at least a 400w MH and a 600w HPS and as many plants as are female around them in a 4x6x7. If I can control temps with both those lights running and feel i have good temperature control I will put in a second 600w HPS for flowering... so a ton of light for 4 or 6 plants.
