Ebb & Flow Systems

In the ebb & flow method (also known as the flood and drain method), the plants sit in their own container separate from the nutrient reservoir. On a set schedule, a pump transfers the nutrient solution from the reservoir to the grow tray where the plants are located, soaking the plant roots and the grow medium. The pumps then turn off, and the solution drains back into the reservoir. Read more.
