Well mine keeps growing and I'm facinated watching it because I have never had an orchid with psudo-bulbs (well not one that has actually grown).
There were four new growths starting when I got it and each of them has grown lots and the largest two are definately forming the psudo-bulbs now. (I can see them forming inside the leaves when you hold it up to the light).
There is also a fifth new growth which keeps getting bigger but is still quite small.
As mine is mounted I'm also watching masses of roots forming near every new growth.
No sign of spike yet and with the cold weather now I'm not expecting them for a while now. But I'm loving growing it.
