vermiculite
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.

vermiculite
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. --j_a In article , "Diana Kulaga" wrote: Well, that's not particularly good news, now is it?

vermiculite
If you want to look at details, ALL media components are a risk, to some
extent. Perlite is almost 100% silica, which can cause silicosis. Same is true of diatomite. Be smart in how you handle it and all will be well. I worked with uranium- and thorium oxides in college, both toxic as hell, but I'm still here to talk about it - because I took relevant and appropriate precautions. Hell, trichosporosis - a fungal infection from sphagnum - is a bigger threat. (And no, my recent "episode" with melanoma was not related to any of the above) -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies. Books, Artwork, and lots of Free Info!

Sage advice, Ray. That's why I *always* wear gloves, and change them often.
I wish I could convince Frank to do the same. Diana "Ray B" wrote in message news:R4NUj.369$be.256@trndny02... If you want to look at details, ALL media components are a risk, to some extent.
