Why this one matters: indica genetics with a 21-26% THC ceiling and earthy/diesel-led terps. 9-10 weeks flowering, indoor or outdoor.

Lineage: Permanent Marker Auto traces back to the same cut that made the photoperiod version a fixture in North American grow rooms — now stabilized into an autoflowering format that finishes in 9–10 weeks from seed. THC tests consistently land in the 21–26% range, which is a meaningful ceiling for an auto, and the yield potential of 500 g/m² indoors holds up when growers dial in light schedules around 18–20 hours during the Canadian shoulder seasons.

The nose is blunt: fuel and damp earth, not fruit salad. If you've grown earthy indicas before and appreciated that profile, this one doesn't stray from it. Difficulty is rated easy, and the autoflowering structure means no light-dep management — a practical advantage for basement setups or short outdoor windows in provinces like Alberta or Manitoba. Best suited to intermediate growers who want a high-THC auto without babysitting a complicated feed schedule.

Genetics & Lineage

Permanent Marker Auto traces its genetics to -title">. 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 Zamnesia Seeds, 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 26%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Permanent Marker Auto delivers THC levels of 21-26%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. 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 Permanent Marker Auto

Permanent Marker 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 with yields of 500 g/m². Plants typically reach 100 cm 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

Permanent Marker Auto features a earthy, diesel terpene profile that develops complexity throughout the flowering cycle. Pungent fuel and chemical notes hit first, followed by an earthy, musky undertone. 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, Permanent Marker 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.
