How to create and care for a terrarium

Terrariums are closed transparent glass or plastic containers used to create a mini-environment or ecosystem for plants.  The principle behind a terrarium is simple. The water from the soil is taken up into the plant as it grows. The water is then released through the leaves via transpiration. This water condenses on the glass and runs back to the soil, where it can be used again.

Because this mini water cycle occurs inside the sealed terrarium, the plants can go for months without watering. It also creates a jungle-like atmosphere of high humidity, warm temperatures, and no drafts, which are perfect conditions for many of the tropical-native houseplants common in homes.
