Genetic Heritage High School Sweetheart [Gage Green Genetics] x Sour Stomper Seed Type F5 Feminised Automatic Indica/Sativa 55/45 Cycle Time 75 to 85 days from sprout Size 80 to 110 cm Yield 80 to 100 grams. Aroma and Flavour Juicy, bursting with fruit and sweetness. Cherry forward with sour elements. Sweet smoky BBQ added into the mix. Floral on the body with a creamy, vanilla finish. Flavour Keywords Fruity, Citrusy, Floral, and Sweet Effect Mellow and mood-enhancing relaxation that is cerebral and calming, but not sedative. Grow Difficulty Intermediate Growth Odour High We’ve always had a soft spot for the incredible work done by Gage Green Group (GGG). Whether you’re a Meph Head new or old, you’ll know all about our legendary Sour Stomper—born from a killer selection of GGG’s Grape Stomper OG crossed to our own Sour Crack. It debuted as part of our first-ever Artisanal Automatics release back in 2016, quickly became a fan favourite, and has been a staple in countless limited-edition drops. To this day, it’s still on a lot of Meph Heads’ wish lists for good reason—it’s that damn good. When the chance came to give a proper nod to both Sour Stomper and the legends at GGG, we didn’t hesitate. Our vision was clear, take an already sought-after, highly regarded elite photoperiod and push it to the next level. We first acquired our High School Sweetheart seed stock in 2018. The F0 run took place in 2019, followed by the F1 run in 2021. During each selection, we prioritised extreme frost levels, ensuring the resin production was second to none. Bud structure was another key factor, allowing us to retain the distinct growth profile of the photoperiod parent while adapting it into an auto form. We also worked to bring forward a unique and standout flavour that would make this strain instantly recognisable. The decision to pair Sour Stomper with High School Sweetheart wasn’t just about lineage—it was about legacy. With GGG at the heart of both parent strains, this project felt like the perfect way to honour some of the finest photoperiod genetics in the game. Schoolyard Crush is a pleasure to grow, showing exceptional uniformity and consistency even from the early generations. When it comes to the smoke, it’s rich, flavourful, and truly something special. This one has quickly become one of Tim’s personal favourites, and after all the work put into it, we can confidently say it’s one of the highlights of our last few years of releases.
