I don't know who's telling you that but they are mistaken, IMO. Dinafem power kush I had was some of the most potent bud I've done. Easily near 20% thc, and fat dense yields with quick flower time, etc...I've heard that most of the dinafem line tends to be average, other then the Blue Hash. But I tried their Shark Attack, and thought that was pretty good also. Reminded me of an old time earthy sativa... I tried Moby Dick, but I'd have to say while it smelled tremendous while flowering and yield was up there. I'd have to grade it as only average.
