Crops and green vegetation require water for the entire process of germination and growth, involving photosynthesis. However, over 99% of the water consumed by plants is used for transpiration from leaves and soil evaporation between plants, to regulate crop temperature, improve microclimate, and transport nutrients within the plant. Without adequate water supply, the growth and development of crops will be inhibited and damaged.The emergence of greenhouses aims to change the passive dependence on natural conditions and actively influence and control crop growth.
