The ebb and flow irrigation system is the most common plant production system in modern greenhouses. It is also suitable for the cultivation of ornamental plants and seedlings.
Ebb and flow irrigation is a closed irrigation system. Irrigation water mixed with fertilizer is pumped onto trays, and the plants on the trays begin to absorb the water and the fertilizer added to the water. After a period of time, the trays are emptied and the remaining water that is not absorbed by the plants is drained back into a central collection tank.
The water is filtered and treated before being recycled. After filtration and UV disinfection, the water is mixed with the required amount of fertilizer and reused.
