the reason asking for the colour of the leaves, is because I thought you were in Maracaibo and therefore spotted leaves would do better under those conditions...
here you can find good info for Paph cultivation:

but as I said, let those in the states give you better tipps, especially regarding which culture medium you should use or easily find in the USA.
(I can only suggest S/H - semihydro- wich works perfect for my Paphs...)
