This project arises from the breeder’s desire to put their very favourite strain, The Blues, into autoflowering format. Although little-known outside of the UK, The Blues (or Pukkas) proved a firm favourite among those who were aware of her existence. There are several versions that are clone only, and respect is due to of the hardworking guys and girls who have been working with it with much love and attention for so many years. It is a favourite with very, very good reason.

This one is a brand new cross created with two of the best varieties from the breeder’s new family of elite autoflowering strains - A Chemdogging male (Chemdawg D cut x O.S.S. Auto) and a lovely Blues Auto female (UK Blues cut x Purple Indica Auto). Both the photoperiod parents are known to be extremely smelly varieties, and this carries through to their children! Clothes pegs are advised.

After years of intense research and trials, Mephisto Genetics have released their interpretation of Chemdawg - with an automatic twist! The result is an extremely potent plant that grows medium-tall with good-sized internodes, and has a powerfully nasty chem' smell that brilliantly foreshadows the intense high. A classic in the making!

Those crafty breeders took a 24 Carat female and hit her with some jibberishly-named Hubbabubbasmelloscope male pollen. The result is a hybrid with fantastic vigour from the latter strain, which can reach heights of 120cm in restrictive pots. The buds are 24 Carat-dominant: sour, hard and dripping with resin.

Mephisto Genetics Cannabis Seeds: three people, one vison.

Mephisto Genetics is an exciting cannabis seedbank established in 2012, based in Spain. It has been working with autoflowering marijuana plants for over a decade, experimenting, breeding and developing its already extensive knowledge base. Mephisto is a small team consisting of Mitch, Tim and Szy... a combination that believes in the values of good, old-fashioned, hard work. They feel that keeping everything in-house achieves the best possible results. The team works with the very best genetics, mostly elite clone-only strains from around the world, or rarities that they use to create F2's and photoperiod parents.

Top marks in every Mephisto Genetics review.

Their varieties are not generic auto x auto strains but instead have been fully developed from non-auto to autoflowering over many generations. Mephisto Genetics refuse to take shortcuts in case the quality of the end product is compromised, an approach that has yielded some outstandingly good strains, unmatched anywhere across the market.

Fantasmo Express Automatic by Mephisto Genetics: one of the greatest strains ever produced.

This top-yielding auto is the most sativa-dominant variety in the breeder’s repertoire. Its genetics stem from the revered OG Ghost Train Haze, it grows brilliantly indoors and outside, and it produces a lively, vital and giggly buzz. It is the perfect autoflowering cannabis strain and a great introduction to a superb breeder.
