i have to do some research before i say this is true. i was just told my Grand Daddy Purps is a God Bud strain. i was told the God Bud gets passed off as GDP a lot since both of there appearances look the same. plus many other characteristics of each strain are shared equally. so who knows. i guess you really can;t really on bag-seeds. either way, no matter if it is God Bud or GDP, ill be equally as happy. they are both fantastic strains in my book.
