Beginning of November outdoor harvest time cannabis strains are those where breeders mark an approximate outdoor harvest window around the start of November on their own materials.
These seeds mostly carry sativa-leaning or long-flowering hybrid genetics that need extended warmth and daylight to finish properly. In the northern hemisphere, outdoor cannabis harvest generally runs from mid-September through mid-November, and strains labelled for early November sit towards the end of that window.
Read MoreWhere these strains evolved
Where do late-finishing strains come from? Most trace their roots to equatorial and subtropical places where long summers and mild autumns let cannabis flower for ages.
Many draw on sativa landraces from near the equator, Southeast Asia, Central and South America, parts of Africa, where plants evolved to ripen slowly under steady light and warmth.
Breeders in California and the Mediterranean have also played a big part, selecting and stabilising lines that can handle cooler nights and shorter days in late October and early November.
These genetics tend to favour taller, less dense bud structures and longer flowering cycles, traits that suit the tail end of the outdoor season in temperate zones with extended legal growing windows.
Standout examples of beginning of November harvest strains
What makes these strains worth knowing about? Colombian Gold is a classic tropical sativa landrace known for its drawn-out flowering period, said to usually finish outdoors in November across temperate climates.
Its roots lie in the highlands of Colombia, where warm conditions and long seasons allowed the strain to develop its slow maturation. Chocolate Thai, a Southeast Asian landrace, flowers for up to fourteen weeks and is another well-known example that pushes into November in northern hemisphere legal grows.
Both strains carry the equatorial genetics that define this harvest window, and both have earned reputations among collectors for their historical significance and distinctive terpene profiles.
Dr. Grinspoon, a sativa strain bred to honour the Harvard psychiatrist, shows the same prolonged flowering typical of equatorial lines and is often cited as a great strain for those interested in late-season genetics.
San Francisco Valley OG, a sativa-leaning hybrid, also needs extended flowering and usually finishes around early November outdoors, reflecting its West Coast breeding heritage.
Super Silver Haze, a multi-award-winning sativa-leaning hybrid, is another strain that breeders recommend harvesting in late November or even December in warmer regions like northern California.
Its lineage blends Haze, Skunk and Northern Lights genetics, and it's won multiple Cannabis Cup titles for its potency and complex terpene character.
These strains share a common thread: they need long, warm autumns to reach full maturity, and their genetics have been shaped by some of the most storied cannabis-growing regions in the world.
Meanwhile, certain indica-leaning hybrids bred for milder climates can also fall into this window when in Mediterranean or Californian conditions, where legal growers can extend the season well into November without facing the early frosts common further north.
Beginning of November Frequently Asked Questions
It means the breeder reckons that strain will reach maturity around the start of November when grown outdoors in suitable conditions. It's a catalogue reference, not cultivation advice.
These strains usually carry sativa-leaning or equatorial genetics that evolved under long, warm growing seasons, so they need extended flowering periods to reach full maturity.
Many trace back to equatorial and subtropical zones, Southeast Asia, Central and South America, parts of Africa, as well as breeding scenes in California and the Mediterranean where mild autumns permit late harvests.
No. While many are sativa-leaning or sativa landraces, some hybrids and indica-leaning lines bred for warmer climates can also finish around this time when conditions allow.
Colombian Gold is a tropical sativa landrace with a drawn-out flowering cycle, historically finishing in November outdoors. Its highland Colombian origins and slow maturation make it a classic example of late-season genetics.
Chocolate Thai, a Southeast Asian landrace, flowers for up to fourteen weeks, placing its outdoor harvest in November across temperate northern hemisphere climates.
Super Silver Haze is a sativa-leaning hybrid with Haze, Skunk and Northern Lights lineage. Breeders recommend late November or even December harvests in warmer regions like northern California because of its extended flowering period.
Not exclusively. While many carry equatorial genetics, breeders in California and the Mediterranean have also developed and stabilised lines suited to early November harvests in milder climates.
Breeder datasheets provide estimated harvest windows based on the strain's genetic background and typical flowering duration, helping collectors understand where a strain fits within the autumn season.
Pure indicas usually mature earlier, but certain indica-leaning hybrids bred for Mediterranean or Californian climates can extend into early November when legally grown in regions with long, warm autumns.
