an interesting thought.

hey.. i found this question very interresting so i wrote a proffesor i used to have about it, since his main field of interrest are orchids. i explained to him (forgot to send pictures though). his answer was that it most likely sounded like physical damage or to much watering that can make the leaves to "crisp"

if its new leaves on plants that isnt moved around then i guess it happens from to much watering, since im sure very few abuse their orchids

I don't buy the "too much watering" scenario, as all of my phals are in semi-hydro culture - with an unlimited water supply - and I have not seen such splitting in a long time.

My question is not how you get higher than 99% but how do you get 99%. During the recent tropical storm, my greenhouse stayed at about 85% humidity for about five days and it smelled like a funky cellar from all of the mold and mildew, even though I had lots of fans running. It seems to me that humidity in the 90's would just be a breeding ground for bacteria and fungus.

My reference to 99% was for Angraecoids, that do same thing sometimes. They all grow fine in a "tank" (an orchidarium, with misting and closed environment but constant air movement from DC fans.) Yes rot and mold is a constant battle, but certain plants demand this environment, and I choose gladly to provide it Sorry it was not for Phals, the subject here, but I had made a point, I think.
