1. A cultivation plant comprising a cultivation room comprising an air circuit, a water circuit, a heat circuit, a light circuit, a nutrition circuit and a spacing circuit,
the cultivation plant comprising a control unit configured to control the circuits,
the cultivation room comprising a plant bed for plants, and
a plant yield control unit configured to give input on growth and/or quality of the plants to the control unit,
the control unit being configured to store driving parameters for the circuits and correlated input from the yield control unit,
wherein the cultivation plant comprises an adjacent facility, the adjacent facility being arranged adjacent the cultivation room, wherein the air circuit comprises an intake conduit configured to lead air from the adjacent facility to the air circuit wherein the air circuit comprises a dehumidification unit configured to dehumidify air in the air circuit,
wherein the dehumidification unit comprises an air inlet configured to receive air from the air circuit and an air outlet configured to feed dehumidified air to the plant bed,
wherein the dehumidification unit comprises a water outlet configured to feed condensed water to a water inlet of the water circuit that in turn comprises a water outlet that feeds water to an inlet of the nutrition circuit that in turn comprises an outlet that feeds nutrition water to the plant bed,
wherein the dehumidification unit comprises a heat circuit exchanging heat with the adjacent facility, wherein the plant bed comprises cultivation profiles extending in a length direction (X), a width (Y) direction and a height direction (Z),
wherein each cultivation profile comprises a bottom wall extending in the width direction (Y) and the length direction (X) and side walls connected to each side of the bottom wall and extending in the length direction (X) and the height direction (Z), wherein the bottom wall is configured to lead the water in and out from the water circuit,
wherein the cultivation profile comprises a top wall opposing the bottom wall and covering the side walls, wherein the top wall comprises openings for receiving plants to be cultivated,
wherein the light circuit is configured to feed light to the plant bed, and
wherein the spacing unit is configured to space plants apart in the plant bed over time.
