Rotate 'em till it's a pita then tie to something. Moving the plant is like roasting a hotdog, rotating it to help it finish evenly on all sides. Mother Nature does it by the sun rising in the east and setting west. If you want back side development run some florescent tubes on the wall. Be sure to use the clear plastic bulb covers. HD.
Rotating or moving forces the plant to spend more time with it's leaves mis-aligned to the light. That's why people find a lower yield, or 'airy' buds. I'm amazed that such products like those automatic rotating devices actually sell. Rub a few brain cells together and it's obvious, really.

Thats why sog is so attractive. Build a solid plant canopy w/ no side branches and the light is easily spread and none are in the shade and you grow only colas. the major drawback is the high plant count and the expense of rockwool.
No matter how you slice it there is only so much coming out of any garden. Effort + Time + Expense= Yield.
