As a result, even during cleaning of the drain pipe 20, sunlight that causes the occurrence of blue sea cucumbers, weed seeds and pathogens enter the cultivation tank 10, and the culture solution supplied to the culture medium 17 Evaporation into the atmosphere can be prevented, and the vine plant 8 can be grown more reliably.

  Moreover, in the cultivation apparatus 1, since the drain pipe 20, the cleaning lid 30, and the cultivation tank 10 are each formed from a light-shielding material, sunlight can be prevented from entering the cultivation tank 10, so Occurrence can be suppressed. Therefore, the vine plant 8 can be grown more reliably.

  Moreover, in the cultivation apparatus 1, the inside of the cultivation tank main body 10A is partitioned into the drainage space 11A and the storage chamber 11B by the isolation wall 15, and the opening end 23 on the downstream side of the drainage pipe 20 extends from the drainage port 13A to the drainage port 13B. Protruding from the isolation wall 15. As a result, surplus culture solution taken into the drain pipe 20 from the perforations 21 is discharged into the drain space 11A and then discharged from the drain port 13B to the recovery pipe 6. That is, the surplus culture solution can be discharged to the collection tube 6 without connecting the drain tube 20 and the collection tube 6. For this reason, it becomes possible to push out the root of the climbing plant 8 from the upstream opening end 22 of the drainage pipe 20 to the drainage space 11A through the downstream opening end 23, and the drainage pipe 20 can be cleaned more easily.
