Based in Portland, Phylos is best known for their autoflowering, feminized hemp seeds. The company has also invested in several years of pioneering hemp genotype testing and cataloging. The result of Phylos’ research, is Phylos AutoCBD. - A new hemp seed variety that should be on every cannapreneurs’ radar because of it's ease of growth, short-season/speedy growth (75 day average) and consistent high CBD flowers. With lab-verified feminization rates regularly at or exceeding 99.98%+, and with grow conditions tested in over 35 different U.S states, the AutoCBD seed type is one of the highest quality, most reliable CBD genetics available for purchase today. But, as they say on TV, there's more! Not Just a Hemp Seed Company High-yield CBD hemp strains are the Holy Grail of hemp growers and seed suppliers. However, cannapreneurs and established hemp growers often have to fly blind when ordering from hemp seed distributors. As it stands, few hemp seed suppliers can guarantee hemp seed feminization rates, predict flower yields, or guarantee final plant CBD to THC ratios. Now, though, with Phylos, things couldn’t be more different. How can Phylos be so confident in their product? Well, that's because unlike other popular seed companies, Phylos business extends beyond just seeds and also includes lab-verified genome and plant sex testing. This means they have years of experience testing a multitude of different seeds, so they have both the equipment and expertise to guarantee quality. <img class=aligncenter size-large wp-image-25
