I would have to say some phenos are more skunk spray vs dead skunk. Much of it is more sweet skunk like Sk1, but is different than Sk1. Some phenos are Pineapple.
I had more luck with Dominion Seed company. But as far as potency goes the Nature Farm gear is potent.
Dominion was one of my favorite breeders when he was around.
Dominion Seed Company had some really skunky smelling stuff, but he got busted on a non weed related charge, and is out of business. For now
I found some really skunky stuff in his Dominion Skunk, Skunkband v2, and Local Skunk. But is really more skunk spray vs dead skunk. All of it reeks, and you can smell it 50 feet away.
Headie Gardens still has some of his stuff, but is in low supply. But it is super cheap, considering most of it was $150 a pack, and is now $50 a pack. Best deal on the net IMHO.
