A greenhouse is a special building made of glass or clear plastic that helps plants grow by trapping sunlight and warmth inside. This controlled environment allows gardeners to grow flowers, vegetables, and fruits all year round, even in cold weather. By using a greenhouse, plants can thrive without the threat of harsh weather conditions like frost or heavy rain. Inside a greenhouse, you can find various tools and equipment, such as pots, soil, and watering systems, to help care for the plants. Many people enjoy gardening in greenhouses because it allows them to experiment with different types of plants and create a beautiful space filled with greenery.
