Greenhouse refers to a room with cold proof, heating and light transmission facilities for cultivating thermophilic plants in winter. In the season not suitable for plant growth, it can provide growth period and increase yield. It is mostly used for the cultivation or seedling raising of warm vegetables, flowers, trees and other plants in low-temperature season.

Greenhouse has two characteristics: higher temperature than outdoor, no heat dissipation. The glass flower houses and vegetable greenhouses we can see in life are typical greenhouses. The use of glass or transparent plastic film as a greenhouse allows the sunlight to directly irradiate into the greenhouse and heat the indoor air, while the glass or transparent plastic film can prevent the indoor hot air from emitting outward, so as to keep the indoor temperature higher than the outside, so as to provide conditions conducive to the rapid growth of plants.
