The plant is about 25cm of diameter (similar to a ball)
Water for Tillandsia:
Thoroughly wet your Tillandsia 2-3 times per week; more often in a hot, dry environment; less often in a cool, humid one. In conditions of extreme drying, and consequent moisture loss, Tillandsia cannot get replacement water from their roots like a terrestrial plant, or draw on internal reserves like a succulent.
Spray misting is insufficient as the sole means of watering but may be beneficial between regular waterings in dry climates to increase the humidity.
Tillandsias will not survive in standing water. Under-watering is evidenced by an exaggerating of the natural concave curve of each leaf. After wetting your plants thoroughly, turn them upside down and gently shake them. I have found that the water that collects near the base is detrimental if left to long. I have lost many plants that way while learning. One last thing about watering your air plant – It is much better to water in the morning than at night.
