Thin Mint x Sour Pinot Auto by Barney's Farm

Thin Mint x Sour Pinot Auto is a special-edition autoflower that Barney’s Farm assembled from two of its own fast lines: Thin Mint Auto and Sour Pinot Auto. The headline number is hard to ignore: 26% THC in a plant that finishes in 70–75 days from seed.

The cross leans 60% Sativa, 40% Indica, and it carries a remarkably layered terpene profile. Grape, diesel and mint rarely share the same bud, yet here they sit side by side, wrapped in a thick coat of trichomes that gives the flowers a frosted, almost sugared look.

Plants grow lush and vivid green, reaching 90–120 cm (35–47 in) indoors and 110–140 cm (43–55 in) outdoors. When night temperatures drop during bloom, purple and blue hints can creep into the bracts. Indoor harvests land around 450–500 g/m² (1.47–1.64 oz/ft²), with 180–250 g (6.3–8.8 oz) per plant outdoors.

It is a strong pick for growers who want a high-potency, flavor-heavy auto that still fits a standard tent.

Lineage: Two Autos, One Special Edition

Thin Mint Auto brings the cookie side of the family: minty, earthy, dense and resin-soaked. Sour Pinot Auto contributes the fruit, with grape notes and a sour, pungent bite.

Because both parents were already autoflowering, the offspring keeps a reliable flowering trigger and a predictable timeline. Barney’s Farm describes it as one of the standout varieties in its autoflower range, selected for potency and that unusually wide terpene spread.

Aroma, Flavor and Effect

The aroma reads like a walk through a herb garden after rain: earthy soil, sweet fruit, cool mint and fresh herbs, with a pungent backbone that lingers in the room.

On the palate, diesel arrives first and sharp, then grape and sweet berry flood in before an earthy finish settles everything down. It tastes like a glass of dark red grape juice poured next to a running generator, with a sprig of mint on the rim. Strange on paper, oddly addictive in practice.

Barney’s Farm lists the effects as creative, euphoric, relaxing and sociable. With 26% THC, it hits with real force. The sativa share sparks conversation and ideas, while the indica side keeps the body loose and calm. It suits social evenings and creative sessions, and newer consumers should start with a light hand.

Growing Thin Mint x Sour Pinot Auto Indoors and Outdoors

Run 18/6 or 20/4 from germination to harvest; the plant will switch to flowering without any change in photoperiod. Sow into the final container if possible so the taproot never gets disturbed.

Indoors, the 90–120 cm (35–47 in) frame benefits from gentle LST in weeks 2 to 4 to spread the branches and expose more bud sites. Keep humidity in check during late bloom because the buds pack tightly. Dropping night temperatures a few degrees in the last two weeks can coax out those purple and blue tones without slowing the plant.

Outdoors, give it full sun and airy soil. Plants reach 110–140 cm (43–55 in) and produce 180–250 g/plant (6.3–8.8 oz/plant). The 70–75 days cycle makes a late-spring sowing ready well before autumn weather turns.
