I have 2 S. cernua, having killed the first one I got. These are mounted on cork, outdoors in coastal SoCal, and I spray them every morning with very dilute fertilizer. They seem to be doing better than the departed one (setting a low bar here). I keep the bark horizontal to retain moisture. I haven't flowered them yet. A companion S. rosea is doing much better with the same regimen.
You are probably aware of the AOS article on S. culture, (
The Culture of Brazilian Sophronitis ) but it deals exclusively with S. coccinea. Cernua is supposed to tolerate more heat than coccinea. Good luck.
