Hi Ray

Thanks for the advice. But no, I was aware of crown rot and I'm always
careful about not getting water in there. I lost my first phal to crown
rot, but since then I have learned my lesson and haven't had any more
problems. I just mist the aerial roots sticking out of the pot, the
other roots that are in the mix are usually never dried out.

Cheers,
Xi

If your plants are THAT dry after a day, then you're not watering well
enough and/or your environment is too dry. Misting the roots alone does not
add all that much of a fungal threat. It's the crown I was concerned about.
