An air movement control and air source device for cultivation is presented. It mixes carbon dioxide and other gases those can affect the growth of plants (001, 002, 003). The mixed air is released to the area where the plants (001, 002, 003) are planted. Air velocity retention devices (110, 111, 112) are used to maintain the speed of air flow. The air movement control and air source device can help to make the carbon dioxide concentration around each plant (001, 002, 003) uniform.
