Ok so this along with the other 136 pages of rules and a $4000.00 per year license fee is why there are no good seed banks in California and likely never will be:
§ 5408. Sale of Live Plants and Seeds (a) A licensed retailer shall only sell live, immature cannabis plants and cannabis seeds if all of the following requirements are met: (1) The plant is not flowering; (2) The plant or seed originated from a nursery that holds a valid license from the Department of Food and Agriculture or a licensed microbusiness; and (3) A label is affixed to the plant or package containing any seeds which states “This product has not been tested pursuant to the Medicinal and Adult-Use Cannabis Regulation and Safety Act.” (b) A licensed retailer may not sell any other live plants. (c) A licensed retailer shall not apply nor use any pesticide, nor cause any pesticide to be applied nor used, on live plants. Authority: Section 26013, Business and Professions Code. Reference: Sections 26070 and 26100, Business and Professions Code
How can you ever duplicate all of the genetics out there - California does it again - although it is a couple of steps ahead of the Feds.
