The specs in one line: 18-25% THC, <1% CBD, 9-11 weeks total flowering, 400-550g/m² reported. Best indoor or outdoor. easy grow.

Lineage: Ripley's OG Auto traces back to Seedsman's in-house OG program, and the numbers justify the attention — 18–25% THC packed into a cycle that wraps up in 9 to 11 weeks from seed, no light schedule manipulation needed.

Indoors or out, this one pulls 400–550g/m² without demanding much from the grower. The smell runs diesel-forward with a damp, earthy base that gets more pronounced closer to chop. Feeding requirements stay moderate; beginners who've killed a photoperiod from overcomplication tend to do well here because the auto rhythm keeps things moving even when mistakes happen. The high sits heavy without being completely sedating — functional enough for evening use, strong enough that new smokers should start slow at the upper end of that THC range.

Good pick for first-time autoflower growers who want a forgiving plant and a chunky yield without babysitting a light timer.

Growing Ripley's OG Auto

Ripley's 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 9-11 weeks total with yields of 400-550g/m². Plants typically reach 60-120cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. Maintain temperatures between 68-80°F with relative humidity around 45-55% 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Ripley's OG Auto features a diesel, earthy terpene profile that develops complexity throughout the flowering cycle. Pungent fuel and chemical notes hit first, followed by an earthy, musky undertone. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

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.
