Ebb and Flow Hydroponics

Ebb and Flow, or Flood and Drain is a system involves the periodic flooding and draining of the nutrient solutions. The Flood is when the water and nutrients flow the growing areas, flowing over the plants’ roots. The drain is when the water drains back to the reservoir.

The ebb and flow system momentarily floods the grow tray with nutrient solution and then drains the solution back into the reservoir. It uses a submerged pump connected to a timer set to come on various times a day, depending on the type and size of your plants, humidity, temperature, and the growing medium used.
