Air plants thrive in warm and humid conditions. Ideally, they should be kept in an environment where the temperature ranges from 60-90°F (15-32°C) and the humidity level is between 50-60%. To achieve this, you can mist your air plant regularly or place it near a humidifier. It is also important to avoid exposing your air plant to extreme temperatures and drafts, as this can cause stress and damage to the plant.
