Claims

[Scope of utility model registration request]

In a hydroponic cultivation method in which plants are grown using a solution containing nutrients essential for plant growth dissolved in water, a plurality of water channel devices that are open at the top to form water channels and are connected to each other through joints in the direction of water flow; The joint comprises at least a male thread for the joint and a female thread for the joint that connect the joint and the waterway device, and a hole is provided in the connecting portion of the waterway device through which the male thread is inserted;
The joint is bent in a direction perpendicular to the water flow direction to form an expandable part, and a connecting part of the joint is provided with a hole through which the male screw is inserted, and the water channel device, the male screw, and the female screw are made of synthetic resin. In the hydroponic cultivation device, at least the contact surface side of the joint with the water channel device is an elastic member through which the solution does not permeate.
