Motorbreath 15 strain guide
Motorbreath 15 is the Pisces Genetics cut of Motorbreath, a cross of Chemdawg and SFV OG Kush, known for a strong diesel smell and a relaxed feel. The 15 refers to the specific plant picked from the original seeds.
Where does Motorbreath 15 come from?
Motorbreath 15 comes from a cross of Chemdawg and SFV OG Kush made by Jimmy Nitz of Pisces Genetics. Several strain databases give those parents. One strain database adds that the number 15 plant was reportedly picked out by a forum grower known as Sticky Icky OG.
That makes it a selected cut, not a different cross. It's treated as the standard Motorbreath, though other cuts circulate under the name and menus also list a separate Motorbreath #7.
What does Motorbreath 15 smell and taste like?
The smell is loud: diesel and gasoline first, then pepper, earth, a little pine and lemon peel. One strain database jokes that it smells like it came with an exhaust manifold.
One strain database lists myrcene first, followed by limonene and caryophyllene. Two strain databases don't publish terpene numbers.
Motorbreath 15 effects: what people report
People most often call it relaxed, happy and euphoric. Several describe a quick, clear lift that gives way to a heavier body feel, with sleepiness more common in longer sessions or at higher amounts.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth, dry eyes and dizziness are the usual complaints.
How strong is Motorbreath 15?
Sources disagree. One strain database's description says 18% to 22% THC, while two strain databases give 21% to 29%. Individual lab reports run higher, and one Illinois review cites about 29% THCA, the raw form before heating. Our THCA vs THC guide explains the difference.
Start with a small amount and wait before having more. The numbers on your package matter more than the strain name, and the reading cannabis labels guide covers them. One strain database lists it as roughly 70% indica and another database as 80%, so it's an indica-leaning hybrid.
Buying Motorbreath 15 in Canada
Check the label for the 15. Plain Motorbreath can mean different cuts, and one reviewer said a heavily reworked version was no longer really Motorbreath, which is one person's opinion.
You might find it as flower, pre-rolls, vape cartridges or concentrates. Check the THC and CBD numbers and the packaging date.
Motorbreath 15 vs Motorbreath
Motorbreath is the broader name and Motorbreath 15 is one specific cut of it, the Pisces Genetics plant that one strain database treats as the standard. That database also says the two names are used almost interchangeably, so the cross is the same: Chemdawg and SFV OG Kush. What can differ is the grower and the cut, which is why plain Motorbreath can smell a bit different from batch to batch. If you want the cut most people mean, look for the 15 on the label.
