Here is what Orchidwiz had to say: Pot in large container with medium bark, some chunks of pearlite, or chunks of sphag to hold a small amount of moisture for the roots. Media needs to be fast draining.Light should be bright filterd or diffused, protect from direct mid-day sun. Needs constant air movement. Temps Summer- day26 C nights 18C winter-days21C, nights 11 C. Does better potted when grown in warm conditions. Keep nearly dry during 2 to 3 month winter rest. In wild, plants survive with dew. No fertilizer until spring watering begins. Winter humidity about 65, summer humidity aroud 70%.
That should help quite a bit. I'm glad I got that orchid program when Orchidtalk members could get it with a discount.
