[0002] A seedling greenhouse, also known as a hothouse, is light-transmitting and heat-insulating. It is a facility used to cultivate plants. In seasons that are not suitable for plant growth, it can provide a greenhouse growth period and increase yields. It is mostly used for the cultivation or seedling raising of warmth-loving vegetables, flowers, trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof materials, lighting materials, shapes and heating conditions. The types of greenhouses include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental greenhouses, catering greenhouses, entertainment greenhouses, etc. The design of the greenhouse system includes heating system, insulation system, cooling system, ventilation system, control system, irrigation system, etc.
