According to an aspect of the present invention, a pneumatic control and air source device for crop cultivation is provided. Both wind and airflow are considered to solve the problems of pneumatic control and constant temperature. Around the cultivation area where the energy is restricted, the process of controlling the energy at a constant speed is performed. Unplanted areas are either constant or unstable. The differences between literature and patents are as follows. Unlike ZA Patent No. 200803785, the process and air velocity retention device of the present invention is for the movement of plant gases. This matter, then, diffuses carbon dioxide into the air flow and air in a planting system, using various types of directional controls. Unlike International Patent No. 204513637, the present invention is an air velocity retention device and process for plant airflow, which has different features and functions. It is the one air velocity retainer on the harvest rail (931), the roots of the plants, and the air flow within the plant growth system. Unlike International Patent No. 20131311072, several variants of "Process and apparatus for plant airflow" have been invented. This variant has different directions and device components focused on maintaining a constant air velocity and airflow through the crop. The present invention also solves the vertical harvest problem of distributing the rich carbon dioxide at the bottom of the harvest rail (931). The growth area at the top of the vertical harvest is not as good as at the bottom. If the height of the harvesting rail (931) is used for vertical harvest growth, crops planted in higher positions will grow less than in lower areas. Furthermore, occasionally the crest cannot grow. The essence of the present invention is a device that acts to mix carbon dioxide with other gases that are mixed with cooling air that affects plant growth. Also, to release the mixed air to the area where the crop is planted. The device maintain
