Dr. Coco from www.cocoforcannabis.com returns to the show, this time to explore the truth about grow lights. Dr. Coco discusses the recent research he has been working on with his partner, and what the compiled data has shown him. This leads to a conversation about grow light metrics, specifically PPF, and what exactly is going on when measuring PPF in various ways. He then talks about wattage, and the misconception that wattage can accurately translate to any sort of output expectation when it comes to LEDs. Dr. Coco extrapolates on the different types of LEDs that are currently manufactured, including LEDs with COB systems, and the prolific new "printed circuit board" style, also known as quantum boards.
