As a rule most Vandas prefer a slat wooden basket with not much medium over the roots and steady water, fertilizer and humidity year round. Most all Vandas appreciate direct sunlight at some time during the day and some can tolerate full sun all day. Generally a plant with more terete [tubular] leaves likes more direct sunlight than a Vanda that is strap leafed or has a "V" shape in cross-section.
