Mephisto Artisanal Automatics

The pinnacle of Mephisto’s breeding work and autos today. Introduced in April of 2016, Initially only for direct sales only, DC Seed Exchange is now able to extend these amazing genetics to our customers. The Artisanal Automatics are projects derived from using our solid Mephisto originals line outcrossed to new photoperiods of amazing quality and once more worked over 4-5 generations and a time period typically over 2 years until they are fully automatic again. These are the newest developments in the mephisto HQ and we truly see these strains as the pinnacle of auto-flowers in the world today. The artisanales are only made using the very best selections possible with zero compromise, as a consequence the prices are higher than our other lines but still reasonable considering the further increased levels of quality.
