Vandas and Spanish Moss

[LILOBODO]

I have six vandas growing in slatted baskets hanging in our east facing lanai here in Venice, Florida, s.w. coast. My wife drapped some live Spanish moss over the baskets a couple of years ago and the baskets are pretty well covered although many roots show through. The vandas seem to be doing well, but I wonder if the moss may be holding too much moisture?
The vandas get about eight hours of sun through the screen lanai and are watered four or five times a week.

Thanks for any comments
