Yeah man, if I'm not mistaken (could very well be), the Alien in the Alien Blues is Alien Tech x Tahoe OG. Alien Tech was a land-race Afghani brought over to the states by a soldier who I believe is Obsol33t of Franchise Genetics. I think I just had the luck of an atavistic Afghan pheno, I was pleasantly surprised! It seems like everything grows like an OG nowadays.
Then again, DNA has that Martian Mean Green, that has nothing to do with a land-race, and I've heard crosses with that being referred to as "Alien xyz". Biology always pissed me off with it's lack of persistent nomenclature, cannabis isn't even the worst culprit. Do some work with master regulatory genes, hox genes, desert hedgehogs, sonic hedgehogs, robotnikin re-uptake inhibitors, all pure fucking nonsense made up on the spot by the guys that discovered them. This is why I chemistry.
