Air plants are an interesting plant. It thrives on the oxygen in the air, but a common misconception is that air is the only thing they need. They also need water and light. They come in a variety of shapes, sizes, colors, and displays. They can be displayed in shells, glued to rocks or bark, and many more.
Light: Air plants love bright indirect light, but not direct light.
Water: There are many different ways to "water" your air plants. Every 1-2 weeks you can give your air plants an "air bath". This involves soaking your air plants in water for about 5-10 minutes. You can also mist your air plants frequently. These plants enjoy a moderate amount of humidity.
