Drainage equipment for hydroponic cultivation containers

Abstract

This item is a drainage device that is attached to the drain outlet of a hydroponic cultivation container, as shown in Reference Figures 1 and 2, which show the state of use. When viewed from the front, this item has an inverted J shape, with a flange extending from the outer periphery of the long side and a suction port at the end of the short side. A spacer is attached to the underside of the flange to adjust the height of the suction port. When this item is attached to the drain outlet of a hydroponic cultivation container, the flange abuts against the periphery of the drain outlet via the spacer, and the suction port is positioned above the flange.
