What is aeroponics?
Aeroponics dates back to the 1920’s and most of its history has developed along side the use of hydroponics and aquaponics. Aeroponics is the method of growing plants without the use of soil by delivering plant nutrients through a liquid fertilizer mixed with water. Allowing the roots to be exposed to more oxygen than compared to in soil, allows for more aggressive growth and less risk of pathogens. In the 1920’s, botanists grew plants using an aeroponic method (before it was officially considered aeroponics) so that they could study root growth of plants without soil in the way.
The emergence of hydroponics in the 1980’s brought back alternative growing methods into the mainstream when Walt Disney World used hydroponic growing in “The Land” attraction at Epcot Center. Modern aeroponic history began in the 1990’s with plant research at NASA. NASA performed growing experiments aboard the Mir Space Center to try and find a way to grow plants in space. What they discovered, led to the implementation of aeroponic growing in commercial greenhouses and farms. In effect, this use led to a deeper understanding of aeroponic technology as is new to the personal consumer market within recent years.
How does aeroponics work?
Water mixed with nutrients is delivered to a variety of plants by being sprayed directly onto the roots. This reduces the need for soil as plants grow in mid air.
