Soilless culture, also known as hydroponics, is a method of growing plants without the use of traditional soil as a medium. Instead, plants are grown in nutrient-rich water solutions or inert mediums such as perlite, gravel, sand, or coconut coir. This method allows for more precise control over nutrient levels, water usage, and environmental conditions, leading to faster growth rates and higher yields. Soilless culture is commonly used in commercial agriculture, urban farming, and home gardening. It is also a sustainable approach to farming that can help conserve water and reduce the use of pesticides.
