yeah, my limited understanding of it is that there were a bunch of guys in Amsterdam that grew and swapped genetics and maybe even worked at some of the original seed shops (Sensi Seeds, Super Sativa Seed Club, etc...). When they all broke into various new seed companies, one of them snagged the name white widow for his phenotype or hybrid. And as the story goes with the real creator moving companies, the name changed as well. I have no empirical evidence to prove the Mr. Nice variety is the original. But have read many claims as such, and never really heard it argued another way. If someone else knows more, or if I'm incorrect....please feel free to chime in here anyone! I'd love to know myself if it's the original or just a great job done by Mr. Nice marketing.
