Anthroponics is a way of growing plants without soil. You use water with nutrients added to it that the plants need to grow. The water is either flowing in a continuous cycle (like a river) or can be used again and again (recycled). The roots of the plants are usually held in a container filled with rocks or other solid materials. With anthroponics, you can grow more plants in a smaller space and with less effort. It is a very efficient way to grow food.
