Sit on it and ROTATE

[desertdan]

The sun will do what you need naturally. The sun does not move in a straight line across the sky. It moves in a wide arc. Depending on the speed of turning, you might only get light on one side with this method. I have thought about this a lot as a way to keep some thing in shade all day.

The plant will gravitate to the sun- I have a window sill grow . I started moving around and then stopped-

The plant repositioned all the bud sites to get the most sun - it looks like a wall of buds where the buds from the back have moved to join the others on the window side of the plant.
