Psychopsis are generally one of the easier orchids to grow. The hybrids are much more sturdy than the species.
They like water and mine are grown in Sphag unless my supplier ships in a bark sphag mix.
They do not like re-potting and I leave mine in the original pots for many years.
Of the 500 or so I have owned over the past years I do not think I have lost more than about 20
