Phals in sphagnum moss going on bark?

[PhalAddiction]

Bark tends to dry out faster than moss, so you must water more frequently the first few weeks for the roots to get used to the bark.
I always use moss, and switch bark into moss because I love moss.
It is actaully a good medium if you are careful not to over water.
Did you soak the bark before/after repotting? Bark (dried) is not good for phas that are used to moist moss

Also., as bark ages and breaks down it will retain more water and you will water less frequently. Just a side note should you keep trying bark.
