Abstract: 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, and a control unit configured to control the circuits. The cultivation room comprising a plant bed 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. The cultivation plant comprises an adjacent facility frequented by carbon dioxide generating entities, the adjacent facility being arranged adjacent the cultivation room. The air circuit comprises an intake conduit configured to lead air from the adjacent facility to the air circuit.
