The shortest version: Mephisto Genetics's take on hybrid genetics, 20-25% THC, 8-10 weeks flowering, easy grow.

Lineage: Buckfast OG comes from Mephisto Genetics, stacking OG Kush heritage into an autoflowering format that finishes in 8–10 weeks from sprout to chop. That's a full cycle you can run indoors or out without worrying about light schedules — particularly useful for Canadian growers squeezing a second outdoor run before temperatures drop below 15°C in September.

THC testing consistently lands between 20–25%, which is meaningful weight for an auto. The smell skews toward citrus peel and fuel, with a softer fruit note underneath that rounds out cured jars nicely. Indoor canopies pulling 400–500 g/m² put this closer to photoperiod returns than most growers expect from an auto, and the low difficulty rating means you're not babysitting it through complicated deficiencies. Keep feeding light early and let the plant tell you when it wants more. A solid pick for newer growers who want genuine potency without the complexity of a full photoperiod grow.

This hybrid-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 Mephisto Genetics, 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 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Buckfast OG Auto delivers THC levels of 20-25%, 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 minutes with a balanced head-and-body experience that evolves over time.

Growing Buckfast OG Auto

Buckfast 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 8-10 weeks with yields of 400-500g/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 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 dense flower formations.

Flavor, Aroma & Terpene Profile

Buckfast OG Auto features a fruity, citrus, diesel terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. 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, Buckfast 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.
