The shortest version: Coastal Genetics's take on indica genetics, 18% THC, 6-7 weeks flowering, moderate grow.

Coastal Genetics lists this at $29.65 — above the median of $28.67 across 25 listings. Pack options: 3-seed at $29.65, 5-seed at $44.99, plus larger sizes.

Lineage: Purple Kush Auto traces back to Coastal Genetics' cookie/cake/runtz crosses, kept at 80% indica to lock in that heavy, sedating lean most pure kush hunters are looking for. The earthy-sweet terpene profile isn't complicated—it smells like damp soil and brown sugar, and the smoke follows through honestly. At 18% THC and a 6–7 week flower window, this one moves fast without sacrificing density; indoor runs have landed right around 450g/m² when light schedules and feeding are dialed in. Plants stay compact enough—60–100cm—that you're not fighting height in a tent or a backyard corner. The autoflowering format means no light-flip management, which cuts one variable out of a moderate grow.

Best suited to evening or nighttime growers chasing genuine body relaxation over a heady, cerebral effect—if you've been disappointed by "kush" strains that felt more sativa-leaning, this one actually holds the indica character it claims.

Genetics & Lineage

Purple Kush Auto traces its genetics to 80% Indica / 20% Sativa (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 18%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Purple Kush Auto delivers THC levels of 18%, 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 Purple Kush Auto

Purple Kush Auto 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 6-7 weeks with yields of 450g/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 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

Purple Kush Auto features a earthy, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. 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, Purple Kush 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.
