Can Tillandsias be kept indoors?
Tillandsias need bright filtered sunlight to grow well. When kept indoors, they should be placed as near the window as possible. If that is not possible, use artificial light (florescent light, ‘daylight’ bulbs) to shine on them for 8-14 hours a day, its best to place the light between 15cm – 30cm away from the plants. If artificial light is not an option and you would still like to display your plant indoors, plant rotation is the answer. Get 3 specimens and rotate them once every 2-3 weeks. That means, display one plant indoor, the other 2 should be placed near the window where they get sunlight to make food and grow. After 2-3 weeks, move the plant indoor out near the window and replace it with another plant.
