Quick read: 20-25% THC, 60-100cm mature height, 8-10 weeks bloom. Genetics: School of Rock (Mephisto Genetics). Difficulty: easy.

Lineage: Rock Lotus × Sour Stomper, both longtime fixtures in Mephisto Genetics' autoflower program. That pairing pushes THC into the 20–25% range while keeping the grow manageable enough for first-timers — no light-schedule juggling, no fussing over transition cycles. Indoor runs typically land between 400–500g/m², and the whole cycle wraps in 8–10 weeks from sprout to harvest.

The nose leans fruity upfront, then shifts into diesel with a faint floral finish that catches you off guard in a good way. Effects sit on the relaxed-but-clear side — the kind of high that's functional rather than flooring. Both indoor and outdoor growers can run this without issue; the compact frame handles either setup without complaint. If you want a high-THC auto that doesn't punish newer growers with finicky feeding windows or tricky environmental demands, School of Rock is a reasonable first choice.

THC Level & Potency

School of Rock Auto delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable.

Growing School of Rock Auto

School of Rock 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

School of Rock Auto features a fruity, diesel, floral 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, School of Rock 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.
