A new Antonio x Dutch Passion collab

Antonio’s rigorous pheno-hunting and lab-backed approach guarantee consistency, with Slush Mint Cake already capturing the 2025 Highlife Cup’s “Mostly Indica” category. 

Known for previous hits like Sherbelato Cake and Ice Cream Haze, the Dutch Passion x Antonio collaboration continues to push boundaries, crafting strains that balance potency, flavour, and growability. 

If you’re eager to explore new cannabis genetics that offer true boutique quality, Slush Mint Cake showcases expertly crafted genetics with bold, terpene-rich flavours and a potent THC punch exceeding 25% and coming close to the 30% mark.

Antonio shared his thoughts on the breeding project:

 “Crafting Slush Mint Cake was a labour of love, blending the finest Slurmint and Ice Cream Cake genetics from my collection. Years of pheno-hunting & rigorous testing paid off with a strain that’s bursting with character - creamy, gassy & fruity terpenes and a rock-solid 25%+ THC punch—perfect for growers chasing elite quality and consistency.”

The breeding process: from concept to cultivar

The creation of Slush Mint Cake began with a bold vision: to craft a strain with elite potency, unique terpenes and grower-friendly traits. 

Dutch Passion once again joined forces with Antonio, one of Europe’s most successful breeders who has collected one of the best independent mother/genetics collections after decades of growing & trading genetics with other multi-cannabis cup winners. These genetics were pushed to their max to create Slush Mint Cake.

Antonio explained more about his team-up with Dutch Passion: “Partnering with Dutch Passion gave me the platform to push boundaries. Slush Mint Cake is a testament to relentless selection and testing - delivering dense, frosty buds with a terpene profile that sings and a powerful high that hits all the right notes for growers and connoisseurs alike.”

Antonio & Dutch Passion aimed to merge Slurmint’s intense candy-gas profile with Ice Cream Cake’s popular creamy, sweet potent allure. These are two of Antonio’s most stable and predictable high-THC bangers - among his personal favourites.

Selecting the perfect Slurmint mother and Ice Cream Cake father involved years of pheno-hunting, with Antonio testing dozens of plants for stability whilst ensuring THC levels would top 25%. 

The Slurmint mother was found following a pheno-hunt after a large grow of Slurmint IX seeds. Slurmint is a cross between a cup winning Slurricane and a special Platinum Kush Mints. The Slurricane (known to some breeders as ‘Purple Punch x Do-si-dos’) is a potent, compact USA strain praised for her exceptional buds and bag appeal. 

The main challenges included balancing terpene complexity with yield consistency, but breakthroughs came through rigorous lab testing, revealing phenotypes with up to 33.28% total cannabinoids. 

“I wanted a strain that screams loud cali-weed flavour but hits like a freight train” Antonio explained. “The Slurmint x Ice Cream Cake cross was a puzzle at first - finding that sweet spot with the right phenotypes took patience.” 

Backed by Dutch Passion’s infrastructure, this meticulous pheno-hunt & subsequent breeding process birthed a Highlife Cup-winning cultivar ready to shine for connoisseur growers seeking high-grade stash.

Lab testing has shown some phenotypes can hit nearer 30% THC, with 33-35%+ total cannabinoids for a powerful entourage effect. 

The terpene profile dazzles with candy, creamy vanilla, sour fruit and forest berry notes. This is  driven by high levels of limonene, linalool, and myrcene - for delicious vaping and exceptional concentrates.

Grower tips and recommendations

Slush Mint Cake, an indica-dominant feminised seed hybrid from Dutch Passion and breeder Antonio, is a rewarding choice for growers aiming for premium quality buds. This Highlife Cup winner blends Slurmint IX and Ice Cream Cake, yielding heavily indoors. Outdoors in sunny, dry bloom conditions she can produce up to 1kg / 2lbs per plant. 

The brisk 8–9-week flowering period suits various setups, she thrives in SCROG, LST, or HST environments thanks to her moderate stretch. The notably long-leaf stems (or ‘petioles’), a particular genetic feature of Slush Mint Cake, enhance airflow and light penetration. Indoors, netting (or similar) is useful to support the dense, resin-coated buds. 

Ideally maintain 40–50% humidity in later bloom to prevent mould in the compact, frosty flowers. The buds/blooms are easy to trim and ideal for quality-focused growers who love dense trichome frosting. 

Hash makers have reported that the extra-long trichome stalks make this a particularly good strain for washing & extractions, with higher-than-average concentrate yields.

Outdoors, large grow containers in warm climates maximise yields, but greenhouses are recommended in wetter regions with temperate or damp fall/autumn climates. With 25%+ THC levels and pungent terpene-dripping buds, Slush Mint Cake delivers creamy, fruity flavours and an exceptionally powerful, euphoric high. 

Supported by consistent lab results and coming with the reassurance of a Highlife Cup Top Prize, Slush Mint Cake is a dependable, high-quality strain for both personal and commercial growers.
