These are entirely natural in a rainforest at 1500m altitude.

Rain water in asia, in a similar fashion to rainwater in south america, contains weak fertiliser. In the case of south america its picked up from a dry lake bed in the sahara desert and carried over to south america, (actually southern spain also recieves a good amount of nutrients from the same source). For far east asia its picked from the gobi desert.
If the long forgotten Sahara monsoon ever re-starts, brazil might find itself with a less fertile forest.

I've allways found this phaelenopsis interesting from a fertilizer point of view, its growing in a temporary river bed and regularly submerged. (daily in the wet season). So any fertilization is essentially from rain water and nothing else.
Just to show its not a fluke, most of this species grow like that,
