Then there’s geopolitics and the need to go green and sustainable. The Paris Agreement commits nations to cutting carbon emissions. That task becomes easier when they have adopted sustainable LED technology. Government LED subsidies will compel growers to make LED the new horticultural industry standard, and LED’s intrinsic efficiency and other advantages over high-pressure sodium (HPS) will help achieve that goal.
Apart from that, sustainable practices are increasingly an imperative in our economy—and that’s not only because they make for good optics and good ethics. It’s also because they’re good for business. Growers looking to go green are finding that adopting LED tech will boost their production levels or product quality even as it cuts their energy consumption and CO2 emissions.
As dimmable and dynamic grow lights and knowledge about how to improve production develop, LED’s ecological footprint will decrease even further. Such equipment will allow a grower to adjust lighting amounts and spectra in accordance with the needs of particular plants and from moment to moment, taking into account a crop’s developmental status, the amount of natural light that penetrates the facility, and so on.
The progressively more sustainable way greenhouses will be powered will also make LED increasingly relevant. The renewable energy sources, like wind and solar, that will assume a greater proportion of the energy mix generate direct current. That’s a much better fit for LED than it is for the HPS lighting that still dominates in horticulture.
