research on hydroponic system based on 5Ws(who,what ,where,when and why)
Answers
Answer:
Hydroponics[1] 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.[2] Terrestrial plants may grow with 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.[3] Despite inert media, roots can cause changes of the rhizosphere pH[4] and root exudates can affect rhizosphere biology.[5]
