A terrarium is a miniature garden enclosed in a clear container, often made of glass. It creates a self-sustaining ecosystem where plants can thrive with minimal care. Inside, you can find various plants, soil, and decorative elements like rocks or figurines. Terrariums can be open or closed, depending on the humidity and plant types you choose. These tiny gardens are not only beautiful but also educational. They demonstrate how photosynthesis works and how ecosystems function. Creating a terrarium can be a fun project for kids and adults alike, allowing you to connect with nature indoors while adding a touch of greenery to your space.
