Soilless culture is a method of growing plants without the use of soil. Instead, it utilizes nutrient-rich solutions or inert growing media, such as coconut coir, perlite, or rock wool. This technique allows for better control over nutrients and water, leading to faster plant growth and higher yields. This method is commonly used in hydroponics and aeroponics, where plants receive essential nutrients directly through water or air. Soilless culture can be applied in various settings, including greenhouses and indoor farms, making it a popular choice for urban agriculture and sustainable farming practices.
