Dendrobiums' light needs vary during different stages of growth. The growth period occurs after flowering, usually during spring through summer. During periods of growth, strong light is necessary.

Light should be adjusted to provide 20-35% of full sun. If you have a light meter, it should read from 2,000 to 3,000 F.C. (foot candles).  If a meter is unavailable, you can judge the amount of light by touching the leaves to see how warm the feel. The leaves should feel warm but not hot.

Less light is necessary during periods of rest or slow growth, usually from fall to winter, after blooming has occurred. Light should be adjusted to provide 15-25% full sun. If you have a light meter, it should read from 1,500 to 2,500 F.C.

Over time, leaf color is a good indication of whether or not the plant is receiving the proper amount of light. Leaves should be medium green for the plant to bloom.
