To maximize the growth of plants, controlling VPD is applied by fog cooling in a plant factory with solar light. The spatial data of environmental information cannot be obtained without interpolation among the detected values by the allocated sensors. In this paper, we evaluated the errors between the interpolated values with Kriging and the detected values in the spring, autumn, and winter, respectively, in the plant factory with solar light. The experimental results show that the maximum error of the interpolated values using Kriging are within the acceptable error range, ±0.1kPa. Therefore, Kriging is useful for interpolation in the plant factory with solar light.
