PROBLEM TO BE SOLVED: To provide a hydroponics device capable of giving an environment suitable for raising plants. SOLUTION: This hydroponics device has a liquid manure supplying means 7 which intermittently supplies liquid manure to a cultivation tank 1 and produces current in one direction of the liquid manure on the lower part of the cultivation tank 1, and a planting pot 22 which is inserted into a pot insertion hole 18 made on a top plate 17 of the cultivation tank 1, has an opening part on the upper and lower ends, and is filled with many pumice stones 26 in the inside. A gap allowing the root of a plant 21 planted on the planting pot 22 to grow is formed between the lower surface of the planting pot 22 inserted into the pot insertion hole 18 and the upper surface of a bottom plate 14 of the cultivation tank 1.
