What is the Motorbreath strain?

Motorbreath is a California cross that put two of the gassiest families in cannabis into one plant. On one side sits Chemdawg, the old-school diesel line that sits behind a long list of modern fuel strains. On the other is SFV OG Kush, an OG selection from the San Fernando Valley prized for sharp lemon-pine notes and a sturdy, productive frame.

The pairing does exactly what the parents suggest. Chemdawg brings vigor, branching and that unmistakable exhaust-pipe funk. SFV OG adds structure, citrus peel and the heavy, settled finish OG fans look for. The plants grow medium to tall with strong lateral branches, and the buds come in chunky and deep green under a thick, greasy layer of resin.

The name is a fair warning. Open a jar and the first thing most people notice is fuel, loud enough to fill a garage. Growers choose it for that nose and for its potency. These are feminized seeds, so each one you sprout is bred to grow into a flowering female.

How it feels

Consumers commonly report a warm, chatty lift that settles into long, steady body relaxation, with a strong appetite and drowsiness near the end. Most describe a session lasting two to four hours.

First 10 minutesEngine turns over
A bright, warm mood boost that often gets people talking.
30 to 90 minutesIdling body calm
Deep, even relaxation spreads through the shoulders and legs.
2 to 4 hoursSnacks, then sleep
Hunger shows up reliably, and many people drift off afterward.

Commonly reportedRelaxedEuphoricHungrySleepy

With reported THC up to 28%, go slowly and save it for the evening. Dry mouth and dry eyes are the most common complaints, and some people report racing thoughts or anxiety at high doses. General reports, not medical guidance.

Aroma, flavor and terpenes

Diesel and gasoline lead, with sour lemon peel and black pepper behind them and damp earth on the exhale. In late bloom the smell travels, so run a carbon filter sized for your tent.

Flavor notesGasLemonPepperEarthy

CaryophyllenePepper, wood

LimoneneLemon, citrus peel

Cuts through the fuel with a sour lemon edge.

Hang branches whole at about 60°F and 60% RH for 10-14 days, then cure in jars. A slow dry protects the volatile fuel notes that a fast dry burns off.

How to grow Motorbreath

Rated moderate. The plant is vigorous and forgiving through veg; the work comes in the long flower, when dense colas need dry air and steady airflow.

Indoors

Veg climate: 75-82°F, 55-65% RH
Flower climate: 68-80°F, 40-45% RH
Stretch: Expect about 1.5x after the flip
Light: 800-1,000 PPFD in flower (LED)
Training: Top twice, then a SCROG net
Feeding: Medium-heavy; taper nitrogen by week 3

Outdoors

Plant out: After last frost, nights over 50°F
Size: 5-7 ft in full sun
Harvest: Mid October
Best fit: Dry autumns (USDA 7-10)
Watch for: Bud rot in a wet October
Odor: Very loud; site it away from neighbors

Read the full indoor grow guide

Motorbreath runs a little longer than most indica-leaning hybrids, so plan your space around a 9-10 week bloom. It grows 3 to 5 feet indoors and stretches noticeably after the flip, which makes a 4×4 ft tent the comfortable size. Expect a moderate grow: easy in veg, more demanding in the last month.

Environment

Vegetative: 75-82°F with 55-65% relative humidity.
Flower: 68-80°F and 40-45% RH. Keep it toward the low end from week six onward, when colas pack on weight and bud rot becomes the main risk.
Airflow: fans moving air both over and under the canopy, plus an exhaust fan pulling through a carbon filter.

Light and training

Run about 600-800 PPFD in late veg and 800-1,000 PPFD in flower under LED. The chem side branches hard, so topping twice and spreading the tops under a SCROG net turns that vigor into an even canopy. Clear the lower third of the plant around day 21 of flower; those shaded sites rarely fill out.

Feeding

It takes a medium to heavy feed in veg and early bloom. Taper nitrogen by the third week of flower and lean on phosphorus and potassium. Watch leaf tips: OG-family plants show nutrient burn quickly if EC climbs too high.

Harvest timing

Most plants are ready 9 to 10 weeks after the switch to 12/12. Check trichomes with a loupe. Cloudy heads with a small share of amber give the classic heavy finish, while pulling earlier keeps the opening lift brighter.

Seed to jar in about 23 weeks

A typical indoor run. Veg time is your call; the long bloom is set by the chem-OG genetics.

Growing Motorbreath outdoors in the US

Outdoors, Motorbreath wants long sun and a dry fall. Plants usually reach 5 to 7 feet and finish around mid October, which is late enough that the weather in the final two weeks decides the harvest. Set plants out after your last spring frost once nights hold above roughly 50°F.

Two things deserve planning. First, the colas are thick and resinous, so an early autumn storm can start mold from the inside of a bud. Space plants widely, strip interior leaves for airflow and keep a rain cover ready. Second, the fuel smell is strong outdoors too, so pick a spot that keeps you on good terms with the neighbors. Our outdoor planting guide lists timing by USDA zone.

Check your state’s rules before you plant. Adult home growing is legal in some states and not others, and plant counts differ. See marijuana laws by state.

Will it finish where you live?

ExcellentInland California and the Southwest

Dry, sunny Octobers carry the long bloom to a full, clean finish.

FairColorado Front Range and Utah valleys

A mid-October finish can run into the first hard frost at elevation.

GoodMidwest

Strong summer growth, as long as you watch for cold rain in the final weeks.

FairNortheast

Short falls and damp nights push the finish; a greenhouse helps.

FairSoutheast and Gulf Coast

Heat suits it, but muggy autumn air threatens dense colas.

Motorbreath FAQ

Is Motorbreath indica or sativa?

Motorbreath is an indica-dominant hybrid. Its effects lean toward body relaxation after a brief, upbeat start, and the plant grows with the sturdy, branching frame you would expect from a chem and OG cross.

How strong is Motorbreath?

Our supplier reports THC in the 24-28% range, which places it firmly in high-THC territory. Actual numbers depend on phenotype, environment and when you harvest, so read the range as a typical outcome rather than a promise.

How long does Motorbreath take to flower?

Plan on 9 to 10 weeks of flowering after you switch the lights to 12/12. Outdoors in the US, it usually finishes around mid October.

How much does Motorbreath yield?

A well-run indoor space can produce around 1.5 to 1.8 ounces per square foot. Outdoor plants in full sun can produce roughly 18 to 21 ounces each, depending on season length and care.

Is Motorbreath good for beginners?

It is rated moderate. Veg is easy, but the long bloom and dense colas ask for tight humidity control, so a grower with one or two harvests behind them will have the easiest time.

What does Motorbreath smell and taste like?

Gasoline and diesel dominate, followed by sour lemon, black pepper and an earthy finish. Caryophyllene, myrcene and limonene are the terpenes most often associated with that profile.

Where does Motorbreath grow best in the US?

Inland California and the Southwest give it the long, dry October it needs. Wetter or colder regions can still finish it with a greenhouse, a rain cover or an indoor grow.

How do I control the smell when growing Motorbreath?

Indoors, run an exhaust fan through a carbon filter matched to your tent volume and keep the space under slight negative pressure. Swap the filter carbon on schedule, because the odor peaks in the last three weeks of flower.
