Hydroponics is system where plants are grown without soil, but fed mineral-enriched water. Some may say the use of hydroponics is urban farming, because hydroponics can occur in any indoor facility as long as the following are controlled: light, temperature, water, CO2, oxygen, pH and nutrients. Aeroponics is a branch off of hydroponics; it is where the plant is suspended in a chamber of air and is misted with mineral enriched water in timed intervals.
The word hydroponics is comprised of two Greek words: ‘hydro’ (water) and ‘pono’ (labor). Through the use of an old method we could grow the necessary plants in a short period of time and space. Hydroponics has made appearances in the gardens of the Babylon, the Aztecs and the Chinese. It also dates back to almost 700 years BCE in Egypt.
