Maximizing Cannabis Yields with Dr Bruce Bugbee

Dr. Bruce Bugbee gives a game-changing master class for cannabis growers on optimizing cardinal growth parameters to maximize yields (see below for time-stamps of topics). In the video he gives very specific recommendations for light levels, photo-periods, temperature, media, nutrients, humidity, and more. Bruce is a world-renowned professor and researcher at Utah State University’s Crop Physiology Lab, an ASA Fellow, president of Apogee Instruments, and is known for his extensive work with NASA plant growth systems. Bruce’s lab at USU received a license to research medical hemp in 2018 and has been conducting high-level research on strains and optimal cultivation methods to maximize CBD yields in hemp flower buds.
