12. A method for controlling a growth of a plant in a greenhouse, the method comprising:
-
measuring an oxygen partial pressure within the greenhouse, said oxygen partial pressure related to a photosynthetic activity of a plant in the greenhouse, measuring at least one level including at least one of a glucose level and a starch level of the plant; transmitting the value of the oxygen partial pressure to a computerized control element, determining an optimal amount of light for a desired growth of the plant depending at least in part on the measured oxygen partial pressure and the measured level, and adjusting an actual amount of light emitted by a lighting element to the optimal amount. - View Dependent Claims (13, 14, 15, 16, 17)

18. A controlling device for a greenhouse, the controlling device comprising:
-
a computerized control element, a lighting element comprising a plurality of light-emitting elements for illuminating a plant growing in the greenhouse with light including a grow light component and a control light component, the plurality of light-emitting elements including; a first group of light-emitting elements comprising a grow light unit providing the grow light component to the plant, wherein the first group of light-emitting elements includes at least blue light-emitting elements emitting blue light and red light-emitting elements emitting red light, and a second group of light-emitting elements comprising a control light unit providing the control light component to the plant, wherein the second group of light-emitting elements includes at least blue light-emitting elements emitting blue light and green light-emitting elements emitting green light, and at least one first detector element for measuring an oxygen partial pressure in the greenhouse, and wherein computerized control element is configured to control an amount of the light emitted by the light emitting element, based, at least in part, on the measured oxygen partial pressure, wherein the computerized control element is configured to control a percentage of blue light within the grow light component to be from 80% to 90% of the grow light component and to control a percentage of red light within the grow light component to be from 10% to 20% of the grow light component, and wherein the computerized control element is configured to adjust the control light component to influence at least one of a blooming of the plant, a propagation of the plant, and a size of the plant. - View Dependent Claims (19, 20)
