Judging Seeds By Appearance

Dark tiger striped seeds are often described as mature and pale ones as duds, but that rule breaks down constantly across different CBD lines. Size and colour vary by strain, and a small light seed from a good breeder will usually outperform a fat dark one of unknown origin. What the seed selection notes on https://calmcbdseeds.com stress instead is a firm shell that does not crush under gentle pressure and a recent packing date. Visual sorting has thrown out more good seeds than bad ones in my experience.
