Cultivation device

A cultivation device used in an artificial light plant factory, the device comprising:

• a cultivation room having a closable inside via a cultivation room opening;
• a plurality of cultivation chambers including a plurality of stages in the cultivation room, wherein the cultivation chambers are arranged in the vertical direction;
• an air circulation device that supplies air adjusted to a predetermined condition to each of the plurality of cultivation chambers at a predetermined flow velocity so that the environment in the cultivation room can be kept independent from the environment of a work room in which a person works and in which the cultivation device is arranged, and collects and circulates the supplied air from the plurality of cultivation chambers;
• and
• a nutrient solution circulation device that supplies nutrient solution adjusted to a predetermined condition to each of the plurality of cultivation chambers at a predetermined flow velocity, and collects and circulates the supplied nutrient solution from the plurality of cultivation chambers,
• a control unit,
• wherein a plurality of sets of a cultivation plate and a nutrient solution tray are arranged in the plurality of cultivation chambers,
• the cultivation chambers each include a chamber opening and a chamber lid that can open and close the chamber opening, on one end side in a longitudinal direction,
• the cultivation room includes a cultivation room opening for inserting and removing the cultivation plate between the cultivation room and the work room, and a cultivation room lid for opening and closing the cultivation room opening, on the one end side in the longitudinal direction,
• the cultivation chamber can be kept closed by closing the chamber opening with the chamber lid,
• wherein the cultivation device further includes a first electric-powered hinge associated with the cultivation room lid and a second electric-powered hinge associated with the chamber lid, wherein the control unit controls the first and second electric-powered hinges to prevent the cultivation room lid and the chamber lid from being open at the same time further maintaining the cultivation environment independent from the temperature and humidity of the work room environment;
• wherein the cultivation room opening is entirely below and offset from the cultivation chamber opening.
