Hydroponic means growing without soil. From there, several different systems have been put together since the early sixties, starting mostly in England and Israel. Early systems were very basic, replacing soil by growing media like sand, peat moss or rockwool.
Why does it work? Because plants are not feeding on soil but on minerals hidden in the soil. The purpose of hydroponic agriculture is to make those minerals available to the plants directly through water. Modern hydroponic growing systems are using more and more water as a growing media, preventing depletion of natural resources such as peat moss or accumulation of residues like rockwool and other fibers.
While current lettuce production figures for greenhouse soil production show harvests of 108 plants/m2/year, HydroNov projects are harvesting up to 500 plants/m2/year in a wide variety of climate around the world. Produce is clean and free of any contaminants present in outdoor crops. Production schedule allow even harvest every day year round. See our videos for a description of the growing process.
