Hi Jim! I have a couple of Paph.'s in s/h. This is my experience. You should really wait for new root growth before switching an orchid to s/h culture. I got lucky....I didn't learn this rule until after I put two of my paph's into s/h. One took right to it and is doing great. It has a second growth that is now taller then the original growth. The second one I haven't really seen any growth on, but I thought I saw signs of new roots growing closer to the surface, it is hard to tell without taking it out of the s/h medium. I still have several paph's in bark medium....I think I will eventually switch them all over to s/h when the timing is right with new root growth. Hope this helps! Oh...and I don't do anything special for them. I treat them like every other orchid in s/h medium.
