Youtube's Best Cannabis Marijuana Weed Growing Videos - Cannabis Grow Lighting Myths and FAQs with Dr. Bruce Bugbee

Dr. Bruce Bugbee debunks myths and answers FAQs on grow lights for cannabis based on his research so far at Utah State University's Crop Physiology Lab (see time-stamps below to navigate topics) and the next video in the series here: https://youtu.be/JwtkHxv_3pU . Bruce is a world-renowned crop physiology professor famous for his work in controlled environment agriculture for NASA and is president of Apogee Instruments, a developer of research-grade instruments used in precision agriculture. Bruce's lab at Utah State is one of the few with a license to study cannabis cultivation with several active research projects underway (see: https://www.usu.edu/today/?id=58336 ). The lab's license is to research hemp, but these principles apply to marijuana, including sativa and indica. Some of Bruce's answers in this video are based on what the research is showing so far, but further tests are underway. As this is a very hot topic right now, we will do our best to monitor questions posted in the comments below and ask Bruce to answer them in future videos.
