I have lived in so cal all my life and I am an established MMJ vendor, clones and flowers. Anyhow, you will not find much worth mentioning in OC or LBC. The Dana Point collective (close to killer dana surf shop) is probably your best source quality bud. The staff are cocks but what can ya do.

My advice to you is make once a month trips to the valley and to reseda. Reseda Discount Caregivers has honestly 40+ strains on their menu and all are at least a 7/10 smoke and nothing is over 55/eighth. There are a LOT of clubs that are hit or miss with some 9/10 and 10/10 bud. The clubs are prices only. Its the vendors you want to follow for ultimate potency.

As I tell everyone, Growing your own is the cheapest way to keep your favorite strain(s) on hand. You could easily grow a qp every 2 months for an investment equal to the cost of a single zip and just buy clones once in a while.
