Kemistry,
Orchids 3 is ABSOLUTELY RIGHT in asking where you live (Climate zone) so as to determine what your ambient climate conditions will be.
I always wonder however, why novice growers want to start with a species of any kind.
Species of any genera are far more demanding in their needs than hybrids and as as a result, most often die from a well intentioned grower but the wrong cultural conditions. I have grown Cymbidium species for over 45 years and I have never had true success with any of the Asian species, not because of potting mix but because of climate. They survive for a few years but eventually fade away.
I do not want to discourage you, but I would Google every resource on a specific species and read every book I could find. Locate and talk with growers who are EXPERIENCED in successfully growing the species. Only then should you venture into another species which otherwise may cause you nothing but heartache and for which you may not have the correct conditions. Potting mix is only the beginning!
