The shortest version: Mephisto Genetics's take on hybrid genetics, 20-25% THC, 8-10 weeks flowering, easy grow.

Lineage: Eiffel 65 comes straight out of the Mephisto Genetics stable, a breeder with a strong reputation for consistent autoflowering performance. At 20–25% THC and a seed-to-harvest window of 8–10 weeks, this one moves fast without demanding much in return — difficulty is rated easy, and it handles both indoor and outdoor runs without complaint, which makes it a solid pick for Canadian growers working with unpredictable shoulder-season weather.

The nose leans fruity and sweet with an earthy base underneath, nothing sharp or polarizing. Indoor growers pulling 400–500 g/m² should see that number land reliably with decent light and a straightforward nutrient program. No light-schedule management required since it flowers on its own clock, so you can drop it into a tent sharing space with other projects and not worry about light leaks or timing conflicts. Good first autoflower for new growers, equally useful as a filler run for experienced cultivators wanting a low-maintenance, high-output plant between bigger photoperiod projects.

Genetics & Lineage

Eiffel 65 Auto traces its genetics to Eiffel 65 (Mephisto Genetics). This hybrid-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 Mephisto Genetics, each seed is selected for genetic stability, terpene expression, and vigor.

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

Eiffel 65 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 minutes with a balanced head-and-body experience that evolves over time.

Growing Eiffel 65 Auto

Eiffel 65 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 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 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

Eiffel 65 Auto features a fruity, sweet, earthy, pine 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, Eiffel 65 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.
