grown in cultivation racks to maximise the use of high ceilings. The result is a 10 000-head daily harvest. The success of the project has led to en- quiries from interested parties across the globe and has the partners looking to develop other LED-lit farms in Japan. Key questions to ask when designing horticultural lighting: Does the light generate enough, and the correct ratio of, photons? Are the valuable photons going where they are needed, and how efficient is the luminaire at gen- erating those photons? When it comes to the future of horticulture, LED lighting offers a more robust food supply. And there are no doubt other advantages that have yet to be discovered.
