Banana OG is a piece of Humboldt history in seed form. The original was a clone that circulated in the Emerald Triangle around 2010, guarded by growers in the coastal surf town of Trinidad. Humboldt Seed Company turned that cut into a stable feminized line with THC averaging over 25%, banana taffy sweetness and a fuel-soaked OG exhale.
The breeder recreated it the same way it preserved other Emerald Triangle clone classics such as Trainwreck and Headband: by selfing and backcrossing the original clone until the seed line reliably reproduced its traits. The current release combines the Classic Banana OG clone with Banana OG S1 #21 and Banana OG Bx3.
Growers get a productive, upright plant with frosty golf-ball buds, hardly any leaf to trim, and giant colas brushed with purple mottling. It also showed resistance to powdery mildew, the classic weak point of OG genetics, along with other fungal pathogens.
Lineage and Breeding: Rebuilding a Trinidad Clone
Clone-only strains disappear when the last mother plant dies. Humboldt Seed Company’s approach is to self the clone, then backcross the offspring until the seed line consistently expresses the original. For Banana OG that work produced a stack of Classic Banana OG Clone x Banana OG S1 #21 x Banana OG Bx3, a line that keeps the cult classic’s character while giving growers the reliability of feminized seed.
During trials the breeder found Banana OG to be insanely productive and a strong washer, with excellent returns in both the photoperiod version and the autoflower conversion. That makes it a natural fit for rosin makers and for brands that want a cult classic nobody else is running.
Aroma, Flavor and Effect
The nose is banana taffy layered with fuel, a candy-gas profile that fills a room the moment a jar opens. On the inhale the banana leads, sweet and almost chewy. On the exhale the OG side takes over with sharp fuel terpenes that coat the palate, like unwrapping banana candy in a garage where the engine is still warm.
The effect is classic OG with a Sativa uplift. A heavy, familiar OG body feel grounds the session while the head stays bright and engaged, so it never feels one-dimensional. With THC averaging over 25%, it is potent enough to command respect and suits consumers who know their limits.
Growing Banana OG Indoors and Outdoors
Indoors, Banana OG grows upright with little leaf, which keeps light penetration high and trimming quick. A simple topping or mainlining approach creates several even colas, and a light SCROG helps support the weight of the giant flowers. Plan on 55-65 days of flowering depending on phenotype and how ripe you like the trichomes.
Outdoors, Banana OG finishes between October 1 and 10. Its resistance to powdery mildew and other fungal pathogens gives it an edge over many OG cuts in coastal fog or humid late seasons. Full sun and generous root space let it reach its full production potential, and cool nights bring out the purple mottling on the frosty green colas.
