1. A method of providing horticulture light to a plant in a horticulture arrangement, the method comprising:
providing during a controlling mode first horticulture light to the plant with an average intensity selected from a range of at least 150 μmol/m2/s,
wherein at least 15% of photons of the first horticulture light have a wavelength selected from a range of 700-800 nm, wherein at least 45% of the photons of the first horticulture light have a wavelength selected from a range of 640-700 nm, wherein at maximum 10% of the photons of the first horticulture light have a wavelength selected from a range of 400-500 nm, wherein percentages of the photons relate to a total number of photons in a spectral range of 400-800 nm, and
wherein the controlling mode includes providing the first horticulture light to the plant during one or more first time periods preceding a harvest and providing a second horticulture light to the plant during one or more second time periods preceding the harvest, the first time periods and second time periods do not overlap, the one or more second time periods are within a period of at maximum three days preceding the harvest, at least 20% of photons of the second horticulture light have a wavelength selected from the range of 400-500 nm, and at maximum 10% of the photons of the second horticulture light have a wavelength selected from the range of 700-800 nm.
