Sanitizing an agricultural facility by placing a chamber having an open interior within the agricultural facility. An item is placed within an open interior of the chamber and a door is interlocked. Then light having a spectral content within a narrow range of wavelengths is provided from at least one lighting device toward the item for a predetermined amount of time to inactivate a microorganism. Simultaneously, ozone may be discharged into the open interior to sanitize the item. Before the door unlocks the ozone within the interior of the chamber is directed to a filter for forming oxygen. Sanitizing the agricultural facility by detect humans, and in response, providing a first light with one spectral content when the human is detected, and providing a second light with a different spectral content within a narrow range of wavelengths to inhibit bacteria growth when humans are not detected.
