Hi black_thumb, like Judi says on the same web page there is a link to instructions on how to repot a phal.
I personally keep mine in a bark/leca mixture with a bed of lightly packed sphag near the top. They seem to appreciate it.
With phals you should try to fertilize them "weekly, weakly" that is a bit of food (1/2 or 1/4 strength) every watering with a good fresh water flush once a month to prevent salt build up.
As far as lighting go, they like indirect sunlight, if exposed to direct light the leaves will burn easily.
Other than that they are truly forgiving plants!
Hope this helps!
Phalaenopsis Question
. Some people like moss, others don't. Personally, I never had luck with moss so my phals are happily living in a bark mix. As for cutting the flower stalks, some like to cut it after blooming to give the plant streangth, others leave it because it will probably flower again. Unless my phals look stressed I leave the stalks until they turn brown. I always have new flowers that develop on a stalks that already finished blooming. When it turns brown I cut it just below the point it turned brown if only part of the stem is brown, or as close to the leaves as possible when the whole stem turns brown. As for info with pictures, there is a lot out there on the internet. I like to get supplies from Repotme and they have some good info at
