Quick read: 20% THC, 60-100cm mature height, 8-9 weeks bloom. Genetics: Proprietary cross (NorCal Farms). Difficulty: easy.

Smell-first: crack a jar of this and you're hit with damp earth and old-school skunk — the kind of nose that's been mostly bred out of modern genetics in favour of trendier terpene profiles. Old School OG Auto pulls that scent directly from NorCal Farms' proprietary indica lineage, and it carries through to the smoke with no surprises. At 20% THC it's not chasing records, but the effect is heavy and deliberate — body-forward, leaning hard toward evening use and sleep.

For growers, the numbers are straightforward: 8–9 weeks to finish, roughly 300 g/m² indoors, and an easy difficulty rating that holds up in both tent and outdoor runs. Canadian growers in shorter-season regions can start these mid-summer and still pull a harvest before temperatures drop below 10°C. Best suited to anyone tired of finicky photoperiods and just wanting a low-maintenance plant that smells like cannabis used to.

Genetics & Lineage

Old School OG Auto traces its genetics to Proprietary cross (NorCal Farms). This indica-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by NorCal Farms, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Old School OG Auto delivers THC levels of 20%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Old School OG Auto

Old School OG Auto is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 300g/m2. Plants typically reach 60-100cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Old School OG Auto features a earthy, skunky terpene profile that develops complexity throughout the flowering cycle. The complex aromatic bouquet develops fully after proper curing. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Old School OG Auto is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
