End of September outdoor harvest time cannabis strains are ones where the breeder's put a late-September harvest window on the packet. They're usually indica-heavy or speedy hybrids that wrap up flowering before autumn properly kicks in.
Their genetics often come from places where the legal growing season's short, so plants learned to finish fast, and loads have been tweaked over the years to get ready early in cooler spots.
Read MoreWhere these strains evolved
So where did these quick finishers come from? A lot of them started life in places where summer doesn't hang around. Think mountainous bits of Central Asia, where indica plants had to get a move on before the cold rolled in.
Over time, breeders in northern Europe and North America spotted those fast traits and crossed speedy indicas with hybrids that still packed plenty of resin.
The result is a bunch of strains that can finish up in temperate zones before October weather turns nasty, and that's why collectors interested in shorter-season genetics keep coming back to them.
Standout examples of end of September harvest strains
Jamaican Dream wraps up around the third week of September up north, which is mad early for a sativa-leaning strain. It's got this soft, sweet taste with a nutty edge, almost like almond, and that quick turnaround makes it a go-to for early-autumn genetics.
Exodus Cheese from Green House Seeds is done by late September, so it dodges the worst of the weather and still delivers that proper Cheese vibe.
Northern Lights, whether it's the Sensi Seeds or Canuck Seeds version, hits mid to late September, and those indica genes have kept them famous for decades. Kritikal Bilbo by Genehtik Seeds is said to be ready around mid to late September too.
Frisian Dew is a photoperiod fem from Dutch Passion that they say is ready late September or early October, mixing indica speed with hybrid punch.
Sugar Black Rose from Delicious Seeds gets there early enough for September even up near the forty-ninth parallel, where autumn doesn't mess about.
Sweet God by BCBD is meant to finish by mid-September, and it's a cross between God Bud and Sweet Tooth, which makes it interesting for collectors in places like southern Ontario where the weather turns fast.
C99 is a sativa-leaning strain that still counts as a quick finisher, it can wrap up by the end of September even in northern spots, which is unusual for a sativa.
Indica-heavy hybrids with eight-week flowering times also fit the bill for September harvests in cooler places, and breeders often point to strains like MK Ultra, Dinachem and Holy Grail as examples of that quick-finish blueprint.
Pure indicas are reportedly usually done outdoors by the end of September in most temperate zones, finishing their cycle in late September as a rule.
Indicas mostly mature faster and are said to often be ready by late September, wrapping flowering in seven to nine weeks.
Most photoperiod strains finish between late September and mid-October outdoors under natural light, and the end of September is said to be pretty much the earliest typical window for northern hemisphere outdoor harvests.
Autos planted in June or July can apparently be done by late September or early October too, strains like Auto Mazar take about a hundred days from seed to finish and bring a proper hashy flavour.
If you're into early-finishing genetics, these strains show off decades of breeding for quick maturation, solid resin and a bit of toughness when the first autumn chill shows up.
End of September Frequently Asked Questions
It means the breeder reckons the strain will be ready around late September when legally grown outdoors in temperate northern spots. It's a rough guide, not a fixed date.
Strains that finish by late September are usually indica-heavy or quick hybrids bred for shorter flowering. Their genetics often come from places with short growing seasons, where finishing fast before autumn weather was essential.
Most are indica-heavy or indica-leaning hybrids, because indica genetics usually mature faster and are often done by late September. Some speedy sativa hybrids like C99 fit this window too, but pure sativas usually need longer.
Green House Seeds, Sensi Seeds, Canuck Seeds, Genehtik Seeds, Delicious Seeds and BCBD all offer strains that finish by late September. Dutch Passion and other European breeders have also put out early-finishing lines for northern climates.
Yeah. Strains like Auto Mazar take around a hundred days from seed to finish, so they fit this window nicely.
Many trace back to Central Asian indica landraces and northern European breeding scenes, where shorter seasons and cooler autumns favoured fast-maturing genetics. North American breeders have also selected for early-finishing traits in temperate zones.
Not really. Strains like Northern Lights and Exodus Cheese finish by late September and are known for strong cannabinoid profiles.
End of September strains usually have shorter flowering cycles and more indica-heavy genetics, whilst October harvest strains often include longer-flowering hybrids and some sativa-leaning lines. The difference is often just a few weeks in flowering time.
Yeah, they're often bred for northern climates where autumn arrives early. Strains like Sugar Black Rose and Sweet God are said to be recommended for regions near the forty-ninth parallel, where cold weather and rain can start in early October.
Many have earthy, hashy or sweet profiles that come with indica genetics. Jamaican Dream offers a soft, sweet flavour with a nutty hint like almond, whilst Exodus Cheese delivers the classic Cheese character. Auto Mazar is noted for its hashy taste.
