Bright filtered light is the general requirement, and the higher the humidity of the air the higher light will be tolerated. Outdoors the silvery-leafed varieties can usually be grown in full sun, but in an unshaded greenhouse or close to unshaded glass in a sunny room the same plant will burn because the air dries out the plant quickly. In a very sunny spot indoors they may need daily misting or weekly soaking depending on which method you prefer.
See watering below.
WATERING YOUR AIR PLANTS
Thoroughly wet your Tillandsia 2-3 times per week; more often in a hot, dry environment; less often in a cool, humid one.
The Water you use is important. NEVER USE DISTILLED WATER! Softened Water is not recommended because of the salt content. Filtered water, tap water that has sat long enough for the chlorine to dissipate and bottled water are all fine. Pond water, aquarium, or rain water are all preferred but tap water is better than no water. Outdoors (in the summertime) you may not need to water Tillandsias hanging in a tree if you live in a temperate climate with some humidity. Indoors, the hotter and drier the air, the more you need to water.
Spray misting is insufficient as the sole means of watering but may be beneficial between regular waterings in dry climates to increase the humidity. One last thing about watering your air plant: it is much better to water in the morning than at night. Air plants absorb the Carbon Dioxide from the air at night instead of the day time. If the plant is wet, it does not breath and this can have negative effects on your plant.
