Keep air plant terrariums in the bright spot in your house. They love a indirect sunny window sill, and also thrive under bright artificial light, making them ideal accents for your desk at work or school. Outdoors most air plants like indirect light. Air plant roots absorb moisture from the air, therefore they do not need to be kept in soil or water. Spray water on the air plants to induce moisture on roots, once every day and less in more humid areas. Most air plants are pretty slow growing, so you typically don't need to worry about pruning them. Just remove the leaves that have turned brown. Air plants thrive with good air circulation, but do not keep directly under a fan/AC. Note: While they're beautiful and easy-care plants, air plants are not intended for human or animal consumption.
