I can only go by my experiences, I was a 1970’s Humboldt grower, I remember when skunk was developed in the early-mid 70’s about the same time as sinsemilla and Indica, it was an Indica/sativa cross. It took over immediately, guys were getting 5k/lb (in the 70’s) for top shelf skunk. I have searched and probably bought 6-7 different current strains that claim to be “skunk”, well they are all weak sauce at best. Nothing like the old school skunk. The old skunk was so potent you could smell it in a car in the driveway, when cruising the back roads in fall, you could smell it for miles! I’ve made several trips to my old stomping grounds, and contacted all my old contacts (that are still alive)l, hit up every dispensary in the county (and there’s a LOT of them), and I can sadly say “The skunk is dead!” I can also say that back then there were few recognized strains, skunk was skunk, when people say it was a cross of this strain and that strain, that’s not correct, because those strains didn’t exist in the 70’s. In fact those later crosses were the death knell of skunk, they might of gotten higher THC levels (though at the time skunk THC levels were among the highest), but they bred out the terpenes for skunk!
