Greenhouses utilize the "greenhouse effect" to create a suitable environment for crop growth by regulating indoor temperature during seasons when crops are not suitable for outdoor growth, in order to achieve crop production and increase crop yields. But with the advancement of science and technology, greenhouse production has far exceeded the concept of "greenhouse effect". At present, high-tech technology can be used to automatically control and adjust various environmental factors in the greenhouse, including temperature, light, humidity, carbon dioxide concentration, etc. According to the growth habits of crops and market needs, some or even completely break free from the constraints of the natural environment, artificially create a suitable environment for crop growth, and produce high-quality and high-yield products to meet the needs of different consumer groups.
