Hydroponics is a method of growing plants in a nutrient-rich solution rather than soil.
The word “hydroponics” comes from the Greek words “hydro,” meaning water, and “ponics,” meaning labor. It is a subset of hydroculture, a method of growing plants without soil using mineral nutrient solutions in a water solvent.
The history of hydroponics can be traced back to the ancient civilizations of the Egyptians and the Aztecs, who used to grow plants in water-based systems. However, the modern practice of hydroponics began in the early 20th century, when researchers such as William Frederick Gericke, Dr. Nathaniel Colgan, and Dr. William A. Setchell began experimenting with growing plants in nutrient-rich solutions.
During World War II, hydroponics was used to grow food in areas where the soil was unavailable, such as on Pacific islands and in desert regions. After the war, the technology was further developed and commercialized, and it is now used in various applications, including agriculture, horticulture, and even space exploration.
Today, hydroponics is a rapidly growing industry with many different systems and methods being developed and used. Some of the most common types of hydroponic systems include deep water culture, nutrient film technique, drip irrigation, and ebb and flow systems.
