The shortest version: Coastal Genetics's take on hybrid genetics, 18% THC, 7-9 weeks flowering, easy grow.

Smell-first impressions matter when you're selecting an auto, and this one opens with ripe grape layered over damp soil and a clean sweetness that lingers longer than most fruity varieties. Killer Grape Auto is a Coastal Genetics proprietary cross sitting at 18% THC — enough potency for focused daytime use without the ceiling that heavier autos sometimes carry. It wraps up in 7–9 weeks from sprout to chop, and indoor runs average around 300 g/m², which is honest production for a plant this low-maintenance.

The difficulty rating is easy, and that holds up in practice — this one handles light stress and minor environmental swings without drama. It runs well indoors or out, so growers working a greenhouse or a backyard plot both get a workable option. If you've been burned by finicky autos that stall in suboptimal conditions, this is a reasonable next pick.

Genetics & Lineage

Killer Grape Auto traces its genetics to Proprietary cross (Coastal Genetics). 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 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

Killer Grape 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 minutes with a balanced head-and-body experience that evolves over time.

Growing Killer Grape Auto

Killer Grape 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 300g/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

Killer Grape Auto features a fruity, earthy, 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, Killer Grape 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.
