Ebb and Flood
With an ebb and flood system the water is delivered to each table by means of a water inlet. The table bottom has a hole so that part of the water flows away directly but at a rate which is less than the fill so the water level rises.
After a certain amount of time the water level reaches the desired height and flows away to the drainage gutter and into the greenhouse recirculation system.
Water inlets are available via curtain or straight flow pipe. The flow rates are 30, 60 or 70 LPM
