Well, the Dendrobium tetragonum is one I grow. And I managed to bloom it a couple times so far. Mine is in a tiny pot, I have seen others mounted on tree fern placques. Mine wasn't doing too great so I sat the tiny pot into a larger pot that contains a couple epidendrum sections. Both get sat on shelves close to the Vanda section so they get watered a little more often, lots of sun and high humidity. Hope that helps...
