Ebb And Flow/Flood And Drain

Hydroponic ebb and flow system

             An ebb and flow hydroponic system uses a timed pump submerged in a properly ph'd(5.8-6.2)  aerated nutrient solution to periodically  flood and drain a growing table, on which plants are rooted in a hydroponic medium.(expanded clay pebbles, rockwool, coco coir filled pots, etc). The table would be slightly raised just above the reservoir to assure that proper return of the solution  to the reservoir will be achieved. The pump brings the solution up to the table and when the timer from the pump shuts off gravity returns the solution back to the reservoir.  The periodic  flooding keeps the root zone moist and well-fed, . This hydroponic system is not overly costly, is easy to maintain and is excellent for achieving great yields in small spaces.
