Air Roots Shriveling

[josterha]

Hello,

I have about twenty Phals in my collection. I have noticed lately that I am getting good strong roots that develop either just above the potting medium or out of one of the side holes in an "orchid pot". These roots look strong and thick and green. After a few weeks, they usually turn gray and then eventually shrivel up. Am I doing something wrong? The RH is always above 50% and closer to 60% usually. I am underwatering? Should I try to cover these roots up with sphag? Please help.

Thanks,

John
