Traci, several people have reported that plants newly potted in sphag have experienced "revitalizing effects" if they have suffered some root loss, and, for a limited length of time, fresh sphag does provide some fungicidal benefits. But this is all short term-- a period of a couple months. And, if you're not careful watering, there won't be any revitalizing effects at all.
Your Phal's inner roots were wrapped in sphag because that's what the growers put the seedling in when they transfered it out from flask. When they repotted after it grew some, they just stuck the seedling "plug" inside a pot with mix. Happens all the time; it's pretty common practice actually.
If you want to keep it in the sphag you've just potted in, absolutely positively MAKE SURE that you only water when the sphag around the root zone is just barely barely damp.
I decided to put it in bark. This is why I don't grow phals, they are so sensitive lol! I better stick to my difficult to grow orchids that I do just fine with.
