Also known as: Platinum (IHG), The Platinum

Breeder: In House Genetics

Platinum is the foundational backbone of In House Genetics' entire breeding program — a cross of UW Hashplant and Permafrost S1 that transformed IHG from a hobby operation into one of the most respected names in cannabis genetics. Named for its signature platinum-white trichome coverage, it delivers exceptional resin production, complex gas-pine-earth terpenes, and potent indica-leaning effects that have made it the parent of over 58 documented IHG hybrids including Sugar Cane, Platinum Kush Breath, 33rd Degree, and Dolato. In interviews, the breeders acknowledged that creating Platinum "really took their breeding game to another level," as the plant's exceptional trichome production, terpene intensity, and potency elevate any strain it is crossed with. The original cut emerged from a meticulous pheno hunt and has been maintained as both a clone-only selection and an S1 seed line. Its influence on the modern exotic cannabis market — particularly the resin-forward, bag-appeal-driven cultivars dominating dispensary shelves since 2020 — cannot be overstated.

Lineage & Genetics

Cross: UW Hashplant x Permafrost S1

UW Hashplant (mother) is a clone-only, nearly pure indica from the Pacific Northwest with a legendary origin story involving a clone reportedly taken from a University of Washington medical research lab in the early 1990s. It contributes stout indica structure, short internodal spacing, heavy sedative effects, deep purple color potential, dense bud formation, and powerful pain-relieving qualities. Permafrost (father) is a sativa-dominant hybrid (approximately 70% sativa / 30% indica) bred from Trainwreck x White Widow by Rogue Buds. Named for its frosty trichome coat, it contributes the crystalline trichome finish, pine-forward terpenes, the cerebral/euphoric component of the high, and hybrid vigor.

Lineage Dispute

SeedFinder.eu's breeder description field confusingly lists 'Lineage: Platinum Kush' with 'Indica / Sativa: 100/0,' which appears to be an error or shorthand in IHG's own catalog description — the verified genealogy tree on the same site unambiguously shows UW Hashplant x Permafrost. Additionally, Permafrost's own lineage has some dispute: while most commonly cited as Trainwreck x White Widow (bred by Rogue Buds), some sources claim it descends from Kali Mist x Trinity Snow. The Trainwreck x White Widow lineage is the most widely accepted version. This strain should not be confused with the older, unrelated 'Platinum OG' or 'Platinum Kush' varieties from different breeders.

Terpene Profile

DOMINANT

Caryophyllene — Contributes peppery, spicy, herbal depth; engages CB2 receptors for anti-inflammatory effects; consistently cited first in terpene descriptions

DOMINANT

Myrcene — Contributes earthy, musky base notes; enhances sedative and body-relaxing effects from the UW Hashplant heritage

DOMINANT

Pinene — Listed as dominant terpene on GrowDiaries; contributes sharp pine aroma from the Permafrost parent; may support alertness and counteract some sedative effects

SECONDARY

Limonene — Contributes citrus brightness noted in the S2 seed bank listing; adds uplift to the terpene profile

SECONDARY

Humulene — Contributes woody, herbal contours complementing the caryophyllene backbone

SECONDARY

Linalool — Possible minor contributor based on floral notes some reviewers describe

Aroma: Assertive and old-school — dominated by sharp pine, pungent skunk, and peppery spice with a sweet, earthy undertone. When buds are broken apart, the skunky dankness intensifies. A gassy, fuel-like undertone becomes more prominent in the S2 version. The overall character is classic Pacific Northwest indica with modern resin-forward aromatics — assertive, not fruity or dessert-forward.

Flavor: Mirrors the aroma but slightly lighter in intensity. Woody pine on the inhale with spicy, floral, skunky notes on the exhale. A subtle sweetness and savory skunk finish, with a pungent dank character that blends together spicy flowers and a punch of savory skunk throughout.

Effects & Experience

Onset: Relatively quick onset beginning with a tingle felt in the spine and limbs that slowly spreads throughout mind and body, creating a numbing sensation.

A contented, body-forward glow balanced by a buoyant mood and gentle euphoria. The numbing sensation leaves users feeling locked down and completely happy. Deep relaxation with a calm, happy headspace delivers both cerebral and physical effects. Suitable for experienced users due to high potency.

Duration: Long-lasting; the heavy indica body effects suggest sustained duration typical of resin-rich indicas.

Platinum is the strain that built In House Genetics' reputation, and growing it reveals exactly why. Bred from UW Hashplant crossed to Permafrost S1, this indica-dominant hybrid marries Afghan-lineage density with Pacific Northwest frost genetics to produce one of the most resin-forward plants in modern cultivation.

Growth Structure and Training

Presents a stout, bushy frame with short internodes of three to five centimeters under adequate light intensity, along with broad, dark-green leaflets characteristic of its Afghani heritage. The plant develops strong lateral branching and responds eagerly to topping, low-stress training, and SCROG netting. After the flip to flower, expect a structured but determined stretch of approximately 1.5x to 2x that continues into the second and third weeks — longer than most commercial indicas but never explosive. Sea-of-green layouts can succeed, though SCROG configurations tend to maximize canopy efficiency due to the slightly wider node spacing compared to pure Afghani lines.

Flowering Time and Harvest

Most phenotypes finish right around 60 days, with the breeder listing 60 days and Neptune Seed Bank extending to 60 to 65 days for the S2 version. The buds develop into dense, conical colas with a high calyx-to-leaf ratio that trims easily, a trait inherited directly from the UW Hashplant mother. Outdoor harvest falls in mid-to-late October in Northern Hemisphere temperate climates.

