Mephisto Genetics is an autoflower-only breeder founded in 2012 by a small team of British growers, now based in Spain, and is widely regarded as the house that made autoflowers worth taking seriously. Lines such as Double Grape, 3 Bears OG and Sour Crack are bred over many generations for stability and potency rather than speed alone, and releases are often small-batch and sell out.
