Does anyone know if Colorado is enforcing seed traceability? That is one of the rules according to Washington's I-502 (http://www.liq.wa.gov/publications/Marijuana/I-502/I-502_Dra... crtl-f "Traceability"). Theoretically, that means the Feds would be able to know where the pot came from if it was found out of state. If implemented effectively, that would negate some of the worry about the product ending up in the wrong hands.
Indeed, most growers 'clone' their plants as a propagation technique (cuttings). This style, growing a mother plant from seed and then taking hundreds of cuttings which grow into full size plants, ensures consistency and is faster than starting each plant from seed. Growers often swap trimmings rather than seeds, and they're sold in dispensaries.
Our laws are very friendly to the small homegrower, much like our laws on brewing. Nothing legally stops me and you from trading strains and seeds without telling anyone or registering anything. You can give freely if you dont charge, grow 6 plants per adult (3 budding), and all needed equipment is legal too. We've already had our first hemp crop, which was grown for as many seeds as possible, and many more acres are planned for next year. None of those strains are tracked either
