PROBLEM TO BE SOLVED: To improve the efficiency of plant growing in a plant growing device provided with a growing chamber for growing a plant.SOLUTION: A plant growing device 1 is provided with a ventilation unit 6 including an intake unit 61 for taking air into a growing chamber R, and an exhaust unit 62 for exhausting air from the growing chamber R. The intake unit 61 has an intake port 63, an intake damper 64 for opening and closing the intake port 63, a blower 65 for sending air in the direction of the growing chamber R, a passage 66 for guiding air to the upstream side of the blower 65, and a circulation damper 67 for opening and closing the passage 66. The exhaust unit 62 has an exhaust port 68, and an exhaust damper 69 for opening and closing the exhaust port 68. The ventilation unit 6 operates under either an intake/exhaust mode for taking air into and exhausting air from the growing chamber R or a circulation mode in which air is caused to circulate in the growing chamber R. By switching between these modes, COis taken into the growing chamber R and gas density, temperature, and humidity within the growing chamber R can be made uniform, and as a result, the efficiency of growing a plant P can be improved. |
