PROBLEM TO BE SOLVED: To provide a management system for a plant cultivation room and a management control method for a plant cultivation room capable of regenerating zeolite used in the plant cultivation room with a simple configuration. SOLUTION: A dehumidifier that dehumidifies the exhaust gas by adsorbing the moisture of the exhaust gas generated by the combustion treatment to the zeolite in the dehumidification tower, and adsorbs CO2 to the zeolite in the storage tower when the dehumidified exhaust gas flows in A CO2 supply device for supplying CO2 into the cultivation room by desorbing CO2 adsorbed on the zeolite in the storage tower when air having a low CO2 concentration is introduced, and in the dehumidification tower The heater for the dehumidification tower that heats the zeolite, the heater for the storage tower that heats the zeolite in the storage tower, and when the regeneration treatment timing of the zeolite in the dehumidification tower arrives, the heater for the dehumidification tower is turned on, and the storage tower And a control device that turns on the heater for the storage tower when the timing of the regeneration treatment of the zeolite inside comes.
