Ebb & Flow System
By: Cody E. & Cole E.
Parts: bedding tray, fill drain, reservoir, pump, overflow.
This system works best for plants smaller than 24 inches. Nutrients are stored in the reservoir and is pumped up a tray. The pump is controlled with a timer. When the pump turns off the solution flows back down the drain and out the pump. Ebb and flow is one of most reliable and easy to build hydroponic systems.
They are often found in greenhouses, used commercially by bedding and potted plants.
