Moss and bark layering question

[KE8ICR]

I have been trying to save a NOID Phal I got at a grocery store. It was blooming when I bought it, but it was potted in a thin plastic "cup" with no holes, and spagnum moss packed very tightly around the roots.I noticed it was starting to get root rot so I decided to repot it. The leaves were and still are limp. When I repotted (remember I am a newbie) I removed all the old moss, and cut all the dead roots. I put it in a willow basket with more spagnum moss but loosely. This didn't help and in fact the root rot got worse. I decided to watch some videos on You Tube to get some idea of what I should do next. After watching one of the videos, I started a routine for about 5 days of soaking the roots in diluted tea water with a minute amount of rooting hormone all day and pulling it out to dry all night, and repeated this process for 5 days. Well you'd think Ol green thumbs here would have killed it off completely by now, but what few roots that are left plumped up and got greener and that gave me hope. While the leaves are still limp, the roots have improved some so I decided it's time to put it. This time I bought some bark. I got the (brilliant LOL) idea that if I put some moss in the bottom of the pot, put the bark on top of that, then put in the orchid so none of the roots came in contact with the moss, the humidity might stay higher without causing root rot. Please advise on the wisdom of this decision. Thanks
