I grew out the Godfather Kush and thought it was fuckin awesome, I haven't tried the Godfather Purps but I am also not really a fan of most purple strains. I am growing some purple strains by DVG but that is because I like to have at least one purple strain and if I can find one that is better than the cookies cut than I will be more than happy. I am not the biggest fan of growing cookies as it is done by everyone, same as growing blue dream, so anyways I would do what your heart tells you.
I enjoyed my time with MTG seeds but I just didn't seem to go back for any other packs and I think that is because I wasn't getting any deals when buying their gear where as there was all kinds of other deals going on for the other companies I bought. That was back when the tude accepted mastercard.
