The shortest version: Coastal Genetics's take on indica genetics, 19% THC, 7-9 weeks flowering, easy grow.

Lineage: Black Bubba Auto traces back to sun-grown California stock through Coastal Genetics' proprietary program, carrying cookie and cake ancestry that shows up clearly in the dense, resinous structure at harvest. At 19% THC and a sub-2% CBD reading, the effect profile sits firmly in sedative indica territory — this one is built for unwinding, not productivity.

The grow stats make it an easy recommendation for anyone still building confidence with autoflowers. A 7–9 week flower window and roughly 250g/m² under decent light, indoors or out, with genuine mold resistance baked into the lineage from its California outdoor roots. The flavor profile stays earthy and straightforward — nothing tropical or candy-forward here, just clean, dense flower with good bag appeal.

Best suited to beginner and intermediate growers who want a low-maintenance evening-use indica that finishes on a predictable schedule without babysitting.

Genetics & Lineage

Black Bubba Auto traces its genetics to Proprietary cross (Coastal Genetics). 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 Coastal 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 19%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Black Bubba Auto delivers THC levels of 19%, 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 Black Bubba Auto

Black Bubba 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 7-9 weeks with yields of 250g/m2. Plants typically reach 100-160cm 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

Black Bubba Auto features a earthy 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, Black Bubba 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.
