Hydroponics is a method of growing plants without soil, using mineral nutrient solutions in a water solvent. In hydroponic systems, the roots of the plants are either supported by an inert medium such as perlite, gravel, or other substrates, or the roots are suspended directly in the nutrient solution. This method allows for precise control over the nutrients the plants receive, as well as other environmental factors such as temperature, humidity, and light. Hydroponics has several advantages over traditional soil-based agriculture, including faster growth rates, higher yields, and the ability to grow plants in areas where soil is unavailable or unsuitable. It also allows for more efficient use of water and nutrients, as the nutrient solution can be recirculated and reused. Hydroponic systems can range from small-scale setups for home gardeners to large commercial operations. The technique is widely used in the production of leafy greens, herbs, and other high-value crops, as well as in research settings for studying plant growth and nutrition. While hydroponics requires careful management and monitoring of the nutrient solution and other environmental factors, it has proven to be a viable and sustainable method of crop production, particularly in urban and controlled environment agriculture settings.
