From the lab panel — 26% THC, <2% CBD. From Canadian grower reports — 400g/m2 yield, fruity/pine dominant in cured flower. moderate grow.

Smell-first: crack a cured jar of Big Smooth and the room shifts toward ripe stone fruit and fresh pine, with a mild sweetness that hangs around longer than you'd expect at 26% THC. Coastal Genetics built this one from proprietary cookie-cake-runtz lineage developed along the California coast, and the mold resistance that came with it translates reasonably well to humid Canadian summers or a greenhouse run where airflow isn't always perfect.

Indoors, growers are pulling around 400 g/m² after an 8–9 week flower, which is a solid return for a strain sitting at moderate difficulty — not a beginner plant, but nothing that demands expert-level dialling. Plants stretch into a manageable canopy, so it fits a standard tent without aggressive training. Works in both controlled indoor environments and outdoor plots in warmer Canadian zones with a long enough season. Best suited to intermediate growers ready to step past autoflowers but not yet chasing finicky, slow-finishing cultivars.

Genetics & Lineage

Big Smooth traces its genetics to Proprietary cross (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 26%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Big Smooth delivers THC levels of 26%, 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 Big Smooth

Big Smooth 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 8-9 weeks with yields of 400g/m2. Plants typically reach 150-220cm 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

Big Smooth features a fruity, pine, sweet 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, Big Smooth 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.
