Growing the future. High-tech farmers are using LED lights in ways that seem to border on science fiction

Since plants emerged on Earth, they have relied on the light of the sun to feed and grow through the process of photosynthesis.
But Zelkind is part of a radical shift in agriculture — decades in the making — in which plants can be grown commercially without a single sunbeam. A number of technological advances have made this possible, but none more so than innovations in LED lighting.
“What is sunlight from a plant’s perspective?” Zelkind asks. “It’s a bunch of photons.”
