Summary:PURPOSE: To effectively treat a culture solution for hydroponic culture, remove a growth-inhibiting substance secreted by the plant, etc., prevent the lowering of growth in continuous cropping and enable the continuous use of the culture solution over a long period by circulating the culture solution through a treating layer composed mainly of a fibrous activated carbon. CONSTITUTION: A culture solution for the hydroponic culture of plants such as green vegetables, fruits and flowers is treated by circulating the solution through a treating layer composed mainly of a fibrous activated carbon such as a fibrous activated carbon having a specific surface area of 500-2,000m /g and a volume of pores having pore diameter of <=30 accounting for >=90% of the total pore volume.
