Cyp. Orchids In SoCal ( temperate type)

Have you heard of Botany Boy and come across his blog? He lives in southern
Japan and has shared his experience growing hardy cyps in his climate.
He does talk about the double pot technique for cooling roots. Here is a
a post of his re: Cyp. Kentuckiense.

I think in general, cyps, calanthes and other terrestrial orchids will do
better if grown very lean. No humus, no earth. Just a mix of gravel,
charcoal, pumice and the like.

Keep us posted on how you get on.
