Every strain I have bought from dr. greenthumb has been top drawer and exactly what he says it is. I have been buying from them for over 10 years adn never have been let down yet. He has legit cuts of OG, Bubba, Chemdawg, Trainwreck, C99, Sour Deisel, U.K. Cheese and every time he comes out with one people who don't know any better start to shoot off that he doesn't have them. Then the grow journals and smoke reports get done and lo and behold all the naysayers were wrong. I know because I've grown em. If doc says it is the original G13 that Neville had years ago and lost, then I for one believe him and this plant is serious shit.
