Terrarium
> Terrarium is a container which is designed to hold small plants in controlled conditions. The closed nature of a terrarium creates an environment which is easy to control, allowing people to stimulate everything from the desert to the rain-forest
> Terrariums can be purchased from companies which specialize in them, and they can also be made by hand; people who want especially large or custom-fitted terrariums often end up making their own.

> Typically, the container is clear, allowing an unobstructed view of the contents, although a terrarium can also be built from wood and other materials with sliding panels to allow a view.
