Give your tectorum plants a thorough misting every 1-3 weeks depending on your climate. Water with less frequency in humid or damp climates, and more in dry ones. Remove them from an enclosed globe or terrarium for misting, waiting for them to fully dry before displaying them in enclosures again. The plants should be completely dry within an hour of watering. The tectorum's white appearance reflects a good amount of incoming solar radiation. Because of this, they require bright light to properly photosynthesize. They will do well in window settings. In low light conditions, they will likely not deteriorate but essentially cease all growth, which is a snail's pace even in optimal conditions.
