Promote root growth for baby Phals

[clusty]

Hey,

I got a small baby phal pure blue violacea with 2-3 1" rootlets and a bunch of dead roots. It was planted into pure moss. Since i have bad experience with it i repotted into fine bark and sprinkled just a little moss in the mix. I planted this in a plastic net orchid pot.

Is there something I can do to stimulate the root growth ?
What about the watering schedule? Do I make sure the top part of the mix is constantly moist ? (2 mists a day)
