Glass terrariums are small, enclosed environments made of glass that house plants, soil, and sometimes decorative elements. They create a mini-ecosystem where plants can thrive, often requiring minimal maintenance. These containers can vary in size and shape, from simple jars to elaborate designs, making them popular for home decor. Inside a glass terrarium, plants like succulents or ferns can grow, benefiting from the humidity created by the enclosed space. They are often placed on tables or shelves, adding a touch of nature to indoor settings. Proper care includes occasional watering and ensuring adequate light for the plants.
