The specs in one line: 18% THC, <2% CBD, 7-9 weeks flowering, 250g/m2 reported. Best indoor or outdoor. easy grow.

Smell-first, this one announces itself before the jar is even open — a thick layer of grape candy cut through with old-school skunk that sits on your fingers long after the trim. Grape Inferno Auto pulls those flavors from Mendocino Farms' proprietary NorCal cross (Mendo Breath, Headband, and Trainwreck in the background), and they carry cleanly into the smoke without tasting synthetic.

At 18% THC and a 7–9 week flower cycle, it fits neatly into a balcony run or a small tent without demanding much from the grower — difficulty is rated easy, and yields around 250 g/m² are realistic under decent light. The plant stays compact enough that height isn't a problem in tight Canadian grow rooms, and the autoflower format means you're not chasing light schedules through a short summer window. A good pick for newer growers who want a recognizable flavour profile without babysitting a finicky phenotype.

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.

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

Grape Inferno Auto delivers THC levels of 18%, placing it in the moderate-to-strong range that most regular consumers find comfortable.

Growing Grape Inferno Auto

Grape Inferno 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 250g/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 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

Grape Inferno Auto features a fruity, skunky 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, Grape Inferno 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.
