I have grown a lot of both TH Seeds and DNA genetics. A lot. There are plenty of very solid plants coming from TH Seeds, but as far as straight up fire, not really. DNA has some straight up fire ass plants, but sometimes it might be 1 out of 3 that is fire and the other 2 are OK.. But even their OK is almost as good as TH Seeds "good". Usually (at Attitudes) the DNA promotions include the "DNA Family" which is crocket farms and Reserva Privada. I would pass on RP, but Crocket Farms has some really nice strains. DNA's Holy Grail Kush has been consistent fire for me, decent size and good bud.
