Well theres a thing. I have this text saved in my note pad ill paste it and see what it says lmao.
Headband
The genetics are from a bunch of guys originally from Hollywood who came over to the Dam and started what you may know as DNA genetics. They were experimenting with Headband and it was the first time I had seen it anywhere (it was like 50% more than any other bud = -€18/gram) As you know DNA carried (past tense - due to grow rooms being busted I believe) OG Kush and also East Coast Sour Diesel. These two were crossed and I believe it produced Headband 707 (i think that is what this variety is called State side) The first and only bag I bought had about 10 seeds in it. As Hayduke says, these girls have a tendency to self produce and I have had the resulting seeds from the various grows. I can tell you, the seeds produce the same plants as the original.
So that's it, I hope you are satisfied with the explanation, there is nothing more to it, it's as simple as that.
The Headband that came Third in the recent Cannabis cup is from the same strain of genetics I believe.
Back to Don's Q and Westy's response, which I think pretty much answers it anyway. You seem to either get OG Kush lookers, or Sour Diesel lookers. Thelma is almost identical in structure to the Casey Jones (which also looks very SD) Then if you look at the two I have in my veg tent, they look more indica based (which is how Louise looked before the chop) I actually love both the pheno's you tend to get, and the buds they produce also look different as well...flavour again leans towards how they look (i.e OGK - dark green leaves or SD - slightly lighter green) The only thing that seems to be eradicated from the OGK in the HB is the phenomenal stretching.
i have a bunch of hermi seeds of headband and this is one of them.
