from what i read, it might be bacterial.

al keeps his phals in pea gravel--but he has a GH where he can control
the humidity. this morning, for instance, the orchids were in 50%
humidity acc to the hygrometer.

thx for the suggestions; i will keep griping to myself and yelling at
the plants and maybe just try spraying things on 'em til they die.
