These certifications, such as the Medical Marijuana Seal, come from seed banks that follow rigorous standards when it comes to certifying their cannabis seeds. The Medical Marijuana Seal will be included on the packaging of the cannabis seeds, so you’ll know exactly what you’re purchasing. Seed banks that do not offer a certification are not reliable or reputable enough to provide any certification. The Medical Marijuana Seal is currently the most widely used certification, but there are other certification seals available. Some of the other certifications include the Hemp Seed Seal, Kiva's Seal, and the European Seed Testing Council (ESTEC). Other certifications that are available include, the Global Certification Program (GCP) for the cannabis seed industry. This certification is available from both seed banks and growing companies and is currently considered to be the gold standard. The Global Certification Program is also used for hemp seeds.
