as someone who lived all his life in southern cali and now resides in northern cali, the weed is as good quality wise in southern cali as it is in northern cali. now that theres medical marijuana shops the level of quality is equivalent all across the state.
weed is cheaper in the bay, thats about it
im almost willing to wager that the OG in southern cali (which is all people smoke in southern cali, people in norhtern cali are more open to different strains) is better than northern CA.
and they dont get it from northern cali, theres a place called San Fernando Valley that produces almost 3/4ths of the OG in So.Cali
for instance, there was a green door in southern cali, green door in northern cali. same shit
