PROBLEM TO BE SOLVED: To provide a crop growth system in which optimum growth management of a crop can be performed by conducting temperature management and fertilizer control by grasping growth condition of the crop and using an algorithm that corresponds to the growth condition.SOLUTION: The crop growth system comprises chambers for retaining crops, a nutrient liquid feeder for feeding nutrient liquid to the chambers, a growth condition sensor for grasping growth condition of the crops, and a main controller for controlling at least one of fertilizer concentration and nutrient liquid temperature of the nutrient liquid for each chamber according to an algorithm that corresponds to growth condition of the crops grasped by a signal of the growth condition sensor. |
