First of I'm not gonna try this...
but only because I don't have the room to do so.


I would think that starting off with very young plant and bending it into a second pot as early as possible could be beneficial. Imagine a plant stretched out roughly three foot long with lighting above, below, and on each side.

If more light equals more growth is true and the plant is able to take in nutrients from both ends then I see this as being a win win situation.

And if not? Oh well. No mistakes, only lessons learned.
