The shortest version: Barney's Farm's take on indica genetics, 18-22% THC, 9-10 weeks total flowering, easy grow.

Barney's Farm lists this at $26.37 — below the median of $35.96 across 24 listings. Pack options: 3-seed at $26.37, 5-seed at $40.10, plus larger sizes.

Smell-first: crack a jar of Purple Punch Auto and the room fills with grape candy, ripe berry, and a faint floral note that lingers longer than you'd expect from an autoflower. Barney's Farm built this one by crossing Purple Punch with their BF Auto Critical, and the result is a compact indica auto that finishes in 9–10 weeks from seed — no light schedule changes, no fuss.

Indoors, growers are pulling 400–550g/m² from plants that stay manageable in height, and THC typically tests between 18–22%, which puts it firmly in the "you'll feel it" range without being overwhelming. Difficulty is rated easy, so it works in tent grows, spare rooms, or outdoor spots with a decent summer. Effects lean physical and settled — good for winding down rather than staying sharp. Recommended for newer growers who want a reliable, resin-heavy indica auto without babysitting a photoperiod plant through a full season.

Genetics & Lineage

Purple Punch Auto traces its genetics to Crossing Purple Punch with our monster BF Auto Critical created our amzing Purpl. 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 Barney's Farm, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy 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 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Purple Punch Auto delivers THC levels of 18-22%, 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 Punch Auto

Purple Punch 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 9-10 weeks total with yields of 400-550g/m2. Plants typically reach 60-120cm 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 Punch Auto features a fruity, sweet, floral 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 Punch 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.
