Deep Water Culture
Deep Water Culture (DWC) is a method of growing plants without soil, where plant roots are suspended directly in nutrient-rich water. It's one of the most popular ways to grow plants in modern urban farming and indoor agriculture. Think of it as a way to grow plants in water instead of dirt, using special containers where the roots dangle in the water while the plant sits above in a net pot. Farmers and growers choose this method because it can produce larger yields in less space and uses less water than traditional soil farming. You might also see this referred to as "hydroponics" or "water culture growing."
