What is the primary purpose of a greenhouse?

The primary purpose of a greenhouse is to provide a controlled environment for growing plants. This controlled environment allows for the regulation of temperature, humidity, light levels, and other factors, which are essential for optimal plant growth. By utilizing materials like glass or plastic, a greenhouse captures sunlight and retains heat, creating an ideal setting for a variety of plants, regardless of external weather conditions.

Controlling the environment also enables growers to extend the growing season, cultivate plants that might not thrive in the local climate, and protect plants from pests and diseases. This focused approach aligns with the objectives of commercial horticulture and hobby gardening alike, making greenhouses critical in achieving higher yields and healthier plants.
