The specs in one line: 18-24% THC, <1% CBD, 10-11 weeks total flowering, 400-500g/m² reported. Best indoor or outdoor. easy grow.

Lineage: Dutch Passion's long-running Xtreme Haze line, reworked into autoflower format without gutting the sativa character that made the original worth growing. At 18–24% THC, this one sits well above the typical auto range, and the floral-earthy nose is noticeably more complex than most fast-finishing varieties. The 10–11 week seed-to-harvest window fits neatly into a Canadian patio season or a year-round tent run — no light-schedule management required. Indoor growers pulling 400–500 g/m² should expect dense, resinous canopies that benefit from some airflow planning once buds start stacking in week seven or eight. Difficulty is rated easy, which holds true as long as you don't overcrowd the pot; the sativa structure wants lateral room to branch.

A solid pick for growers who gave up on long-season haze plants after a short outdoor window cut their last run short.

Effects & Experience

Users report primarily euphoric and relaxed effects, making this strain ideal for evening use and unwinding after a long day.

With THC levels reaching 24%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Auto Xtreme Haze delivers THC levels of 18-24%, 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 Auto Xtreme Haze

Auto Xtreme Haze 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 10-11 weeks total with yields of 400-500g/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 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

Auto Xtreme Haze features a floral, earthy terpene profile that develops complexity throughout the flowering cycle. The complex aromatic bouquet develops fully after proper curing. 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, Auto Xtreme Haze 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.
