Sour Stomper is the first Mephisto variety whereby someone else had a hand in the project, and we’ve been delighted with the results at every stage since. So first and foremost we have to give credit to GBD @Autoflower Network for having the foresight, skill and taste in quality genetics to get this project underway. He made the F1 cross using a Sour Crack female and Grape Stomper OG male, so here’s a word from the man himself: “Sour Stomper began with a trip to Denver, Colorado to celebrate the legalization of recreational cannabis use on January 1, 2014. After spending two weeks sampling almost one hundred strains there was a clear standout: Grape Stomper. The grape flavors she emits are other-worldly, almost too good to be true! This began the quest to find Grape Stomper genetics and introduce them into the already unbelievably good autoflower genetics created by Mitch and Tim. The search was damn near impossible, taking correspondence relay races, waiting lists, and some asking extra nicely to finally acquire the beans. If anyone goes on a successful quest for them today my hat is definitely off to you! Once in hand they were immediately germinated, vegged, cloned and flowered. All of the females were absolute crystal queens, but they all left something to be desired in the way of grapey goodness, however, one of the males was a different story. The scent from his tacky stems transported me right back to the flavors of the original Grape Stomper, with a little something extra, slightly offensive in the mix. He was selected to pollinate a super sweet Sour Crack that had strong grape undertones and was caked in resin. From there the offspring were handed off to Mitch and Tim to work their magic on, and to translate the best qualities of Grape Stomper into autoflower format. After seeing the Sour Stomper F3 grown out first hand in Spain last year I can safely say the quest was a complete success.” On receiving the F1 seeds from GBD, we set about our usual process for F1 runs, starting 30-40 plants, narrowing down to a selection of 9 females. During the F1s we witnessed some of the most complete, thickest trichome coverage we’ve had the pleasure of seeing, out of anything, automatic or photoperiod, ever. We selected two pollination candidates, a thick Sour Crack dominant lady; big, thick, fingered leaves, fantastic resin, with an added injection of a sweet grape scent. The second, a Grape Stomper OG dominant lady with nice branching and more elongated colas. She had thinner leaflets, a positively intoxicating smell and again covered in whiteness. The F1 grow was in winter 2014 and the plants quickly turned a deep exotic velvet purple to black with the cooler temperatures. Generally, we like to steer away from the plants at F1 that favour the auto parentage, but with this variety and the other Artisanals so far, the already high-quality building blocks used to donate the auto trait is making this decision trickier, but we opted to go with the Grape Stomper leaning parent. Actually, in hindsight, I don’t think we could have gone far wrong with any of the selections from this cross at F1. The foliage of these F1 females were so triched out, it almost felt like sacrilege to trim them. At F2, we witnessed a more compact version of the F1s, but a larger version of the Sour Crack, one of our strains we’ve grown and played with relentlessly over the years.
