Coastal Genetics runs this as a hybrid feminized line — 25% THC lab range, diesel/earthy-dominant terps, 9-10 weeks from flip.

Lineage: OG Kush crossed with Sour Diesel, sun-grown along the California coast by Coastal Genetics — and that ancestry shows up clearly in both the nose and the grow. At 25% THC across feminized cuts, this one sits toward the stronger end of what a moderate-difficulty plant tends to produce, which makes dialling in your feed schedule worth the extra attention. Indoors or out, growers can expect roughly 450 g/m² after a 9–10 week flower, with a terpene profile that skews sharply toward fuel and damp soil rather than anything fruity or sweet.

The 50/50 indica-sativa split means structure lands somewhere in the middle — not the sprawling sativa canopy that needs constant training, but not a compact indica either. Topping early and giving it room to breathe will serve you better than letting it run free. Best suited to intermediate growers comfortable adjusting nutrients mid-flower and working in controlled indoor setups or stable outdoor climates.

Genetics & Lineage

Sour OG traces its genetics to 50% Indica/50% Sativa (Coastal Genetics). This hybrid-dominant feminized 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 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Sour OG delivers THC levels of 25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. 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 Sour OG

Sour OG is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 9-10 weeks with yields of 450g/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 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

Sour OG 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.

Medical Benefits

While individual experiences vary, Sour OG 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.

Who Should Grow Sour OG?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
