PROBLEM TO BE SOLVED: To enable the manifestation of characteristics possessed by an organic fertilizer to the maximum by preventing a mold from growing in a pipe, a liquid feed pipe and a tube and a discharge outlet and enabling the stable liquid feed of a culture solution using an organic fertilizer which could not conventionally be used for the hydroponic culture for a long period. SOLUTION: This organic culture solution is obtained by mixing an organic substance such as an amino acid, an organic phosphoric acid or chitosan with an organic liquid fertilizer containing nitrogen, phosphoric acid, potassium, sulfur, lime, magnesium and a minor element and acidic water prepared by electrolyzing water containing potassium chloride, thereby preventing a mold from growing when using an organic liquid fertilizer and enabling the stable liquid feed as an organic culture solution. As a result, a way is opened for cultivation in which an organic substance is used for the hydroponic culture merely enabling the conventional use of an inorganic fertilizer. |
