General question concerning growing Phaius'

[Paul Mc]

So I have two of them potted in one large plastic pot. One is very mature and I bought it last year in bloom and it has since grown two new growths. The other one was a baby when I bought it in mid-summer last year.

My question revolves around the baby. It did not grow at all this year. It is just sitting there asking me what it's supposed to do, lol... I'm confused why it's not growing when the mature one grew so much. Any ideas or thoughts on why this would happen?

On a side note, I bought one of the baby's for my friend as well. His has grown like crazy since I gave it to him.
