CARING FOR YOUR AIR PLANTS
Air plants should be kept where they'll receive bright, indirect sunlight or under fluorescent home/office lighting. Periods of direct sunlight are just fine, but more than a few hours of hot sun will deplete the plants of their moisture. If your plant will be in a spot with some pretty direct light, try misting them every couple of days to keep them hydrate.
Best way to water your air plants is giving them a thorough rinsing under running water or letting them soak in a bowl of water for 20-30 minutes. After their shower or bath, gently shake the plants to remove any excess water from the base and the leaves, and set out to dry in an area with enough air circulation to dry them out in about 4 hours. If your plants need an in-between watering, misting them with a spray bottle is a great method. A plant in bloom should be rinsed rather than submerged in water, and take care when rinsing the delicate flowers.
HOW OFTEN DO I WATER MY AIR PLANTS?
Your plants should be watered once per week, and 2-3 times is recommended for optimal care. A longer, 2-hour soak is recommended every 2-3 weeks. If you are in a drier, hotter climate, more frequent watering or misting will be needed. You'll begin to notice that after watering, your plant's leaves will feel stiffer and full of water and they'll be softer and lighter in color when they're in need of water. Wrinkled or rolled leaves can be a sign of dehydration.
Air plants will do best in generally warm conditions (a good range is 50-90 degrees).
