Why is agriculture in the GreenTower more profitable than in standard greenhouses?
One reason is that in desert areas standard hothouses use huge amounts of costly sprayed water to keep plants cool. The GreenTower’s hothouse is air cooled at no cost. Drip irrigation with collapsible, removable piping allows the use of machines contrary to other hothouses and ensures the lowest possible production cost as also the most efficient use of vegetation-evaporated water, which is re-condensed during night and early morning hours. Humus in the greenhouse soil (volume content between 12% and 25%) ensures a root growth of up to 1m in three days, exceptionally high yields and a low cost organic agriculture with 30% higher prices through automatic nitrogen generation by microbial assimilation in humus soil at no cost. Due to antibiotic bacteria in humus no pesticides etc. are required.
