RSJ, I've often heard people say that one plant or another will "do better" if it's pot bound. To be honest though, at least in my experience, I haven't seen a shred of difference. Pot-bound plants got that way because they were growing well before that condition arose, so if your plant is doing well, it should bloom nicely. The Zygos here aren't pot-bound yet, but they will be soon. I have no complaints whatsoever about how they bloom, and no pot-bound plant I ever grew spiked longer with bigger and more flowers just because it was pot-bound.

My 2 cents....
