Flood Tables and Trays are useful to gardeners who need a strong base for a garden or are looking to build their own custom flood and drain system. Flood tables have hard plastic sides to contain water and can hold both hard-walled containers and rockwool cubes as individual planting …sites. A flood table floods when it is filled with water, which feeds the various plants situated in the table. Afterwards, if connected with a bulkhead or drain, the water will drain out either into a reservoir to be recirculated or a drain-to-waste setup where water is flushed and not reused.
