A hydroponic cultivation apparatus grows a plant by circulating a nutrient solution. The hydroponic cultivation apparatus includes: a hydroponic container configured to hold the nutrient solution； a support portion configured to support the plant； a nutrient solution supply unit configured to supply the nutrient solution to the hydroponic container； a nutrient solution discharging unit configured to discharge the nutrient solution from the hydroponic container； and a budding enhancer supply unit configured to supply a budding enhancer to the plant. Thereby, the hydroponic cultivation apparatus makes the plant produce a bud.
