The present invention provides a hydroponic cultivation apparatus set having high versatility of equipment and capable of small-scale pesticide-free cultivation without special knowledge about agriculture. A hydroponic cultivation apparatus uses a foamed polystyrene board 1 with a through hole as a base for fixing seedlings, floats the foamed polystyrene board 1 in a water tank 5 filled with liquid fertilizer 4, and increases the size and number of plants. In addition, it is selected whether the through hole is closed or not, and combined with a sponge 9 with a notch that is easy to soak in water, it is used as a foundation for cultivation. At the same time, the expanded polystyrene is colored not only in general white but also in other colors. [Selection] Figure 4【課題】設備の汎用性が高く、農業について特別な知識がなくても小規模な無農薬栽培が可能な水耕栽培装置セットを提供する。【解決手段】水耕栽培装置は、貫通穴の開いた発泡スチロール板１を土台として苗の固定に使用し、液肥４を満たした水槽５の中に発泡スチロール板１を浮かべ、植物の大きさと数に合わせて貫通穴を塞ぐか塞がないかを選択し、水のしみこみやすい切れ込みの入ったスポンジ９と組み合わせることで栽培の土台とする。それと同時に発砲スチロールを一般的な白色のみならず他の色にも着色する。【選択図】図４
