PLANT CULTIVATING APPARATUS

In a plant cultivating apparatus for cultivating plants by using an artificial light source, partition walls having a high light reflectance are arranged in a cultivation area to divide the cultivation area into small spaces and in each small space a light-reflecting plate is arranged, and the distance between the artificial light source and the plants is narrowed to irradiate the plants with a light having a low illuminance. In accordance with a preferred embodiment, there is provided a plant cultivating apparatus comprising sets of pallets which have plants placed therein and are arranged in rows in a growing chamber where environmental conditions are artificially controlled and which are moved in a direction orthogonal to the row direction in accordance with the growth of the plants, wherein all the peripheral surfaces of the growing chamber are covered with a reflecting plate having a high light reflectance, low-illuminance artificial light sources for emitting a light of low illuminance being arranged so that the distances between the light sources and plants are narrowed, and the spaces between the rows of pallets are 1.1 to 1.5 times the spaces between the plants when the plants are set just close enough that adjacent plants do not overlap each other. ?
