I have heard alot about high CBD , and was wondering, are there particular starins? Or as I saw on weed wars, you let the bud go longer in flower, thus producing more cbd's and less thc? I had heard there were specifif strains that were high cbd, then I heard that weed waars growers explained that is how you get high CBD. I am confused, and was hoping that some of our very learned growers could explain how it works? I am just confused, because I heard that Stanford University, they are working with High CBD strains. Thanks for helping me figure this out.
