There is provided a solid shape information generation system to form a solid shape object suitable to cultivate a plant. The solid shape information generation system includes a forming information generator that generates forming information to form a solid shape object used to cultivate a plant using a first material and a second material based on information representing the solid shape object and form an area where at least the plant is sown using the first material whose tensile strength is lower than that of the second material; and an output unit that outputs the forming information for a solid shape forming unit to form the solid shape object.
