Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium (known as geoponics). The word "aeroponic" is derived from the Greek meanings of aero- (air) and ponos (labour). Aeroponic culture differs from both conventional hydroponics, aquaponics, and in-vitro (plant tissue culture) growing. Unlike hydroponics, which uses a liquid nutrient solution as a growing medium and essential minerals to sustain plant growth; or aquaponics which uses water and fish waste, aeroponics is conducted without a growing medium.[1][not in citation given] Because water is used in aeroponics to transmit nutrients, it is sometimes considered a type of hydroponics.
Methods[edit] High-pressure aeroponics is defined as delivering nutrients to the roots via 20–50 micrometre mist heads using a high-pressure (80 pounds per square inch (550 kPa)) diaphragm pump. Nutrient uptake[edit] Progressive Plant Growing is a Blooming Business. Progressive Plant Growing is a Blooming Business Soil. Water. Say that plants don't need them and people may think you've traded your cow -- and your good sense -- for a handful of beans. But NASA-sponsored plant experiments prove that you don't need soil and lots of water to grow a beanstalk that would make Jack proud. Plants have been to space since 1960, but NASA's plant growth experiments began in earnest during the 1990s. Image at right: These plants have developed healthy root systems without soil in a rapid-growth aeroponic system. In 1997, NASA-sponsored studies aboard the Mir space station studied adzuki bean seeds and seedlings, a high-protein Asian food crop.
While all of the seeds did well, those aboard Mir grew more than those on Earth. Results from NASA's research aboard Mir has contributed to rapid-growth systems now used on Earth. Aeroponic growing systems provide clean, efficient, and rapid food production. The suspended system also has other advantages. Aeroponic how to.
