What is the best planting medium / mix for Orchids?

[johnteller8]

Greetings:
I have been an orchid enthusiast for about 10 years. My late Aunt had an excellent collection of all kinds of Orchids, and after she passed a couple years back, I decided to start growing orchids on my own in her loving memory.

Question i now have for you folks is this;
What is the best planting medium / planting mix for orchids?
Rather than mix my own, I am looking for a complete mix that I can simply purchase. My Aunt used to get "Buckhead Orchid Mix", but i can not seem to find it or get any information. Has anyone heard of "Buckhead Orchid Mix", or can anyone reccomend a complete orchid planting medium?

thanks in advance.
