Slurricane
Breeder: In House Genetics
Slurricane is In House Genetics' most iconic creation—a Do-Si-Dos x Purple Punch cross that helped define the modern dessert-terpene, high-resin exotic category. With deep violet-to-near-black coloration inherited from its Purple Punch parent, a creamy grape-berry-OG terpene profile, and heavy indica sedation, it has become one of the most influential boutique strains of the past decade. SeedFinder catalogs 138 direct descendants, and the #7 phenotype is widely regarded as the definitive expression of the strain. Slurricane is one of In House Genetics' most iconic creations and has become foundational breeding stock for an entire generation of exotic hash strains. Its balance of resin production, flavor, and visual appeal makes it equally valued for premium flower production, solventless extraction, and as a parent in breeding programs.
Lineage & Genetics
Cross: Do-Si-Dos x Purple Punch
Do-Si-Dos (OGKB x Face Off OG BX1, Archive Seed Bank) contributes the cookie-gas terpene base, potency, dense bud structure, and the OG backbone. Purple Punch (Larry OG x Granddaddy Purple) contributes the grape candy sweetness, deep purple anthocyanin coloration, berry cream terpenes, and additional sedative body effects from the GDP lineage.
Terpene Profile
Caryophyllene — Dominant; provides the peppery, spicy backbone from the Do-Si-Dos side
Myrcene — Co-dominant; drives herbal earthiness and the heavy body sedation
Limonene — Citrus lift in the top notes, balancing the heavy indica base
Linalool — Floral/lavender notes especially pronounced in the #7 phenotype
Humulene — Earthy, woody supporting role
Aroma: Creamy OG and tropical blueberries dominate, layered with grape candy, berry compote, peppery spice, and a gassy Do-Si-Dos undertone. The #7 phenotype is particularly loud with heavy grape-cream notes.
Flavor: Grape and berry cream on the inhale with tropical blueberry sweetness. Exhale brings earthy OG undertones, spice, and a dessert-like finish. Smooth and full-bodied.
Effects & Experience
Onset: Slow-building; euphoria creeps in over 5-10 minutes before the body stone sets in
Deep full-body relaxation and couch-lock with a euphoric mental uplift. Appetite stimulation is strong. The indica sedation builds progressively—starts social and warm, ends deeply relaxed and sleepy. Best suited for evening and nighttime use.
Duration: 2-3+ hours of heavy sedation
Commonly Reported Uses
Grower's Notes
Slurricane is an indica-dominant powerhouse from In House Genetics that has earned legendary status in the hash-making community for its consistent resin production, dense flower structure, and exceptional extract potential. The plant develops a robust, vigorous structure with strong lateral branches and medium internodal distance. Expect moderate stretch in early bloom — roughly 1.5x from flip — requiring support as heavy colas develop on lateral arms. The natural branching habit responds exceptionally well to topping, SCROG, and LST techniques for maximizing canopy coverage in limited space.
Flowering Time and Harvest
Flowering time is 8-10 weeks, with most phenotypes finishing in the 9-10 week range for optimal trichome maturity. The bud development timeline shows early stacking at weeks 2-3, rapid density increase at weeks 4-6, and a final frost-and-color push in weeks 7-9. Trichome coverage becomes visibly heavy by week 5 and continues building through harvest, creating an almost frozen appearance on mature flowers.
Nutrient requirements
Slurricane is a moderate feeder that benefits from a balanced bloom regimen. Target EC of 1.0-1.2 during early flower transition, ramping to 1.4-1.8 during peak bloom (weeks 4-6), then tapering to 1.0-1.2 before a 10-14 day flush. In soil, maintain pH 6.0-6.5; coco/hydro at 5.8-6.2. Push PK during mid-flower for maximum resin development. Cal-Mag supplementation is standard under LED. Avoid overfeeding nitrogen in late flower — the strain expresses best color and terpene profiles when allowed to fade naturally in the final 2-3 weeks.
Environment
daytime temps 72-78°F (22-26°C) with nighttime drops to 65-68°F to encourage purple color expression. Humidity control is critical given the exceptional bud density — target 55-65% in veg, 45-50% in early flower, and 35-45% in late flower. Insufficient airflow through dense canopies will invite botrytis; run oscillating fans at canopy level and defoliate strategically at flip and day 21. VPD targets: 1.0-1.2 kPa in early flower, 1.2-1.5 kPa in late flower.
Light
full-spectrum LED recommended for terpene and resin expression. Target 600-800 PPFD early flower, scaling to 900-1100 PPFD during peak bloom with CO2 supplementation (1000-1400 ppm). DLI of 35-45 mol/m²/day in flower optimizes trichome production. The strain's resin production is directly correlated with light intensity — higher PPFD within tolerance produces measurably frostier flower.
Yield
450-550 g/m² indoors under optimized conditions. Outdoors, yields range from 200-350 g/plant in temperate climates to 800g per plant in warm, sunny environments with extended growing seasons. Harvest arrives around late September to mid-October outdoors. Indoor yield per square foot is approximately 1.6-1.9 oz/ft².
Bud Structure and Trichomes
Bud structure is extremely dense, compact, and rock-hard when dried — covered in a thick, glittering layer of trichomes with colors ranging from lime green to deep violet depending on phenotype and night temperatures. The strain produces dense, photogenic flowers ideal for boutique markets and premium bag appeal. Dominant terpenes are caryophyllene, limonene, and myrcene, delivering a sweet berry-grape flavor with earthy, citrus undertones.
Wash data
Slurricane is widely recognized as one of the best "washer" strains in modern cannabis. Fresh-frozen material yields exceptional bubble hash returns, typically in the 4-6% range for quality 73-120 micron full-melt heads. The high trichome-to-plant-material ratio makes it a favorite for commercial solventless operations producing cold-cured live hash rosin. Multiple commercial rosin brands specifically cultivate Slurricane for its reliable extract performance.
Pest/disease concerns
primary risk is botrytis due to extreme bud density. Good ventilation, humidity control below 45% in late flower, and strategic defoliation are essential preventive measures. The strain has average resistance to powdery mildew and standard pest pressures. Dry at 60°F/60% RH for 12-14 days; cure minimum 3 weeks in sealed jars for full terpene development.
History & Origin
Slurricane was created by In House Genetics in Washington state by crossing Do-Si-Dos with Purple Punch. The strain quickly gained recognition, winning 1st Place Best Indica at the 2019 High Times Cannabis Cup Oregon and 1st Place Indica at the 2020 High Times Cannabis Cup Nevada. The #7 phenotype emerged as the most famous and widely circulated cut, known for exceptional resin production, deep purple coloration, and a heavy grape-cream terpene profile. S1 seeds (selfed #7) were later released by In House Genetics. The strain has become a cornerstone breeding parent with 138+ documented descendants, including Sugar Cane, Terple, and numerous other In House Genetics crosses that shaped an entire generation of exotic genetics.
