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 hydrated.
While air plants don't grow in soil, they definitely NEED to be watered. While the plants can survive for long periods of drought, they will not grow or thrive and will eventually die off if water is too scarce.
Airplants like humidity and do best when spritzed several times a week with water. Do not let them sit in water. Airplants enjoy being fertilzed with a good airplant fertilzer once a month.