Nutrient Management

A moderate feeder that benefits from increased phosphorus and potassium in mid-bloom but punishes overfeeding — particularly excessive nitrogen — with muted terpene expression and unnecessary leaf mass. In coco or hydroponic systems, maintain pH of 5.7 to 6.2 with EC of 1.4 to 1.8 in early flower, stepping to 1.8 to 2.2 during peak bloom in weeks four through seven, then tapering in the final 10 to 14 days. In organic soil, target pH of 6.3 to 6.8 and rely on top-dressed amendments rather than aggressive liquid feeds. Calcium and magnesium supplementation is advisable under LED lighting.

Growing Media

Performs reliably in both soil and hydroponic systems. Precision irrigation cycles and stable root zone oxygenation frequently produce better results than chasing high runoff numbers. Coco-perlite blends work well for growers targeting maximum resin development, while living soil builds can enhance terpene complexity through the microbial contributions to secondary metabolite production.

Environment and Climate

Target daytime temperatures of 75 to 80 degrees Fahrenheit during veg, dropping slightly to 73 to 78 degrees in flower, with nighttime temperatures three to five degrees cooler to promote terpene retention and encourage subtle color expression. Humidity should step down through flowering: 55 percent in weeks one through three, 50 percent in weeks four through six, and 40 to 45 percent in weeks seven through nine. Maintain VPD of 1.2 to 1.4 kPa in mid-flower trending toward 1.4 to 1.6 kPa in late flower to reduce Botrytis risk on the extremely dense colas.

Lighting

Under modern LEDs, target 800 to 1000 micromoles per square meter per second PPFD in mid-to-late flower for maximum resin development without bleaching. The heavy trichome production that gives Platinum its name responds directly to light intensity, with the signature frost becoming most pronounced under high-output fixtures during peak bloom.

Pest and Disease Resistance

The primary concern is bud rot from Botrytis cinerea. Rock-hard flower density inherited from UW Hashplant creates microclimates inside large colas that trap humidity. Aggressive horizontal airflow, canopy defoliation at strategic intervals, and strict late-flower humidity control are non-negotiable. The plant carries some mold resistance from its Pacific Northwest lineage — UW genetics were maintained outdoors in Washington's damp climate — but this supplements rather than replaces environmental management. Powdery mildew can appear if airflow stagnates. Preventative Bacillus or potassium bicarbonate sprays through late veg provide a solid defense.

Yield

Indoor yields range from 400 to 500 grams per square meter under optimized conditions, with individual plants producing 200 to 250 grams when given adequate space and training. This is not a biomass-first cultivar — In House Genetics selected for resin quality over raw weight — but disciplined canopy management and proper VPD control push production into commercially viable territory. Outdoor plants can produce 600 to 800 grams per plant in favorable Mediterranean climates with extended vegetative time.

Bud Structure and Trichomes

By week four of flower, trichome coverage becomes the defining visual characteristic: a thick, silvery-white blanket of large-headed glandular trichomes that gives the cultivar its name. Under magnification, the stalked heads appear enlarged in the 100 to 120 micron range, a morphology specifically selected by In House Genetics for extraction performance. The buds form hard, conical colas with bright emerald-green nugs, deep purple leaves, thick orange hairs, and a super frosty blanket of sparkling platinum-white crystal trichomes.

Color Development

Purple hues inherited from UW Hashplant can emerge under cooler late-flower nighttime temperatures, typically below 65 degrees Fahrenheit. Some phenotypes develop deep purple leaves contrasting against emerald-green calyxes, though Platinum is primarily famous for its platinum-white trichome frost rather than purple coloration. Not all phenotypes express purple regardless of temperature manipulation.

Drying and Curing

Slow drying at 60 degrees Fahrenheit and 55 to 60 percent relative humidity for 10 to 14 days is essential. The extreme bud density means interior moisture dissipates slowly, and rushing the dry will leave pockets of undried material that compromise the cure. Slow curing in sealed vessels for three to six weeks at 58 to 62 percent humidity develops the full terpene complexity — the pine-skunk top notes deepen, and sweet, earthy undertones emerge alongside spicy herbal accents from the caryophyllene-myrcene-pinene triad.

Wash and Extraction

Platinum is an elite wash candidate and a primary reason In House Genetics uses it as a breeding parent. The enlarged trichome heads separate cleanly in ice water, and keeper phenotypes deliver fresh-frozen wash yields in the 4 to 6 percent range with rosin press returns of 16 to 22 percent from hash. The resin texture tends toward sandy rather than greasy, producing shelf-stable concentrates with excellent terpene preservation. Fresh-frozen processing captures the full volatile profile best.

History & Origin

Platinum was created by In House Genetics (IHG), a boutique micro-breeding operation based in Washington State founded by Branden Bond and a small team with over 20 years of combined growing experience. The company was formally incorporated in Lynnwood, Washington on July 3, 2019, though the breeding operation predates the LLC by several years. The creation of Platinum — a cross of UW Hashplant (a clone reportedly obtained from the University of Washington) and Permafrost (Trainwreck x White Widow) — transformed IHG from a hobby breeding operation into one of the most respected names in cannabis genetics. In interviews, IHG admitted that Platinum really took their breeding game to another level, as the plant's exceptional trichome production, terpenes, and potency elevate any strain they cross it with. From Platinum came Slurricane, then Sugar Cane, Dolato, Black Cherry Punch — a cascade of iconic strains that changed what growers expected from boutique genetics. Today IHG has released over 263 strains, with 47 of them using Platinum as a direct parent. IHG further selfed Platinum to produce Platinum S2 (sold as a premium collector's pack at $500 for 10 seeds) to stabilize the line.
