Air Plants are clever little creatures and need nothing to live but air and water. They can even handle low light areas! They love a spot like a bathroom which has high humidity, but where ever you keep them they generally still need your help to hydrate. Spray with water every few weeks or take them out of the container and run water over them, shake them off before returning to the container. If they are looking very dehydrated and every few months you can soak them for an hour to overnight (preferably in rain water).
