NHPR, if they have any (check their website menu). They didn't have any clones out 10 or so days ago. While their clones usually don't look the best, they almost always seem to grow great. The best and widest selection is found at Elemental Wellness, check their website and menu. Top strains offered from top nurseries. They almost always have at least a dozen strains of clones available. Always healthy looking and I've had good luck with 3 different buys (18 plants).
In Oakland, you have Harborside Health Center, also the real deal. I don't believe they display clones in their online menu. And of course you must have your prescription and CADL to enter any of these establishments.
Hope this helps, and good luck
