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.”
