i don't grow many cycnoches as compare to catasetums. but they share many similarity in terms of their culture. basically just with hold watering during their dormancy, that is when they shed all their leaves. general rule is water in accordance to the leaves, no leaf means minimal water required.
any media with good air circulation is good, but i can plant mine in pure charcoal media (for my local microenvironment here). as for the lighting, use cattleya lighting as comparison.
