An artificial soil medium 100 includes a plurality of artificial soil particles 50 including a base 10 capable of absorbing and releasing moisture. The plurality of artificial soil particles 50 include a plurality of types of artificial soil particles 50 having different moisture absorption and release characteristics indicating a state in which the base 10 absorbs moisture or a state in which the base 10 releases moisture. The plurality of types of artificial soil particles 50 are configured to allow moisture to move between the different types of artificial soil particles 50.
