How does an ebb and flow hydroponics system work?

Similar to its name, an ebb and flow system flood's the root zone with nutrients, and slowly drain back into the reservoir. A water pump transports the nutrients into the flood table, along with a timer or controller which sets the flood and drain cycles. This happens 4-6 times a day, and the roots will soak in the nutrient solution for 10-15 minutes at a time.

While the nutrient solution soaks the root zone during the flood cycle, the plants are not exposed to oxygen. For this reason, it is very important to ensure adequate oxygen in the hydroponic grow media.
