A terrarium is like an aquarium, but for plants instead of fish.
It is planted to look like a miniature garden or forest enclosed in its own little world.
You can easily make a beautiful terrarium yourself.
Terrariums are most useful for small plants that do not adapt well to normal home atmospheres.
When properly planted and located, they provide a novel way to grow many plants with minimal care.
A terrarium is a good way to keep plants indoors with a minimum of care.
