This orchid doesn't need much light and should be kept out of direct sunlight at all times, to prevent it from drying out. The humidity of the habitat of Oncidium eurycline should be 80% and slightly higher at night. Water a lot with rainwater or distilled water during its blossoming and less in its period of rest.
