Hi Sandy
I repotted my phals in wire baskets filled with rocks a few months ago. i grow all my orchids outdoors and during raining season they got overwatered. I had them in pinebark, charcoal and coconut husk before. Since the switch they're doing very well. I do need to water them everyday during the dry season but hey better than having them die when it rains everyday...
After seeing pix of the mounted phals I think i'll try that too...
