A dual-structure flower pot capable of controlling an amount of air flowing into a flower pot by a ventilation control device is provided to control humidity, an amount of air and temperature in the flower pot and effectively prevent disease damage of plants. A dual-structure flower pot to achieve easy control of air comprises: an inner vessel(10) with a plurality of vent holes(11); and a closed outer vessel(20) with an opening part on the lower surface. The inner vessel is inserted into the outer vessel to form a space part between the inner vessel and outer vessel. Air introduced through the opening part of the lower surface is outwardly discharged after passing the space. The amount of air in the outward discharge of air is controlled by a ventilation control device. A protrusion part(12) on the outside of the inner vessel supports the inner vessel to prevent it from being swung while maintaining the distance between the inner vessel and outer vessel constant. A central ventilation pipe(16) made of plastic
