Agriculture on the rooftop for self-sufficiency and saving water (2)

Ragab Rabei, a citizen who invented an agricultural system based on growing grains and seeds in plastic pipes on the roofs of his house that is located in a very small village called "Kafr Un", in Ashmoun district of the Menofia Governorate, in the Arab Republic of Egypt. The main concept of this idea is to save water, where only 50 liters can be used to cultivate an area of half an acre, and therefore, Ragab has circulated this idea to the entire village.
