actually, a photo of the medium it is in now may help us help you... i don't have this one myself, but i have a bollopetalum, another hybrid in this family of orchids. it does not like to dry out, and can handle pretty high light. i would use a very small plastic or slightly larger clay pot of sphagnum moss, and maybe mix in a bit of treefern fiber to keep it looser. but it is very dry here, so you might not need to use so much moss if it is very humid there... i have seen photos of people growing this in semi-hydro, so i assume it also does not like to dry out. i keep my bollopetalum moist year round, outdoors in very bright shade. i accidentally let it dry out to much in the summer heat this year and it lost a lot of leaves. but i brought it back from the brink of death once before, they seem hard to kill and quick to recover once happy again. good luck! the one you picked is a beautiful plant.
