Hot weather, to bare root or not to bare root?

[Charles]

I have been having a difficult time deciding whether or not to "break the rules" concerning vandas and potting medium.
I live in a dry hot area and the summers here are brutal. The humidity is not always high enough for the heat.
Do I leave Vandas bare or not? I have some already in medium and I just purchased two well established bare plants. What to do?
I realize the possible drawbacks, if not outright dangers of using medium and over watering, but the heat and dry is no small concern either.
Everyone says no to using medium for Vandas. What are some thoughts here?
