Looks kinda like a very sativa dom pheno I saw 2 years ago in my garden. Took a really long time to finish, and I dont think it fully matured by the time I had to chop it. It was a hell of a producer for being so fluffy tho, so hopefully you got something similar there.
I agree with dickcorn, I dont remember it being as potent as the indica phenos of AK, which were just knock-you-out, this was just a plain, every day smoke. Flavor to best of my memory was sweet and maybe a little fruity, kinda spicy too. Lets us know how it turns out!
You lucked out. Never seen nothing like that in a serious AK pack. Whatever that is, it is deep in the lineage. It looks like some one put 1 nevilles haze bean in your pack of AK.
