I have seen it growing wild, and probably you have too - all the way round the mainland coast from Mexico round to Venezuela, at sea level ( meaning at all those Spanish Main ports which cruise ships call at - my dear wife used to love our cruises , and I loved the Caribbean sun and heat - nowadays alas she could not walk from one end of a cruise ship to the other, between restaurant and cinema, to save her life...) where it seemed to grow on the sides of the trunk of fair sized trees, surely getting a great deal of light and perfect drainage. But what is different about your conditions ?
But btw, Seeing orchids at sea level is a bit unusual - in the mountains is the usual place.
