Auto Double Grape is the F3 version of the original limited edition Double Grape auto-flowering strain. Auto Double Grape is a cross of Sour Stomper x Grape Crinkle and the extra two generations of highly selective breeding have concentrated the special attributes of this strain further bringing vast trichome coverage, delicious flavour and huge potency to the table.

Auto Double Grape is 60% indica and 40% sativa; it is the product of the union of two great Artisanal Mephisto strains - Sour Stomper (Sour Crack - Grape Pheno x Grape Stomper OG) and Grape Crinkle (Canadian Crinkle x Supernatural x Ripley's OG) - and hybrid vigour is definitely the watchword here. This plants grows with quite an open structure but becomes bushy, a quality which can be enhanced by judicious leaf-tucking. Double Grape also responds well to Low Stress Training (LST) if done early enough in the life cycle. Odour control is a must with this plant if growing indoors!

As you would expect it remains a short-ish plant growing to a height of 55 - 80 cm. tall and approximately 40 - 50 cm. wide. Grown as single plants growers can expect to yield 90 - 120 gr/plant but Mephisto recommends planting 9 to a 600 watt grow light indoors (1.2m2) in 12 litre pots where the yield can reach 500 mgr/m2. This strain will also thrive in a greenhouse environment but proper outdoor cultivation is best reserved for regions with warm climates. The life-cycle is in the region 65 - 70 days which is certainly not too long to wait for a plant of this quality.

In terms of flavour grape's certainly the name of the game including ripe red grape fruit flavours and also an artificial fizzy grape drink taste. THC production has been measured by CANNA at 21.78%! The effect is very stimulating initially evolving into a more relaxed, sedative type of stone. Therapeutic uses include appetite stimulation, relief from aches and pains and insomnia.

Auto Double Grape produces enormous quantities of resin and makes fantastic bubble hash and other extracts including rosin.

About Mephisto Genetics

View all Mephisto Genetics products

The idea or dream of Mephisto Genetics was conceived during a typical rainy ‘summer’ in England many years ago now. Two breeders, now business partners were in somewhat of a grow-off, working with equally small spaces but in competition of who could produce the best yield in the quickest time. While both breeders were growing incredible amounts of plants, neither were impressed by the effect and potency of their autoflowering varieties. It was then that a new gauntlet was laid down and the idea of Mephisto born. It was an idea neither breeder could resist and so they moved countries and their adventure really began.

The initial aim of Mephisto Genetics was simply to create and develop, unique, high potency, high quality, auto strains developed from sought after photoperiod varieties from start to finish…and this aim has never wavered.

The difference between Mephisto seeds and other companies, is that unlike a lot of brands in the market, they don’t buy in seeds and do a quick re-branding exercise.

The seeds Mephisto Genetics advertise are the ones their customers receive. They are involved in every aspect of cultivation from selection, pollination and de-seeding to sorting and packaging.

At most, two pairs of hands touch Mephisto Genetics products before it reaches our customers. They do things on a small scale, but do things properly and with love. Mephisto also actively invite their fans and customers to follow our work that we document. The list of companies where the consumer can talk directly with the breeder is limited, and Mephisto’s openness and friendliness coupled with the great reviews of their seeds and varieties makes it a no brainer for people to give them a try.

If you want your hard earned money to go to hard working breeders that have shed blood, sweat and tears into creating a special product for you, look no further than Mephisto Genetics.
