When a lightweight growth material with good air permeability is used as the growth material 108, the roots of the plant 109 can be prevented from being damaged, and the load of the light growth material is, for example, about 1/3 of the normal land. For this reason, it is preferable that the load applied to the laying surface 300 can be reduced.

  As shown in FIG. 4, the water storage tank 200 disposed below the planting container 100 has a side wall 201 and a bottom plate 202 and has a substantially box shape with a square tray in plan view and an open top surface. The height of the side wall 201 is lower than the height of the support legs 107 a and 107 b of the planting container 100, and the upper end surface of the side wall 201 is the bottom plate of the planting container 100 in a state where the planting container 100 is placed in the water storage tank 200. It is arranged at a position lower than the lower surface of 102.

  The bottom plate 202 of the water storage tank 200 corresponds to the shape of the support legs 107a and 107b and the water absorption convex portion 105 at substantially the same position in plan view corresponding to the support legs 107a and 107b and the water absorption convex portion 105 of the planting container 100, respectively. The corresponding recesses 203a, 203b, 203c protrude downward and are recessed with the upper surface open, with substantially the same or similar shapes, and slightly larger than the lower ends of the support legs 107a, 107b and the water absorption protrusion 105, respectively.
