The shortest version: Blimburn Seeds's take on indica genetics, 20-25% THC, 8-10 weeks flowering, moderate grow.

Smell-first impressions matter when you're trimming a tent at 2 a.m., and this one hits with layered citrus and sweet fruit before you even get to the jar. Purple Sunset Auto from Blimburn Seeds runs 8–10 weeks flower-to-harvest and has tested between 20–25% THC across multiple phenotypes, so you're not gambling on potency with a compact autoflower. Plants top out around 60–100cm, which keeps things manageable whether you're running a 4x4 indoors or tucking a few pots onto a balcony. Yields land in the 400–500g/m² range under solid light and consistent feeding — respectable numbers for an auto without needing a dialed-in environment to get there. Blimburn built this one to finish fast without thinning out the terpene load, and it mostly delivers on that. Difficulty sits at moderate, meaning beginners can run it but shouldn't skip the VPD homework.

Best suited for intermediate growers who want a quick-cycling indica-dominant auto with real fragrance and enough potency to justify the run.

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 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Purple Sunset Auto delivers THC levels of 20-25%, 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 Sunset Auto

Purple Sunset 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 8-10 weeks with yields of 400-500g/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 Sunset Auto features a fruity, citrus, sweet, earthy 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, Purple Sunset 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.
