This is probably best considered an intermediate grower that tolerates winter cold when kept dry but may be stressed by summer heat. The closely related Prosthchea/Euchile citrina and karwinskii are definitely cool growers and that may influence how people think of this species. If you can give it high humidity and grow it mounted, moist in summer but rather dry in winter, and avoid stressing it with summer heat, it can be problem-free. Easy in a greenhouse, more difficult indoors. If winter conditions indoors are warm it is harder to keep it dry enough at the roots without drying out the plant too much, and if humidity is low spider mites will often be a killer. What is easy often depends on what conditions you can give.
