ABSTRACT:
A method and system for purification of water for plants in a greenhouse structure. The method comprises condensing water vapor in the air in the greenhouse on the greenhouse walls, collecting the condensed water at the base of the walls and passing the collected water to the roots of the plants. To accomplish this method the system comprises a water supply for water to be purified, a mist generator for the air in the greenhouse from the water supply means and a heat source to generate heat in the greenhouse for vaporization of the mist. Cooling means are provided for the walls to cause water vapor in the air in the greenhouse to condense on the interior surfaces of the walls. The condensed water is collected and carried by conduit means to a nutrient solution reservoir for admixture with nutrient to be supplied to the roots of the plant.
