It's also becoming possible to grow plants hydroponically in a highly automated and controlled environment (warehouse/cattle shed), with up to a 98% saving in treated water usage, 60% less nutrients required but with more nutritious crops and no pesticides. This is the case for High Pressure Aeroponics, which is slightly more complex than other hydroponic methods. https://spinoff.nasa.gov/Spinoff2008/ch_3.html https://spinoff.nasa.gov/Spinoff2008/ch_3.html
