Evangeline,
I will repot these plants in medium bark compost. Personnaly, I do add some pieces of polysterene at the bottom at the pot. My phals do pretty well that way. I would as well put some sphag at the top of the pot initially until I get few new roots, but then I do live in a flat where humidity is pretty much difficult to control. In any case, it will take time: Patience is a vertue
Good luck
