OK, we'll pull it out of the pot as the blooms are about done now anyway and just use gravel, lava rock and coconut chips. I may put some coconut coir around it so it doesn't have to be watered every day. I've discovered that I have to water my bare root orchids too much for it to be practical in this heat so I've got them on a tree but wrapped with some coconut coir and some coconut chips inside so it holds a little moisture. I don't often get blooms on some of them, the vandas, and I'm guessing that is because they need fertilizer. I'm going to work on getting that sorted.
