Hydroponics is a method of growing plants in water without soil. It is type of horticulture and subset of Hydro culture. The water must be enriched with nutrients and the plants need some type of inert medium to support the root system. The research gaps were identified after the detailed review of literature. Extant literatures show that Hydroponics farming is more efficient and high yielding. But very limited studies are made in comparison with the traditional farming. Few studies also examined that there is less awareness about Hydroponics farming to the people. Also, there was not detailed study about challenges regarding hydroponics farming and subsidies which help to setup it. Thus, we are trying to fill this gap through our study
