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. These systems can be set up indoors or outdoors and are often used in urban farming and commercial agriculture. Hydroponics can conserve water compared to traditional farming, as it recirculates water and minimizes waste. This method is increasingly popular for growing vegetables, herbs, and even fruits.
