Mephisto Limited Editions Automatics

Mephisto Limited Editions are one off combinations of any two strains within the current catalog and collections. These are special pairings that we plan in advance that we think we be highly complimentary to each other. We aim to produce enough stock to have the limited edition available for one year, but they can sell out much sooner!
These are firm favorites among our Mephisto clientele, once they’re sold out they’re sold out so grab a pack whilst you can!
