i remembered that either vermiculite or perlite was a problem, but i
couldn't remember which.

are there problems with perlite?

oh, and potting soil can give you legionnaire's disease.

Well, that's not particularly good news, now is it? Vermiculite is in most
potting mixes for those *other* plants. Wonder if it's in some of the
commercially mixed orchid stuff?

For my part, I mix my own orchid media, so it's not an issue unless we're
working on other potted plants, which is not common.
