cyp arietinum culture

[cmu]

Hello,
I bought a small flask of cyp arietinum from Robert's Flower Supply at our orchid society show last fall. He told me to deflask for the winter and put the seedlings in barely damp sphagnum, in a jar and refrigerate for at least three months over the winter. I have done this, but I need to know if anyone has culture for growing ram's head in pots? I need most to know what kind of media to use for this plant. I've seen it growing in low pine duff, where the trees are growing over limestone. So, some directions i've seen said grow acidic, others say neutral others calcareous. Where they grow in ny, it's in the mossy hummocks over calcareous stuff. So information is confusing at best! I had read one thing on an orchid wiki that said the soil pH should be around 6.

any help would be greatly appreciated!
