Your Terrarium needs bright indirect light. If you place it outside be sure it is on a covered patio out of direct sun. Succulents do well with Eastern morning light. Water when soil becomes dry. Every two - three weeks is advised.
Tillandsias are some of the most unique and fascinating members of the Bromeliad family. Commonly referred to as "air plants" they derive all their moisture and nutrient from the free moving air around them. If your Tillandsia creation is mounted on wood or rock, mist with a spray bottle every other day for many years of enjoyment.
The Hanging Globes dry out somewhat faster than a larger table-top Terrarium. The smaller size should be watered once a week and larger sizes every other week.
Our Geometric Terrariums contain Tillandsias. They need to be removed from the container and misted twice a week.
It is always better to under-water your succulent creations than over-water. Always water thoroughly when watering.
