The carbon dioxide supply unit 960 is provided in the accommodation space 101 and may include a housing in which a space is formed so that solid carbon dioxide is injected therein, and a door that is openably provided on one side of the housing. Here, the housing may be made of a transparent material.

The average carbon dioxide concentration in air is about 400 ppm. The accommodating space 101 having a structure blocked from the outside properly controls the rotational speed of the intake part 200 and the exhaust part 300 when the external temperature of the housing 100 is between 0 and 17 degrees, and in some cases, the temperature By operating the control unit 700, it is possible to properly maintain the internal temperature of the accommodation space 101 to 20 ~ 22 degrees. However, when the external temperature of the housing 100 is 5 degrees or less or 18 degrees or more, the temperature is controlled by operating only the temperature controller 700 in a state in which the intake part 200 and the exhaust part 300 are stopped. In the state in which the lamp 520 of 500 is turned on, the concentration of carbon dioxide in the air is rapidly reduced due to photosynthesis, so that the plant does not grow properly. At this time, in order to artificially increase the concentration of carbon dioxide in the atmosphere, the concentration of carbon dioxide inside the accommodation space 101 may be adjusted by using solid carbon dioxide.

To this end, when the lamp 520 of the above-described lighting unit 500 is turned on, the control unit 900 may open the door of the carbon dioxide supply unit 960 to expose solid carbon dioxide to the air. In this case, solid carbon dioxide is vaporized while in contact with air. On the other hand, when the lamp 520 of the above-described lighting unit 500 is turned off, the control unit 900 may close the door of the carbon dioxide supply unit 960 to block solid carbon dioxide from contacting air. In this case, since vaporization of solid carbon dioxide is prevented, the carbon dioxide concentration suitable for photosynthesis can be maintained while minimizing the consumption of carbon dioxide.

Since it is possible to work inside, labor can be saved, and water generated during the humidity control process can be reused to minimize water use. In addition, the present invention can supply high-purity oxygen to the cultivation tank, so that a hydroponic cultivation environment can be created without a separate filtration structure, and the temperature of the receiving space can be maintained at a set temperature by adjusting the rotational speed of the intake and exhaust parts. Energy consumption can be reduced, and since the internal temperature of the accommodation space 101 is maintained uniformly, the growth rate of the crop 10 can be maintained constant.

In addition, the present invention can keep the cultivation conditions (temperature, humidity, carbon dioxide, etc.) of the accommodation space 101 constant regardless of the external climatic environment, so that the crop 10 can be grown in various environments, and the fish tank By monitoring the water temperature and water quality (ph, DO, salinity, ammonia, nitrite, nitrate) in real time, the feed amount can be automatically adjusted, and the ph can be automatically adjusted, making it easy to manage the water quality of the fish tank. In addition, the present invention can increase the efficiency of photosynthesis by appropriately vaporizing solid carbon dioxide according to the photosynthetic time (the time when the lamp is turned on) and the time when the photosynthesis is not (the time when the lamp is turned off), and spraying mist when the humidity is low It is possible to automatically maintain proper humidity by controlling the amount of fish feed input and maintain an appropriate level of nitrate concentration to automatically maintain optimal conditions for plant growth.
