X59 strainFound this info online....Selection of varieties for CBD This is one of the very important aspects growers must understand. If CBD is the focus of production, be aware that there is practically no information available on CBD contents of Health Canada approved varieties. In 2014, my colleagues at the Alberta Innovates Technology Futures facility in Vegreville and myself completed a one-year study screening four hemp varieties for CBD content and developing best management practices. We tested four varieties and selected X-59 because of its smaller size. Male plants were removed and all female plants were grown to maturity. In the final analysis, the CBD contents ranged from 0.36 per cent to 3.94 per cent, and THC was always below the limit of 0.3 per cent. It was also observed that at a density of five plants per square meter, average CBD was higher.
