Double Grape Auto
Double Grape Auto is a cutting-edge F7 feminized autoflowering strain, born from the aromatic union of Sour Stomper and Grape Crinkle. This balanced 60/40 indica-sativa hybrid delivers robust trichome development and a mouthwatering grape-gas bouquet that belies its compact frame. Clocking in at nearly 37% total cannabinoids (with over 31% THC), it stakes its claim as one of the most potent autos around.
Cultivators of all skill levels will appreciate its forgiving nature—this strain flourishes with minimal fuss, responding well to gentle LST or strategic leaf-tucking. It stays petite at 22–31 inches tall over a 70–80-day cycle, making it ideal for tight spaces or Sea Of Green setups. Indoor growers should monitor odor, as its sweet-sour grape funk can become pronounced. Yields range from 90 to 120 grams per plant, reaching up to 500 grams per square meter under a 600-watt light.
The dense buds glisten with a frosty layer of resin, exuding flavors of ripe red grapes and fizzy soda on the exhale. Users report an initial cerebral uplift that melts into soothing sedation, perfect for easing aches, boosting appetite, or drifting off to sleep. High terpene levels, particularly myrcene and limonene, and resin production make it a stellar choice for extraction projects.

Sour Stomper Auto
Sour Stomper Auto is an F7 feminized automatic with equal parts indica and sativa, crafted from GrapeStomper OG and Sour Crack, undergoing careful selection by Mephisto Genetics. Its hallmark is a vivid red-grape aroma intertwined with a tangy, meaty edge that teases the palate. This balanced hybrid promises euphoric, mood-lifting highs, grade A bag appeal, and pronounced terpenes, flourishing equally well indoors, outdoors, and in greenhouses.
Growing from sprout to harvest in just 65–75 days, it matures into a bushy 20–28 in. specimen that rewards growers with 120–150 g/plant. At the start of Sour Stomper’s life, it grows squat and dense like an indica, but once flowering kicks in, it unveils its OG lineage with a remarkable stretch, becoming up to four times taller. This stretch can be harnessed through SCRoG or simple defoliation to maximize light exposure and airflow. Be prepared for a potent fragrance, as its high odor profile demands proactive ventilation.
Finished colas shimmer with a heavy dusting of crystal, releasing pine-lemon and grape-driven terpenes at every twist of the jar. Its buds are incredibly resinous, needing little to no trimming. The effect is uplifting and sociable, easing stress and brightening spirits while delivering a gentle body relaxation. Sour Stomper’s exceptional resin yield makes it an excellent candidate for concentrates and solventless extracts.

With medium odor intensity, a carbon filter will suffice to keep smells in check. Given proper care, this strain yields an impressive 100–150 g/plant of vibrant lime-hued buds.

Starting as a light-hearted challenge between Mitch and Tim to innovate consistently exceptional autoflower strains in 2007, Mephisto Genetics has come a long way. Their journey saw them establishing a farm located in the mountainous Spanish countryside in 2012. Later on in 2017, they set up a US distribution hub to cater to their biggest customer base. They upgraded to a larger facility in Spain in 2020, albeit with operations halted due to Covid-19 travel restrictions.
Now back at full speed, they’ve resumed production for existing strains, with a slew of new ones nearing release. Mephisto upholds its renown as a premium feminized autoflower seed breeder by adhering strictly to trademark standards of quality.
Awards and accolades have followed suit, with Mephisto claiming the revered Best Breeder title at the 2023 Autoflower World Cup and the recent Spannabis fair, Europe’s largest cannabis expo. Closer home, they also scooped up the Best Breeder recognition at the 2023 American Autoflower Cup held in Los Angeles, CA.
This Double Grape is so dang close. Hopefully this'll be the last feeding.

But these awards are second-hand joy for Mitch and Tim, who find greatest pride in their well-rounded body of breeding work and the organic global community of fans and growers supporting them.
Hailing from a spanking new hub in Barcelona, Spain, Mephisto Genetics strains are carefully developed, tested, and stabilized over nearly two years. Once the team confers approval on particularly stellar strain traits, commercial runs of seeds are conducted with a reputable producer in either the US or Canada—markets with significant traction for this powerful breed.
In the US, the highly anticipated release of these new feminized autoflower seeds takes place bi-weekly on the Mephisto website, stirring excitement among the growing autoflowering community. Rewarding these loyal brand fans, Mephisto has launched the “Piggy Points” program. Additionally, respectably recognized seedbanks like Seedsman keep a steady supply of Mephisto’s feminized autoflower seeds.

Currently, distribution centers and grow hubs sprawl across multiple countries and continents, ensuring the swift delivery of seeds. In fact, the vast majority of all Mephisto seed sales take place in the US, which stands testament to both the popularity of autoflowers and the indomitable brand reputation in America.
Mephisto Genetics shows no signs of slowing down, with numerous strain projects slated for resumption that will hit their website upon final rounds of testing and runtime completion. Among these highly anticipated releases, expect unique Gelato crosses featuring different dessert strain phenotypes, legendary genetics including a 30+ year-old cut of old school haze for lovers of robust sativa effects, and more CBD-rich strains as Mephisto continues its exploration with this intriguing cannabinoid. No doubt, exciting times lie ahead for seed collectors and growers!
