Spent the weekend catching up on a few podcasts .. so here's some cool info on Chem from what I've learnt over the passed few days .. The skunk va 91 is the real deal one. The Joe Brand 91 bodhi pointed out is different and Good Ole Dog and Nspecta said different too. Bodhi now clarifies in his lineage if its 91jb or skunk va 91. Chem b if I remember correct became Chem sis and D was the closest rep to the va 91 but again the guys in the know said either s1 or hybrid. Again with 1-4. Number 4 being the closest rep to the va 91 but again all agreed not sister batch. Chem 1 is a more sativa leaning pheno and was mistakenly given out by nspecta as the 2 cut but when the guys grew em.out they all turned out to be the 1. Chem 2 is officially gone and 1,3 and 4 are still around. The 3 cut is not as popular as the 4 but seen some amazing pics of it. Hope this is helpful ..
