Farmers and investors need to know what level of technology they should apply in order to have a feasible
production facility. At Estidamah, three levels of technology are present and have been studied. A pad and fan
tunnel greenhouse with an advanced water and nutrient supply system is considered as the standard technology,
implemented at most of the farms in KSA.
A multi span greenhouse with a glass covering is considered as Mid Tech
technology. The most advanced system is the closed greenhouse, where the air is conditioned by chillers. All
three levels of technology have been evaluated in terms of resources usage
