Plant Lighting Efficiency and Efficacy: μmols per joule

Plant lighting continues to be a hot topic, especially as light-emitting diode (LED) technology continues to advance. Growers commonly ask which type of lighting technology to purchase. Supplemental lighting using LEDs is usually more efficient, but the initial cost is higher than with high-pressure sodium (HPS) technology. The choice of lamp types involves multiple factors: Read more about Plant Lighting Efficiency and Efficacy: μmols per joule[…]
