I came across a pretty good Youtube video on potting mix. The quick summary is to use sphagnum moss on the bottom with a little sphagnum connecting to the middle of the potting mix. Then use bark or bark and perlite for the rest. He uses a net pot. Using this mix in his experiment so far has yielded really good results. In his climate, he waters every 4 to 6 days and hasn't experienced any root rot.
If you feel like experimenting, I think this is a good technique.
