The ebb and flow hydroponic system works by periodically flooding a grow container with the nutrient solution and then letting container drain back to the reservoir. The system is sometime referred to as a flood and drain system. The flooding can be done manually but it is most often controlled by a timer and uses a pump to move the nutrient to the container and gravity to move it back. Like most media based hydroponic methods ebb and flow hydroponic systems can survive power failures because the media holds nutrient between waterings. The ebb and flow systems also have other advantages.
