Abstract Plants may be grown in water without soil using a technique called hydroponics. It is a subset of hydro farming and a sort of horticulture. The plants require some sort of passive medium for sustaining the root system, and the water must be supplied with nutrients. The basis of hydroponic farming is a technique that, among other things, replaces soil with a solution of nutrient-rich water are seen as a far more sustainable method than traditional agriculture since they use so few resources. Furthermore, hydroponic plants may be grown inside. Growing plants don't always need soil. It alone offers all the macronutrients and micronutrients required for plant growth and development. The disadvantages of soil-based traditional agriculture include soil deterioration, excessive use of chemical fertilizers, waste of irrigation water, high land requirements, etc. The need for a significant amount of nutrient-dense food to meet the huge demand of the global population warrants the introduction of new and sophisticated technologies and practices in agriculture that synchronize water and nutrient requirements to produce the highest yield.
