Te primary reason to repot when using organic media is to rid yourself of
decomposing material, which packs easily and traps lots of water in the
"macropores" between the media particles, both of which combine to reduce
air flow to the root system, setting you up for root rot.

A decent ceramic medium will exhibit none of those symptoms, so the repot is
neither essential, nor advisable.

I have been growing my dendrobiums in expanded clay balls for quite some
time now with fair results. I am wondering if I should keep some kind of
repotting schedule, as I do in more conventional media, because there is
no breakdown in the clay. I do change the water occasionly of course.
Please give me your experiences.
