Your favorite mix for watering loving Phrags?

[bethmarie]

I have Phrags in need of new medium and I'd like to hear what other growers prefer for water-loving species and hybrids. Most of mine are in medium bark mixes currently, and it takes very frequent waterings to keep them happy. I'm trying to make them at least marginally lower maintenance with a more water-retaining mix.

If you love your Phrag medium recipe and want to share,
I can't wait to hear it!
