General Research on Hydroponics

 Since the topic is new, research was done to better understand "Hydroponics".

According to this patent, hydroponics is a method of growing plants in nutrient solutions with or without the use of an inert medium to offer mechanical support, such as gravel, vermiculite, rockwool, peat moss, saw dust, coir dust, coconut fibre, and so on. Hydroponics is derived from the Greek terms hydro, which means water, and ponos, which means labor, and literally translates to "water work." Professor William Gericke invented the term hydroponics to describe growing plants with their roots floating in water containing mineral fertilizers in the early 1930s.

Not only is cultivable land shrinking as a result of growing urbanization and industrialization, but so are traditional farming techniques, resulting in different of severe environmental effects. Methods for raising enough food must evolve in order to sustainably support the world's rising population.

Agriculture without soil includes:

• Hydro agriculture (Hydroponics)
• Aqua agriculture (Aquaponics) 
• Aerobic agriculture (Aeroponics)

Crops can be grown using hydroponics are leafy vegetables, tomatoes, cucumbers, peppers, strawberries, and many more. 

The purpose of this patent covers different aspect of hydroponics, vegetables grown in hydroponics system and global hydroponic market.

Wick, drip, ebb-flow, deep water culture, and nutrient film technology (NFT) are all common types of systems.

Types of systems:

• Wick System
• Deep Water Culture System
• Dutch Bucket System
•  Drip System
• Nutrient Film Technique (NFT)
• Ebb-Flow System
• Aeroponic System

Plant nutrients used in hydroponics are generally inorganic and ionic types and are dissolved in water. Different chemical combinations provide all 17 required elements for plant growth.
