1. An apparatus, comprising:a computer;
a grow light array operatively coupled to the computer; and
a sensor array operatively coupled to the computer;
wherein at least one sensor in the sensor array is movable independent of a grow light of the grow light array configured to provide a light output incident upon the at least one sensor;
wherein the sensor array is configured to determine a light spectrum sense parameter, generate a sense signal including the light spectrum sense parameter, and provide the sense signal to the computer;
wherein the computer is configured to receive the sense signal and provide a grow light signal to the grow light array to adjust a spectrum of light output from the grow light array to adjust the light spectrum sense parameter to match a desired light spectrum sense parameter.
