If you’ve been searching for one of the gassiest, hardest-hitting strains of cannabis, the Motorbreath strain should be one you know about. Sometimes written Motor Breath, or called Motorbreath #2, this award-winning indica-dominant hybrid has built a serious reputation among experienced stoners. Born from a cross of Chemdog D and SFV OG Kush, it brings that unmistakable diesel funk in both smell and flavor. But this strain doesn't just smell and taste strong as it packs up to 33% THC, a 70/30 indica-to-sativa ratio, and can flower in about 8 to 10 weeks.
Over the years, Motorbreath marijuana has become a fan favorite across dispensaries in the U.S., even taking home first prize at the 2015 Cannabis Cup for best recreational hybrid. Its insane potency, knockout body effects, and bold flavor make it a go-to for experienced stoners who want serious relaxation. In this page, we’ll dig into everything you need to know about Motorbreath: from its history and lineage to its cannabinoid content, effects, terpene profile, and tips for growing your own.
So, what strain is Motorbreath? It is a true heavy-hitter with serious roots in the cannabis elite. The Motorbreath strain is a true heavy-hitter that was created by Pisces Genetics by crossing two legends: Chemdog D and SFV OG Kush, both of which bring high potency and strong flavors. Combine Chem D’s diesel-and-funk punch with SFV OG’s earthy-citrus smoothness, and you get a cannabis strain that’s as loud as it is sedating.
The most famous version of this cultivar is Motorbreath #15, a phenotype that exploded in the U.S. scene winning first place for the Best Recreational Hybrid at the 2015 Cannabis Cup. This specific phenotype is so demanded and rare that it's often only available as a clone. This strain quickly became a staple in both medical and recreational circles across North America. It’s even at the origin of other new strains like Motorbreath OG and the Motorbreath Haze strain.
If you're wondering if Motorbreath is indica or sativa, know that it is a 70% indica / 30% sativa hybrid. That means it leans heavily into the body-melting, couch-locking effects characteristic of indica strains, while still offering some uplifting mental buzz typical of sativa genetics. So you'll feel physically calm, chilled, and possibly couchlocked, but your mind will stay stimulated enough to enjoy a good movie, for example.
Depending on where you buy Motorbreath seeds and which phenotype you get, you might notice subtle differences in effects or flavor. This is pretty normal for strains that push the limits of cannabis breeding with extreme THC levels and high flavors. The term "clone-only" gets thrown around too, especially when people are talking about the top-tier Motorbreath #15 phenotype. So if you're looking for Motor Breath seeds or weed, keep in mind that the growers’ and breeders' reputation matters more than most other strains.
The Chemdawg strain (sometimes spelled Chemdog) is a 55% indica / 45% sativa hybrid that has been used to create dozens of iconic strains, including Sour Diesel and OG Kush. Known for its pungent diesel aroma, Chemdog delivers a heady cerebral buzz paired with a mellow body stone. Its THC levels typically reach around 19–20%, but it hits noticeably fast with a strong following. The strain’s origins are wrapped in legend, so read our Chemdawg strain info page to learn everything about it!
The other half of Motorbreath’s genetics is the SFV OG Kush strain, a 90% indica strain bred in California’s San Fernando Valley. The THC content is between 20–25%, and its aroma is unmistakable with notes of earthy pine and citrus. Effects start with a euphoric uplift before sinking into heavy relaxation, making it a go-to for stress and pain relief. This strain is the main actor in the potency of the Motor Breath strain effects, but it was even refined to reach THC levels above 30%.
The Motorbreath strain THC level can range anywhere from 25% all the way up to 33% in some cases. That kind of potency means it’s definitely not ideal for beginner stoners. Of course, as with any strain, the final potency depends on growing conditions, phenotype, and genetic quality. But regardless, this strain hits heavy and fast!
Regarding the CBD levels, they are generally well below 1%, which means the Motor Breath weed strain is all about the THC high and is not the best if you want a gentle therapeutic balance. That said, it does contain a little CBG (around 1%), which adds a touch of potential benefit for pain and inflammation. If you're looking for something more mellow or medicinal, Sirius has your back with high-quality CBD medicinal seeds and many CBD products in our CBDShop including a large selection of CBD Oils, CBD Capsules, and CBD Skin Care.
Part of the magic of any cannabis strain is how it smells, tastes, and looks, and the Motorbreath weed strain is for those who love a pure diesel-forward experience. From the second you crack open a ziplock bag, you’re hit with that unmistakable fuel and car oil aroma that will transport you back into your garage. Want to really experience everything this strain has to offer? Ditch the lighter and grab a proper vaporizer. By using one from our Vaporizershop, you’ll taste every terpene and maximize both flavor and effect without burning all the volatile compounds.
One puff of the Motorbreath cannabis and you’ll know exactly why it’s so hyped. It starts with that bold diesel and chemical taste, then eases into more nuanced flavors like earth, citrus, and even a touch of garlic and pine. It’s a seriously heavy taste that is far from being subtle. This might not be your ideal wake-and-bake strain and is definitely best enjoyed after dinner or just before bed, when you want to melt into the couch and savor the high.
