so it won't hurt the plants to spray w/ 1 % bleach?

Fungus has more to do with the condition of the plant and the temperatures
than the S/H culture technique itself. Treat with a fungicide (1% bleach
works well) and try growing a bit warmer.

I assume you're using PrimeAgra? I have two fans that provide air
movement
in my growing area. They're not directly trained on the plants but
about
three feet above them. This, plus the ambient humidity, keeps the top
layer
and perhaps an inch to an inch and a half of substrate dry. If you're
having problems with mold or fungus, it's more than likely moisture
related
and just lightly spraying the top layer with Daconil will take care of
the
problem temporarily; but it will be interesting to get Ray's take on
this,
and what he'd suggest. He's been at it a lot longer than I have.

I have considered adding 1/2 teaspoon of Physan 20/gallon on a monthly
basis for algae or fungus, but I'd check with Ray at Firstrays.com and
see what he thinks. They have an excellent discussion forum on the
site.

fungus on the roots through the transparent pots.

What am I doing wrong? How do I get rid of the fungi before it kills
off my orchids?
