PROBLEM TO BE SOLVED: To provide a plant growth bed and a plant growth bed set in which, in water culture, algae are difficult to be adhered thereto and can be easily removed, which are light weight and can be easily moved, and excellent in durability.SOLUTION: A plant growth bed 1 comprises: a plurality of pot parts 11 formed of a flat resin plate, and hold a germination bed； an air reservoir space 15 floating on a culture fluid； and a collar part 10 serving as deformation suppression means for suppressing deformation of a peripheral side wall 12. Even when the resin plate is thin, the peripheral side wall 12 is difficult to be lifted up, the plant growth bed is excellent in durability, is light weight and can be handled easily.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】水耕栽培において、藻を付着させにくくかつ除去しやすく、軽く、移動容易であることに加えて、耐久性に優れた植物育成床および植物育成セットを提供する。【解決手段】平滑な樹脂板からなり、発芽床を保持させる複数の鉢部１１と、培養液に浮かぶ空気溜空間１５と、周囲側壁１２の変形を抑制させる変形抑制手段をなす鍔部１０とを備えさせ、樹脂板が薄く成形されていても、周囲側壁１２が捲れあがりにくく、耐久性に優れ、軽くて取り扱いやすい植物育成床１。【選択図】図１
