Motorbreath #15
The legendary powerhouse hybrid crossing Chem D with SFV OG—widely considered one of the gassiest strains ever created.
What is Motorbreath #15?
Motorbreath #15 is the crown jewel of Pisces Genetics. Bred by Jimmy Nitz, this specific #15 phenotype was selected for its offensive, industrial aroma and skull-crushing potency. It is a direct cross of Chem D x SFV OG, blending two of the most influential "gas" lineages in cannabis history into a single, devastating cultivar.
While many strains claim to be "gas," Motorbreath #15 defines the term. It delivers a sharp, acrid chemical stench that transitions into a deep, earthy funk. Unlike modern dessert-leaning hybrids, this is a true breeder cut for those who crave the old-school fuel profile. Starting with a verified clone ensures the authentic structure and terpene profile that made this strain a multi-cup winner and a staple in top-tier commercial gardens across the globe.
Terpene Profile
The Motorbreath #15 terpene profile is dominated by heavy concentrations of gas, fuel, and chemical notes. There is no sweetness here—only a raw, industrial pungency that can be smelled through multiple bags. It is a masterclass in Chem-lineage aromatics.
Growing Motorbreath #15
Motorbreath #15 is a grower's delight, but it requires a patient hand. It displays classic OG growth patterns—lanky branching that requires support—but with the added bud density of the Chem D parent. Expect a 2.5x stretch and a flowering time of 65-70 days for maximum potency.
Key Growing Tips
-
📏TrainingResponds excellently to topping and scrogging to manage the significant stretch.
-
🍽️NutritionHeavy feeder; requires high Calcium and Magnesium, especially in weeks 3-5 of flower.
-
🌬️AirflowBuds are incredibly dense; ensure high airflow in late flower to prevent moisture issues.

👃Odor ControlOne of the smelliest strains in existence—double-check your carbon filters.
Push this strain to 70 days. While the buds may look finished at week 8, the final 10 days are where the terpene complexity and the sedative THC levels truly peak.
Flower Quality & Bag Appeal
Motorbreath #15 produces connoisseur-grade flower that stands out for its unique "greasy" appearance. The buds are typically spade-shaped, dense, and possess a silver-green hue underneath a thick, sticky layer of resin. Bright orange hairs provide a sharp contrast to the lime-green foliage.
Unlike many modern "frosty" strains that have dry, sandy trichomes, Motorbreath is notoriously oily. When broken open, the buds release a scent so strong it can be physically stinging to the nose. This is premium flower designed for the heavy-hitter market.
Market Performance & Stats
Motorbreath #15 is a commercial powerhouse not because it "washes" well (it is generally not recommended for solventless extraction due to its oily resin), but because of its unrivaled flower quality and high THCA testing. It consistently commands top-shelf pricing in dispensaries.
Effects & Experience
The Motorbreath #15 effects are notoriously potent. This is not a "daytime" strain. It is a heavy-handed hybrid that lean's heavily into its Indica heritage, providing a potent body high that often results in deep sedation. It is frequently sought after by medical patients for chronic pain and insomnia.