Here’s a breakdown of the terpenes responsible for that powerful aroma and next-level effects:
Visually, Motorbreath is just as impressive as its flavor. Expect chunky, cone-shaped buds that are extremely dense. The colors of the buds are minty green with occasional hints of purple, and they are absolutely dripping in trichomes, which makes them look like they’ve been rolled in sugar. If you like sticky, resin-heavy flowers, this one’s a gem.
The Motorbreath strain effects hit in two phases: first comes a blast of euphoria, followed by a strong wave of pure chill. The high starts off in the head, which makes your mind clear and happy, and then it starts coming down your spine until you feel your body sink into a comfortable position. If you’ve had a stressful day or need serious help falling asleep, Motor Breath Weed is ready to help.
Medicinally, Motor Breath strain gets a lot of love from people dealing with chronic pain, insomnia, anxiety, and appetite issues. That high THC content and rich terpene mix (especially myrcene and caryophyllene) make it ideal for relaxing and easing physical fatigue.
Disclaimer: Motorbreath weed may offer symptom relief, but it can also trigger or worsen anxiety, depression, or other mental health conditions in some users. It's important to consult a healthcare professional before using cannabis as a form of treatment.
Even champs can get knocked out by this one. Here are a few things to watch out for:
Pro tip: know the THC and CBD levels of what you're consuming, or test your weed in a lab or at home if you do not have access to a reliable weed dispensary.
Thinking of growing your own Motorbreath strain? First, you’ll need to give this plant plenty of light, airflow, and nutrient-rich soil. It’s not overly hard to grow, but its dense buds require good humidity control to prevent mold. One way to improve airflow and boost yields is to apply cropping and lollipopping techniques, which are highly recommended for this strain. And to learn the most and improve as you grow, keep a week-by-week journal or check out an online grow report.
Growing the Motorbreath strain can be a rewarding experience for growers of all levels.
For the best results indoors, give Motorbreath strong lighting and solid airflow. Keep humidity around 50% once flowering starts to prevent mold in the fat and dense buds. You can find everything you need for a successful indoor grow in Sirius online Growshop, including high-quality grow tents, powerful grow lights, and reliable climate control equipment to maintain the perfect environment. Don’t forget to check out our Growshop offers for deals on pro-level gear that’ll take your setup to the next level.
If you are lucky enough to have a warm, sunny spot, the Motorbreath cannabis strain will thrive outdoors in temperate and Mediterranean climates. Just give it plenty of space, and make sure it’s well-fed with organic nutrients. Because of its thick bud structure, mold can appear late in the season, so keep airflow high and consider placing it in a well-aerated area. Our organic cannabis fertilizers are perfect for boosting terpene production and yields while keeping your plants healthy!
There is an autoflowering version of the Motorbreath seeds that stays true to the original with bold diesel flavors, tight buds, and up to 24% THC. Thanks to its added ruderalis genetics, it’s fast, sturdy, and ready to harvest in just 11–12 weeks from seed. Ideal for smaller grows or stealth setups, Motorbreath Auto reaches around 140 cm indoors and up to 170 cm outdoors, yielding up to 400 g/m² or 150 g per plant outside. Looking for other autoflower strains with big impact? Check out our extensive collection of autoflowering cannabis seeds.
While the original Motorbreath is a clone-only cut (especially phenotype #15), some breeders have created feminized seed versions. These are easier to find and more convenient for growers who want consistent results. Even though Sirius currently does not sell these seeds yet, you can check out our feminized cannabis seeds collection for similar premium genetics.
The Motorbreath strain is above most modern strains when it comes to knockout potency and strong diesel flavor, but how does it compare to other popular genetics? Let’s start with two premium-related strains you can find right now in Sirius' Seedshop.
If you like the Motorbreath strain but want to explore other flavors or effects, you might want to check out Motorbreath Haze and Frosted Motorbreath. The Motorbreath haze strain takes the original’s gassy taste and adds more Sativa effects, resulting in a more cerebral, great for daytime use with spicy, peppery notes. Meanwhile, Frosted Motorbreath brings up the THC even higher (sometimes reaching 35%) and introduces sweeter undertones to the already fuel-forward flavor profile. Both are solid alternatives depending on your vibe, and both maintain the bold Motorbreath strain effects that fans know and love.
Unfortunately, Motorbreath seeds aren’t currently available at Sirius. But if you’re serious about growing this legendary weed, we recommend sourcing from reputable breeders like Royal Queen Seeds or Growers Choice once they become available. Because this strain has such a big reputation, you need to make sure you’re getting the real genetics. We’re always in touch with top seedbanks to expand our collection, so don’t forget to check our seedshop offers regularly for discounted seeds.
In general, Motorbreath feminized seeds range between €35 and €60 for a pack of 3 to 5, depending on the breeder and the exact phenotype. While Sirius doesn’t currently stock this strain, we’re proud to offer great prices across our full product range, including premium seeds in our Seedshop, top-tier gear in our growshop, and everything from bongs and grinders to rolling papers and tips in our Headshop. No matter if you are growing, smoking, or both, you can get it all in one spot, saving you time and shipping costs.
