Claim 0:
1. A horticultural lighting fixture configured to emit a spectrum including
a first spectral feature in the form of a spectral peak having its peak wavelength in the blue wavelength range of 425-475 nm,
a second spectral feature in the form of a spectral valley having its base value in the cyan wavelength range of 475-500 nm,
a third spectral feature in the form of a broad-band spectral feature extending throughout the green wavelength range of 500-600 nm, and
a fourth spectral feature in the form of a spectral peak having its peak wavelength in the red wavelength range of 625-675 nm,, wherein
the fourth spectral feature has a maximum relative emission intensity that is the highest relative emission intensity within the spectrum,
the first spectral feature has a highest relative emission intensity that is non-zero but less than the maximum relative emission intensity,
the third spectral feature has a highest relative emission intensity that is non-zero but less than the maximum relative emission intensity, and
the base value of second spectral feature is below all relative intensities of the third spectral feature.
