chipped terracotta for phalaenopsis?

[james mickelso]

I have used lava rock (same innert dryness as terracotta) for phals with very good success. Here are a couple pics. If I use moss I pot the phal loosely so that the roots dry out in short order. In bark I use charcol and sponge rock with it and use a medium mix. In lava I use a medium coarse grade. I like a very airy mix because I would rather water more often and therefore feed more often than have to guess when the center of the mix under the roots is dry enough to water again.
