Hydroponic systems are methods of growing plants without soil, using nutrient-rich water instead. This technique allows for precise control over the nutrients and water that plants receive, leading to faster growth and higher yields. Common hydroponic systems include Nutrient Film Technique (NFT), Deep Water Culture (DWC), and Ebb and Flow systems, each with its own advantages and applications. These systems can be set up indoors or outdoors, making them versatile for various environments. Hydroponics is often used in urban farming and commercial agriculture, as it requires less space and water compared to traditional soil-based farming. Additionally, it can reduce the risk of pests and diseases.
