Born from Top Dawg Seeds, Sour 91 stitches two East Coast icons into one expressive hybrid: Chem 91 and Sour Dawg (Sour Diesel x Tres Dawg). In veg, plants show vigorous branching and a predictable, medium indoor stature that stretches moderately when flipped; outdoors they reach tall, staking-worthy heights. By day 63–70 the canopy frosts over, delivering bag-appeal buds that reek of classic petrol layered with citrus peel and fresh pine. Expect a terpene ensemble led by myrcene, beta-caryophyllene, and alpha-pinene, translating into that unmistakable diesel snap on the grind. Typical batches test around 18–22% THC with trace CBD, driving a two-stage experience: a bright, happy lift that sharpens focus and encourages conversation, followed by a calm, even-bodied settle. Chem 91 lends the greasy trichomes and taut, spear-tip structure; Sour Dawg extends the frame and adds tart sourness. Yields land in the medium range—roughly 450 g/m2 inside and up to 600 g per plant outside—while simple training keeps internodes packed. Growers rate difficulty as moderate: keep airflow moving, dial feed sensibly, and Sour 91 rewards with pungent, old-school fuel that lingers.
