yea the humboldt purple is very sought after, I would love to get my hands on straight purple kush, but its definitely an old timer strain. It seems like the dispensaries don't wanna purchase and stock the old strains, clones or meds. Everything is about the new hybrids and exotic flavors. I been looking for purple kush, skunk #1, Northern lights, maui wowi, and ak47 for a while, but no luck. You can get crosses of them, but not the original, at least in my experience.
I posted pics in both of my grow threads of my purple dreams outdoor if you wanna check it out. I been running it 2 years I think now and its been my most rewarding strain. SUPER easy to grow, you can't stop that lady from getting big, incredible yield, and is potent enough to knock me outta the saddle so to speak, and I have very high tolerance. Its only downside is it has a long flower time. 10 weeks is the earliest you can chop, but 12 weeks is really where you wanna cut her down. Late october finisher outdoor, last year I left a dozen up till mid November and those were top notch.
