I think Str8 said it before, the smoke should be a neon blue color... and out of 12 strains going at the same time, I can still pick out GG4 even while pulled early everytime, blindfolded... after passing it out, I've seen it now looking all sorts of ways. But I'm with Dans, seems doubtful you got it...
