I can't offer anything on each strain individually but i can on k2 from barney's, a cross of what is supposed to be the original white widow and northern lights. It's a tough sob, very impressive plant that can yield very impressively when pushed just right, i have seen a talented grower pull minimum 3pounds per plant, one 600 hps to plant. The stretch in flower is intense but it all fills out. The smoke is top notch, smooth and tasty and it's one of those strains you can really influence the high come harvest time for indica/sativa effects. For a good producing and all around strain i highly rep it
