Do a search for instagram "farmers market" style meet ups. Its a new thing that many have been doing for a few years.. you get added to a list, of approved patients and they text out the address.
Its like a circus of growers and sellers. You can get anything at the good ones. Im in N. Cali now, but I know L.A. had them all the time. Its just a lot of searching and leg work to find them, get added and find the damned place.
Once you do though.. the prices and the quality will shock you away from dispensaries forever.
