Classification: CPC A  H  Y | IPC A  H

Claim 14:
15. A control apparatus comprising:
circuitry configured to:
store, in a memory, correspondence information associating light characteristic information indicative of a characteristic of light with which leaf vegetables are irradiated, with quantified quality information having a quantified quality of leaf vegetables;
receive input of the quantified quality information; and
output a signal to control a light source to irradiate the leaf vegetables with light based on the received quantified quality information and the correspondence information,

wherein the stored correspondence information includes correspondence information for at least one quality of leaf hardness, leaf thickness, leaf color, sugar content Brix value, vitamin C, and antioxidant component content of the leaf vegetables,
the light characteristic information includes an integrated photosynthetic photon flux density of light, and
the setting includes setting a ratio between a photosynthetic photon flux density of the red light and a photosynthetic photon flux density of the blue light and setting a range of the integrated photosynthetic photon flux density in a manner that at least one quality of the leaf hardness, the leaf thickness, the leaf color, the sugar content Brix value, the vitamin C, and the antioxidant component content is constant regardless of a value of the integrated photosynthetic photon flux density.
