"Yerba Buena, a CleanGreen™ Certified cannabis grower in Hillsboro [Oregon], prides itself on being a good steward of the Earth. Part of the company’s commitment to energy conservation involves looking for ways to reduce energy use. In an industry known for energy intensity, Yerba Buena became one of the first recreational cannabis growers to take advantage of Energy Trust’s technical assistance and cash incentives when the company replaced T5 fluorescent lighting in its vegetative room with tubular LEDs."
