i've been considering s. japonica myself. from what i understand, they grow well like a phaleanopsis? but can handle more cool weather. when i finally get one, i will put mine into a tree-fern pot, with some moss and fern fiber. it has no bulbs, so it might need a bit more moisture, and where i live it is very dry, so i will use moss int he mix. using a treefern pot is sort of a cross between potting and mounting. i've only seen them mounted on the internet, never seen one in a regular pot, so mounting is probably well tested.
