black gold orchid bark.mix?

[kindrag23]

Two of my knew catasetum/cycnode/clowesia orchids came in a bark mix media instead of sphagnum moss like my others. I emailed one of the sellers and she said she makes her own up. But she had many people who use black gold orchid potting/bark mix. I have never heard of this...I found it online and they have good reviews but all I am finding is fine bark mix...would that be okay for my catasetums? Because if they are happy in bark I want to keep them in bark..

Thanks!
