1. Hydroponics

   Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in aqueous solvents. Terrestrial or aquatic plants may grow with their roots exposed to the nutritious liquid or in addition, the roots may be mechanically supported by an inert medium such as perlite, gravel, or other substrates.Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can affect rhizosphere biology and physiological balance of the nutrient solution by secondary metabolites. Transgenic plants grown hydroponically allow the release of pharmaceutical proteins as part of the root exudate into the hydroponic medium.The nutrients used in hydroponic systems can come from many different organic or inorganic sources, including fish excrement, duck manure, purchased chemical fertilizers, or artificial nutrient solutions.Plants are commonly grown hydroponically in a greenhouse or contained environment on inert media, adapted to the controlled-environment agriculture (CEA) process. Plants commonly grown hydroponically include tomatoes, peppers, cucumbers, strawberries, lettuces, and cannabis, usually for commercial use, and Arabidopsis thaliana, which serves as a model organism in plant science and genetics.Hydroponics offers many advantages, notably a decrease in water usage in agriculture. To grow 1 kilogram (2.2 lb) of tomatoes using intensive farming methods requires 214 liters (47 imp gal; 57 U.S. gal) of water; using hydroponics, 70 liters (15 imp gal; 18 U.S. gal); and only 20 liters (4.4 imp gal; 5.3 U.S. gal) using aeroponics.Hydroponic cultures lead to highest biomass and protein production compared to other growth substrates, of plants cultivated in the same environmental conditions and supplied with equal amounts of nutrients.Since hydroponics takes much less water and nutrients to grow produce and climate change threatens agricultural yields, it could be possible in the future for people in harsh environments with little accessible water to grow their own plant-based food.Hydroponics is not only used on earth, but has also proven itself in plant production experiments in space.

1. hydroponics

   Hydroponics is a method of growing plants without soil, where the plants are instead grown in an inert growing medium and receive nutrient-rich water solutions directly to their roots. This method allows the plants to receive a balanced intake of necessary nutrients, while also conserving water, as the water not absorbed by the roots can be reused. This system can be used to grow various types of plants including vegetables, fruits, herbs, and flowers.

1. Hydroponics

   Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions, in water, 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, mineral wool, expanded clay pebbles or coconut husk. Researchers discovered in the 18th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant's water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics. Hydroponics is also a standard technique in biology research and teaching.

1. Hydroponics

   A technique for growing plants in culture solutions rather than in soil. The roots are immersed in an aerated solution containing the correct proportions of essential mineral salts. (From Concise Dictionary of Biology, 1990)

Examples of hydroponics in a Sentence

1. Mamoru Kikuchi:

   With this indoor hydroponics cultivation, it wasn't necessary to desalinate the land, and with Japan's four seasons, you can't grow vegetables outside all year round.

2. Professor House:

   Imagine if someone were to finetune our system so that you could get 85 per cent of the carbon and nitrogen back from waste into protein without having to use hydroponics or artificial light, that would be a fantastic development for deep-space travel. It’s faster than growing tomatoes or potatoes.
