Motorbreath #15
Also known as: Motorbreath 15, Motor Breath #15, MB-15
Overview
Motorbreath #15 is an indica-dominant hybrid cannabis strain developed by Jimmy Nitz of Pisces Genetics through crossing Chemdog D and San Fernando Valley OG Kush (SFV OG). Originally bred by Pisces Genetics and later selected by a cannabis forum member known as 'sticky icky og,' this strain has gained legendary status particularly on the West Coast as a cornerstone of modern gas strains. The strain features a powerful genetic lineage combining the diesel-forward characteristics of Chemdog D with the earthy, pine-forward traits of SFV OG Kush, resulting in an exceptional terpene-rich cultivar.
Physically, Motorbreath #15 produces dense, round, spade-shaped buds with bright green coloration occasionally accented by purple and blue hues. The flowers are completely covered in sparkling trichomes with long, bright orange pistils, indicating high resin production. The strain is renowned for its intensely pungent aroma dominated by diesel fuel scents mixed with earthy musk, sharp citrus notes, and subtle hints of pine and chemical undertones. Users often describe the smell as reminiscent of motor oil with a sharp, almost paint thinner-like quality that commands attention in any room.
Motorbreath #15 typically exhibits a 70% indica to 30% sativa ratio, making it ideal for evening use and deep relaxation. The strain has achieved cult status among cannabis connoisseurs and has won multiple awards including 1st place for recreational hybrid at the 2015 THC Championship and 2nd place for recreational indica at the 2016 THC Championship. Its combination of potent effects, distinctive aroma, and exceptional terpene profile has made it a highly sought-after strain, with certain phenotypes available only through verified clone networks, increasing their desirability and exclusivity in legacy markets like California.

Growing Information
Motorbreath #15 is considered moderately difficult to grow, requiring precise environmental control and attention to detail. The strain has a flowering time of 8-10 weeks (60-70 days) and can be cultivated both indoors and outdoors. Indoor plants typically reach heights of 3-4 feet, while outdoor varieties can grow 5-8 feet tall. The strain prefers warm, sunny Mediterranean-style climates with stable temperatures and low humidity. Indoor yields average around 400 grams per square meter (1-2 ounces per square foot), while outdoor plants can produce up to 550 grams per plant. The bushy structure with strong lateral branching benefits from Screen of Green (ScrOG) training methods to improve airflow and light penetration. Due to dense bud structure, proper spacing and airflow are essential to reduce mold risk. The strain responds well to phosphorus-forward nutrients during flowering and benefits from light defoliation in late vegetative stage.
