Spec sheet first — strain: hybrid, seed type: autoflower, THC: 20-25%, yield band: medium, environment: indoor or outdoor.

Smell-first: crack the jar on a cured Grape Crush bud and the grape-candy note hits before anything else, followed by a slow diesel exhale that lingers on the back of the palate. That flavor profile carries straight through from flower to finished smoke, which isn't always a given with autoflowers. Mephisto bred this one to finish in 8–10 weeks from seed with no light-schedule management required, so indoor and outdoor growers both run it the same way. Tested at 20–25% THC, it's on the stronger end for an auto, with effects that lean relaxed without turning sedative mid-afternoon.

Yields land around 400–500 g/m² under decent light, and the difficulty rating is genuinely beginner-friendly — compact structure, forgiving feeding window, no fussing over photoperiod triggers. If you're newer to growing your own under the Cannabis Act personal-cultivation rules and want a high-THC auto that actually tastes like something, this is a reasonable first run.

THC Level & Potency

Mephisto's Grape Crush Auto delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable.

Growing Mephisto's Grape Crush Auto

Mephisto's Grape Crush 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

Mephisto's Grape Crush Auto features a fruity, diesel, sweet, earthy 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, Mephisto's Grape Crush 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.
