It's care is that of any Phal, really. Dappled light, fertilize weekly weakly, water when the medium is JUST dry. In so far as medium, I prefer a bark mix but it really depends on how you grow.
I keep all the species Phals (including the 5 or 6 equestris already here) either mounted or in baskets hung sideways. They are just outside of the bright Cattleya light (about 8 inches outside of where the Catt section ends on that shelf), the roots get misted everyday and I fertilize once a week during summer and once every two weeks in winter, just like everything else here
