Growing crops whatever the weather: automated weather protection for growers

Source: Cravo Equipment Ltd

This economically sustainable production system creates optimum growing conditions by managing adverse weather conditions. It uses a motorised roof system that can close hectares of roofing in minutes, with one motor per hectare of roofing. The system is controlled by a weather station that monitors temperature, rain, wind and barometric pressure to protect crops from hail, extreme hail, wind or cold. Protecting crops from extreme weather can increase yields threefold and allow crops to be produced virtually year round, even in extremely hot locations. In addition, the cooling properties of the roof covering can reduce water usage by 50% and cut losses due to insects and disease. The roof covering has been developed to have a useful life of 8 to 12 years even in locations with high radiation.
