Outside the warehouse in northwestern Spain, it's a freezing, foggy morning but inside it's balmy, the warmth and LED lights fooling 360 hop plants to flower as if it were late August. "In this warehouse, we control all the environmental and nutrient parameters and the lighting factors, using LED lights to provide the plant what it needs when it needs it," said Sagrario.
