Conventional hydroponic systems require substantial amounts of energy to keep the nutrient solution in circulation.  Root hairs are sensitive to the  oxygen in solution.  Since this oxygen is delivered by the nutrient solution, pumps are maintained running 24 hours per day to supply this demand.

Sol-Aeroponics is a cousin of hydroponics.  In this system plants are mounted vertically in growing tubes (Patent pending) to increase the growing space.  Solar pumps lift nutrient solution to the top of the tubes which then trickles down through the growing tubes, thereby aerating the solution with fresh oxygen.  Pumps are on 1 hour per 24 hour day.  The only loss of water is through plant evapotranspiration.

This is to our knowledge the most efficient growing system in the World!
