The latest limited-edition release from Karma Genetics has landed at Pure Sativa, bringing together four elite cultivars bred for loud terpene expression, serious resin production, and classic Sour / OG power.
This drop includes three feminised strains and one regular release, all produced in extremely limited numbers. With a strong emphasis on WPFF (Whole Plant Fresh Frozen) performance, hash washing potential, and Karma’s signature gassy, sour OG backbone, this collection has something for everyone, whether you're a true Sour-OG connoisseur, an extractor, or a collector.
Feminised Seeds
Tahoe Banger (Tahoe OG × Headbanger)
Cheddar Blossom (Cheese × Sunset Sherbet) × Fresca Melon
Nectar (Honey Fresca × Fresca Melon)
Regular Seeds
Sour Hayabusa (Hayabusa OG × KG Sour Diesel Bx2)
Each strain reflects Karma Genetics’ continued focus on elite breeding, proven parents, and modern extraction-ready cultivars.
Tahoe OG × Headbanger

Tahoe Banger is the latest evolution in Karma Genetics’ legendary Headbanger lineage. Headbanger is widely regarded as one of Karma’s most iconic creations — a Sour OG-style hybrid that captures the power and flavour of classic Sour Diesel and OG Kush, while offering a more manageable growing experience.
By pairing Tahoe OG with Headbanger, Tahoe Banger reinforces everything Karma is known for:
Bright green buds
Aggressive sour fuel terpenes
Classic OG gas and sharp citrus
This strain delivers a potent, no-nonsense Sour OG hybrid, staying true to the award-winning profile that built Karma Genetics’ reputation. Expect a cultivar that performs well indoors and out, with strong structure, high resin output, and unmistakable old-school flavour.
Why choose Tahoe Banger?
Elite Sour OG heritage
Gassy, fuel-forward terpene profile
Easier to grow than traditional Sour or OG lines
Limited-edition feminised release

(Cheese × Sunset Sherbet) × Fresca Melon
Cheddar Blossom is a purpose-built WPFF cultivar, bred with a clear focus on hash washing performance and loud terpene output. Karma Genetics selected a Cheese × Sunset Sherbet mother and pollinated her with the elite Fresca Melon, one of the most respected hash-washing cultivars in modern breeding.
While Cheese and Sunset Sherbet are not traditionally known as top-tier washers, Fresca Melon brings elite resin production, strong trichome structure, and explosive pineapple-leaning funk. The result is a strain that merges:
The funky, savoury depth of Cheese
The sweet, creamy notes of Sherbet
The pineapple funk, resin density, and washability of Fresca Melon
Cheddar Blossom is expected to deliver excellent WPFF returns, making it a serious contender for extractors chasing flavour-heavy bubble hash and rosin.
Why choose Cheddar Blossom?
Designed specifically for WPFF extraction
Loud, complex terpene profile
Elite hash-washing genetics
Extremely limited feminised release
Honey Fresca × Fresca Melon
Nectar is another hash-focused powerhouse, engineered to deliver exceptional resin yields and exotic terpene profiles for WPFF and bubble hash production.
The Honey Fresca parent (Honey Banana × Fresca Melon) brings:
Rich honey sweetness
Ripe banana cream
Tropical fruit undertones
When crossed again with Fresca Melon, Nectar doubles down on what matters most to extractors:
Heavy resin coverage
Strong trichome integrity
Loud, mouth-watering terpene expression
Both parents are known “loud washers”, meaning Nectar is expected to produce excellent bubble hash returns with an intensely tropical, sweet, pineapple-forward aroma.
Flowering time: 8–9 weeks
Yields: Medium to high
Edition: Limited feminised release
Why choose Nectar?
Built specifically for WPFF extraction
Tropical, honey-banana terpene profile
Excellent hash returns
Short flowering time
Hayabusa OG × KG Sour Diesel Bx2
Sour Hayabusa represents the kind of elite Sour OG breeding that made Karma Genetics famous. This regular release pairs the formidable Hayabusa OG with Karma’s infamous KG Sour Diesel Bx2 stud — a cornerstone male used across some of his most respected work.
Hayabusa OG is a top-tier OG Kush hybrid, selected as a mainstay within Karma’s OG lineup. Its genetics include:
Race Fuel OG (High Octane OG × Face Off OG Bx1)
Biker Kush (Karma Genetics)
This creates an OG with serious fuel, flavour, and potency, perfectly suited to pairing with the sharp, sour aggression of KG Sour Diesel Bx2.
The result is a true powerhouse hybrid, blending:
Deep OG Kush gas
Sharp Sour Diesel funk
High potency and strong structure
Flowering time: 9–11 weeks
Yields: Medium to high
Format: Limited-edition regular seeds
Why choose Sour Hayabusa?
Elite OG Kush × Sour Diesel genetics
Perfect for breeders and pheno hunters
Old-school gas and sour flavour
