Hydroponics is a subset of , which is a method of growing plants without soil by instead using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the nutritious liquid, or the roots may be physically supported by an inert medium such as perlite or gravel. The nutrients used in hydroponic systems can come from an array of different sources, including (but not limited to) from fish excrement, duck manure, or purchased chemical fertilisers.

dbo:abstract
  • Hydroponics is a subset of , which is a method of growing plants without soil by instead using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the nutritious liquid, or the roots may be physically supported by an inert medium such as perlite or gravel. The nutrients used in hydroponic systems can come from an array of different sources, including (but not limited to) from fish excrement, duck manure, or purchased chemical fertilisers. Plants commonly grown hydroponically include tomatoes, peppers, cucumbers, lettuces, and marijuana. Hydroponics offer many advantages, one of them being a decrease in water usage for agriculture. To grow 1 kilogram of tomatoes in Intensive farming requires 400 liters of water, in hydroponics 70 liters of water, and only 20 liters of water for Aeroponics. Because of the lack of water needed to grow produce, it would be possible in the future for harsh environments which don’t have much accessible water, to be able to grow their own food. (en)
