Light: Tillandsia cyanea used as houseplants do best in bright filtered light (a translucent blind is a useful filter). Keep Tillandsia cyanea in a well-ventilated place.
Tillandsia cyanea will grow well, but will not flower if kept in dark.
Water: The negligible roots of Tillandsia cyanea need very little water. If the foliage is most sprayed regularly as advised above, enough water will seep into the mixture.
If possible use rainwater or filtered tap water for misting Tillandsia cyanea. It is generally recommended to water the leaves morning and evening, there would be no problem if they are watered only once a week or even once in 10 days.
Problems: Tillandsia cyanea is generally disease free.
