What is the primary purpose of a greenhouse?

The primary purpose of a greenhouse is to provide a controlled environment for the cultivation of plants. This controlled setting allows for optimal conditions such as temperature, humidity, light, and soil moisture, which are essential for plant growth and development. By manipulating these factors, greenhouse growers can extend the growing season, improve plant health, and increase yields compared to outdoor cultivation where environmental conditions can be unpredictable.

While storing gardening tools and materials, protecting wildlife, and growing plants solely for decoration are all valid activities associated with gardening and horticulture, they do not represent the primary function of a greenhouse. The core intent of a greenhouse is focused on enhancing the growth of plants by creating conditions that mimic or improve upon their natural habitats.
