    abstract = {Due to a constantly increasing world population, a decrease of farm land, climate changes and food
safety concerns, many companies have gotten involved in plant factories that grow certain crops regardless
of the weather of environment. In the plant factory, the growing environment can be controlled and the crop
can also be controlled. As one of control factors, this study studies the effects on lettuce growth which varies
considerably by LED light intensity along the distance. For showing the effects, lettuce production in the plant
factory is compared and analyzed.}
