Hi Jim,
I am glad you asked, I forgot to update this thread... 2 years later the plant is doing really great ! It grew a lot of new leaves on each fan, bloomed last summer (1 spike) and is growing at least 3 spikes this month
Here are a few pics to illustrate this.
I offered a division of this plant to my parents in 2009, in a small S/H pot, and it is also doing great.
As you can notice on the picture, the plant is in a high pot, so the top third of the pellets dries up very quickly
As for the culture, I spray the plant every day during growing season, in order to get the top of the pellets moist, water heavily once a week with a 125 ppm N solution, and in late fall, I flush several times the pot with clear water, empty the reservoir at the bottom, and let the whole pot dry in a cold room and bright exposure with only a little spray on the leaves once in a while, until spring.
