Greenhouses, also known as hothouses. Structures that allow light transmission and insulation (or heating), used for cultivating plants. During seasons unsuitable for plant growth, they provide a controlled environment for plant growth and increase yields, commonly used for the cultivation or seedling of warm-weather vegetables, flowers, trees, and other plants. There are many types of greenhouses, which can be further categorized based on different framing materials, lighting materials, shapes, and heating conditions.

Greenhouse types include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental greenhouses, catering greenhouses, recreational greenhouses, and more; greenhouse system designs include heating systems, insulation systems, cooling systems, ventilation systems, control systems, and irrigation systems; hoop houses are merely simple plastic film and skeletal structures with minimal interior facilities and do not meet the high standards of greenhouses. Therefore, strictly speaking, greenhouses have higher equipment requirements and may necessitate more advanced instruments for precise temperature control.
