Hydroponics is a method of growing plants without soil, instead using a nutrient-rich water solution to deliver essential minerals and elements to the roots of plants. This method of gardening allows for more precise control over the plant's environment, leading to faster growth and higher yields compared to traditional soil-based methods. Hydroponics is often used in indoor gardening and greenhouse cultivation, making it a popular choice for urban farming and sustainable agriculture practices. Researchers in the field of hydroponics are studying different nutrient solutions, irrigation systems, and plant species to optimize growth and productivity in this innovative agricultural technique.
