It's been six months and still don't know what this is

Hey guys i took it completely out of its medium and left it like that for a week, not watering it often, having the fan blowing gently and no fuzzy stuff growing on it at all. It only grows when it was in medium. only 3 roots left.
I've been doing research and heard of using a little bit of rooting hormone on orchids, people had success with it.
So what i did i sprinkled the base with the hormone and wrapped the roots with a just slightly damp paper towel and i covered with a plastic bag (i know you're only supposed to do that with no root orchids) but giving it a try anyway. I did this last week so i want to wait about a week or so and see what happened.
