Banana OG Auto revives a cult Emerald Triangle clone in a fast, stable autoflower. The original cut circulated around 2010 among growers in Trinidad, the coastal surf village in Humboldt County, and Humboldt Seed Company has now captured it in seed form with banana taffy sweetness, fuel terpenes, and about 25% THC.
Expect giant frosty green colas with purple mottling, golf-ball buds that carry hardly any leaf, and an upright frame that keeps the canopy tidy. The breeder reports amazing yields and notes that the line also impressed as a washer, in both the photoperiod and autoflower forms.
It finishes about 80 days from seed, making it one of the faster ways to get an old-school OG into the jar.
Banana OG Auto Lineage and Breeding
Humboldt Seed Company keeps classic clone-only strains alive by selfing and backcrossing the cut until the seed line reliably shows the traits of the original. The breeder has done the same with other Emerald Triangle classics such as Trainwreck and Headband.
For the auto, Banana OG S1 #21 was crossed with Mint Jelly Auto, then worked back toward Banana OG to reach the Banana OG Auto Bx3 line. The auto parentals are listed as Banana OG S1 #21 x Mint Jelly Auto x Banana OG Auto Bx3. During testing, the strain also showed resistance to powdery mildew, the classic OG weak spot, as well as other fungal pathogens.
Aroma, Flavor, and Effect
The smell lands squarely on banana taffy: sweet, chewy, a little artificial in a fun candy-shop way, with fuel rising behind it. The flavor works in two steps, banana on the inhale and a sharp fuel exhale that reminds you this is still an OG at heart.
The effect is described as a classic OG experience with a sativa uplift. It opens with a lifted, talkative headspace and enough energy to stay on your feet, then settles into the familiar OG body weight later on. At an average of 25% THC, it is potent enough for experienced consumers.
Growing Banana OG Auto Indoors and Outdoors
Banana OG Auto flowers by age, so no 12/12 switch is required. Indoors, run 18/6 or 20/4 for the whole cycle and plan for roughly 80 days from seed to harvest. Its upright growth and low leaf-to-bud ratio make it easy to manage in tents and quick to trim at the end.
Light LST in the first weeks helps spread the main cola and the side branches for more even colas. Outdoors, give it full sun and a large container or bed; the reported resistance to powdery mildew is a real plus in humid coastal regions. For rosin makers, harvest at peak resin maturity and consider fresh-frozen material to make the most of its washing potential.
