Cosmic Cheddar F1 by Royal Queen Seeds
Cosmic Cheddar F1 by Royal Queen Seeds is a photoperiod F1 hybrid that combines modern American genetics with a flavour that takes things back in a much more old-school direction. Created from Cake Mints, Platinum GSC and Gorilla Diesel, it pairs ultra-high THC with a distinctly savoury Cheese aroma.
That’s what immediately separates Cosmic Cheddar F1 from many newer hybrids. There’s still citrus, fruit and earth in the background, but the defining feature is that unmistakably funky Cheese character.
Cosmic Cheddar F1 Genetics, Flavour & Finished Product
Royal Queen Seeds gives the genetic background as:
Cake Mints × Platinum GSC × Gorilla Diesel
It’s an interesting combination. Cake Mints and Platinum GSC bring plenty of modern American influence, while Gorilla Diesel adds another layer of potency, resin and pungent fuel character.
RQS developed these genetics through its F1 breeding programme, using carefully selected parental lines to produce a first-generation hybrid with strong uniformity and hybrid vigour.
The finished terpene profile is described as:
Cheese · Citrus · Earthy · Fruity
Cheese is the headline note, bringing a savoury, funky aroma that RQS specifically connects with legendary UK Cheese genetics. Fruit and citrus provide a brighter contrast, while earthy notes add some depth underneath.
RQS lists caryophyllene, humulene, limonene, linalool and myrcene among the major terpenes.
The finished flowers are described as dense and fist-shaped, with bright pistils and substantial resin coverage. Royal Queen Seeds describes the overall character as physically relaxing yet uplifting.
At SeedMasters.com, we think the finished profile is what really sells the genetics. There’s enough sweetness and fruit in modern cannabis already. A properly funky Cheese strain is a welcome change.
Cosmic Cheddar F1 Grow Info
Cosmic Cheddar F1 is a photoperiod F1 hybrid, rather than an autoflower.
Royal Queen Seeds lists a flowering period of approximately 50–60 days, or around 7–9 weeks, with an outdoor finishing point in early October.
Height is given at approximately 80–120 cm, while production receives an XXL rating.
RQS also highlights uniform structure, hybrid vigour and good stress tolerance as important characteristics of the F1 genetics.
THC is officially classified as ultra-high, while CBD is low. Royal Queen Seeds doesn’t attach a precise THC percentage to the current specification, so we’d stick with the breeder’s wording rather than turning “ultra-high” into an unofficial number.
For SeedMasters.com customers, all flowering, height and production information is provided as breeder-supplied reference data for comparing and identifying collectible cannabis genetics.

Our Take on Cosmic Cheddar F1
At SeedMasters.com, we’re pleased to see Cheese getting some attention again.
Cannabis genetics move in cycles, and over recent years we’ve seen huge numbers of Cookies, Gelato, Runtz, candy and tropical fruit crosses. They’re popular for good reason, but eventually something properly savoury starts sounding quite appealing.
Cosmic Cheddar F1 gives us that.
The Cake Mints × Platinum GSC × Gorilla Diesel background is thoroughly modern, yet Royal Queen Seeds has selected a finished profile that points back towards the pungent Cheese aromas that became such a big part of UK cannabis history.
We also think it’s worth looking beyond the Cheese name.
Citrus and fruit provide contrast, while earth adds some depth and prevents the profile from becoming one-dimensional. Gorilla Diesel in the genetic background also gives the family tree a suitably pungent edge.
Then there’s the F1 breeding.
Like Astro Lemonade F1, Cosmic Cheddar F1 shows Royal Queen Seeds expanding its F1 programme beyond automatic genetics and into photoperiod varieties. The result is a strain designed around uniformity and hybrid vigour without giving up the characteristics people expect from photoperiod genetics.
The ultra-high THC classification and XXL production rating will attract plenty of attention, but neither is the most memorable thing about Cosmic Cheddar F1 for us.
That would be much simpler:
It smells like Cheese.
And in a collection increasingly full of sweets and desserts, that’s enough to make Cosmic Cheddar F1 stand out.
