Detailed explanation-1: -The water culture method is known as hydroponics or solution cul ture. Today, all methods of growing plants with nutrient solutions are known as “hydroponics” although technically the term refers to water culture only.

Detailed explanation-2: -Simply put, hydroponics is the practice of growing food in nutrient-enhanced water, without the use of soil as a growing medium. The roots are suspended in water, which is enriched with nutrients that would otherwise come from the soil and its organic matter.

Detailed explanation-3: -Hydroponics is the practice of growing plants without soil. The plants can be grown in a nutrient-rich solution, or in a disease-free substance such as sand, gravel or coconut fibre, watered with nutrient solution.

Detailed explanation-4: -The soil itself is not really needed by the plants-just the nutrients and water in it. So if the nutrients are put in water, the plants can get what they need to grow without the soil. For example, hydroponic is a technique of growing plants using solutions rich in mineral nutrients without soil.

Detailed explanation-5: -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.
