I think superbiens is a Laelia and Schomburgkias do not exist anymore. They are either Myrmecophila or Laelia.

I have a Laelia superbiens alba. It can take full sun on the roof with no leaf spotting. No blooms yet. in a clay pot with chunky lava rock used for grilling. It is producing fat pseudobulbs and roots. I saw a lot of Myrmecophylas during a recent trip in Quintana Roo state in Mexico. They use them for landscaping. I think full sun there is too much if they are not in the jungle. Some they looked baked. But there was a lot of breeze for the ocean and that may dry the roots and leaves up too much. I was surprised to see some very happy ones in a Mangrove swamp. The plant were totally shaded by the red Mangrove branches and the spikes were long and above the canopy.
I tried to attach some images to show how they grow in the wild but I was not allow as my files were 900 pixel wide and there is a 700 pixel limit.

Anyway potted with coarse media seems good
