Overwhelmed with Potting Media Options

[drmoonshine]

Aloha,

We live in Hilo, Hawaii at about 750-foot elevation. It rains nearly every day and temperatures range from 65-90 degrees.

We are fairly new to orchid growing but already have a small collection of Cattleya, Phalaenopsis, Dendrobium, Laelia, Slipper, and Vanda orchids.

Several are blooming now and I thought I would repot them when the flowers are gone. I am overwhelmed with all the potting media options and don't know which one(s) to chose.
