About this episode
In this episode of Hydroponics Daily, we delve into the roles of sodium and metal halide lamps in hydroponic growing. Discover the differences between high-pressure and low-pressure sodium lamps, and why high-pressure versions were favored for plant growth despite their heat production. Learn about the advantages and limitations of metal halide lamps, including their popularity in America and their distinct white light. We explore the implications of the LED revolution on these older technologies, including the decrease in their availability as manufacturers pivot to LED development. Despite their decline, sodium and metal halide lamps remain relevant for certain growers, offering a balance of spectrum and heat beneficial for plant growth, especially in greenhouses. Join us as we illuminate the nuances of choosing the right lighting technology for your hydroponic setup, balancing factors such as cost, efficiency, and the specific needs of your plants. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/
