Answers
Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants (usually crops) without soil, by using mineral nutrient solutions in an aqueous solvent. Terrestrial plants may grow with only their roots exposed to the nutritious liquid, or, in addition, the roots may be physically 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. The nutrients used in hydroponic systems can come from many different sources, including (but not limited to) fish excrement, duck manure, purchased chemical fertilizers, or artificial nutrient solutions.
Plants commonly grown hydroponically, on inert media, include tomatoes, peppers, cucumbers, strawberries, lettuces, cannabis, and model plants like Arabidopsis thaliana
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 400 liters (88 imp gal; 110 U.S. gal) of water;[citation needed] 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. Since hydroponics takes much less water to grow produce, it could be possible in the future for people in harsh environments with little accessible water to grow their own food.
Answer:
Hydroponics or Hydroculture is the method of growing plants in the nutrients that they need instead of soil. The plant foods are simply put into water instead and it makes a solution for the plants to live in.[1] Vegetables, flowers and herbs can all be grown in water.
It is quite an old idea. The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum by Francis Bacon, printed a year after his death. Water culture became a popular research technique after that. In 1929, William Frederick Gericke of the University of California at Berkeley began publicly promoting that solution culture be used for agricultural crop production.[2] Oliver and Tintin are the pioners of Hydrophonics
Advantages
Hydroponic crops can be packaged and sold while still alive, increasing the length of freshness.
Over and under-watering is stopped.
Hydroponics is a good method of plant growing for areas without good soil, such as Antarctica, space stations, and space colonies.
Hydroponics is very good for plant teaching and research.
No soil is needed.
Crops are not contaminated with soil.
Less water is needed than with soil-grown crops.
Hydroponics cost less than other ways for growing strawberries.
Hydroponics give the plants more sunlight.
Bugs and other pest threats are reduced with a hydroponic system.
