The shortest version: Coastal Genetics's take on sativa genetics, 17% THC, 7-9 weeks flowering, easy grow.

Coastal Genetics lists this at $30.17 — below the median of $30.44 across 16 listings. Pack options: 3-seed at $30.17, 5-seed at $44.99, plus larger sizes.

Smell-first, this one announces itself — sharp diesel cut with a sweet finish that lingers longer than you'd expect from a plant that's done in 7–9 weeks. That quick turnaround comes from the autoflower format built on an 80/20 sativa-dominant frame, so you still get the heady, daytime-friendly effect profile at 17% THC without stretching your calendar into the next season.

Coastal Genetics rated this easy to grow, and that tracks — it handles both indoor and outdoor setups without demanding much intervention, pulling around 350g/m² when conditions are reasonable. The mold resistance is a real practical advantage if you're running outdoors in humid stretches or working a coastal microclimate where moisture is a constant problem. Heights stay manageable enough that tent growers won't be fighting their ceiling either.

Good pick for newer growers who want a fast, low-maintenance autoflower that still has a distinct flavor character rather than something generic.

Genetics & Lineage

Diesel Auto traces its genetics to 80% Sativa/20% Indica (Coastal Genetics). This sativa-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 Coastal 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 17%, this provides a mild, approachable experience great for beginners or those seeking gentle relief.

THC Level & Potency

Diesel Auto delivers THC levels of 17%, placing it in the milder range, making it approachable for newer users or those seeking functional effects. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing Diesel Auto

Diesel 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 7-9 weeks with yields of 350g/m2. Plants typically reach 100-160cm 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

Diesel Auto features a diesel, sweet 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, Diesel 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.

Who Should Grow Diesel Auto?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
