Hydroponics is a method of growing plants using mineral nutrient solutions, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, or mineral wool.

Hydroponics can increase yields of commercial crops because plants are grown closer together than in the field; it also eliminates weeds and pests.

Hydroponics allows automation of cultivations: temperature, lighting, pH and nutrients concentration control and ventilation. Hydroponics is also a standard technique in biology research and teaching.

The two main types of hydroponics are:
Solution Culture
Medium Culture
Solution culture does not use a solid medium for the roots, just the nutrient solution. The three main types of solution culture are static solution culture, continuous flow solution culture and aeroponics.

The medium culture method has a solid medium for the roots and is named for the type of medium, e.g. sand culture, gravel culture or rockwool culture. There are two main variations for each medium, sub irrigation and top irrigation.
