Ebb and flow hydroponic systems provide oxygen to the roots of the plant and nutrient intake, without sacrificing the speed of growth or the yield. Water is delivered intermittently, while the plant is in an inert medium, serving only as a stabilizer. Common mediums are clay pebbled or rinsed gravel. Tray and reservoir or an individual module configuration are two most widely used systems, the first being a single pump system and the other having dual pumps. Nutrients are delivered by pumps and returned by gravity. The selection of the pump is important, so the volume of the water and the height at which it will be delivered need to be considered. Ebb and flow systems, like other hydroponic systems improve their performance through additional aeration. Although these systems were one of the first hydroponic systems to be adopted, they are widely used due to its simplicity and effectiveness.
- Ebb and flow systems are very reliable, so they’re commonly used for hydroponics.
- There are two different kinds of the system that most gardeners use.
- Read on for details of each system and how to set up one for your own use.
“An ebb and flow system, also known as a flood and drain system, relies on intermittent water delivery (flood) to a plant or series of plants held in an inert medium.”
