Abstract

A lighting system comprising a light source, a controller operably coupled to the light source, and a timekeeping device operably coupled to the controller. The controller is configured to receive a selected action time associated with an agricultural product. The agricultural product includes an associated circadian rhythm defining an optimal action time range. The controller is configured to determine a lighting schedule responsive to the selected action time, the optimal action time range, and a time of day indicated by the timekeeping device, the lighting schedule being configured to impose a circadian rhythm on the agricultural product to shift the optimal action time range such that the selected action time coincides with the optimal action time range. The controller is configured to operate the light source according to the lighting schedule.
