I bought a Haraella retrocalla recently. I'm having a little trouble finding care information for it. It's my first orchid. I've done tons of forum reading on orchids in general, I just can seem to find anything specific on this orchid. It's potted right now, but I plan to mount it after I get paid next week. How often do I need to water it? I've read to let it dry out a little and I've also read to keep it wet.
