Chunky old Den Phal thriving in ... gravel?!?

[Fairorchids]

Orchids can be grown in (almost) anything, as long as you adjust your watering & fertizing schedule accordingly.

I recently received some Laelia anceps from Santa Barbara Orchid Estate, which were in plastic pots with all rocks (1"-1.1/2" size). They were doing fine, but to fit in with the rest of my collection, they are now in clay pots with a bark/charcoal mix. And, they are growing fine this spring.
