Light:

Partial sun, an eastern or western exposure. Some direct sunlight is beneficial.

A minimum nighttime temperature above 50° with a 10-degree increase in temperature during the day is helpful.

Humidity:

Preferably 50% or higher; put orchids on a humidity tray or a tray with pebbles to help with humidity.
