Lilac Diesel Auto: The Floral Fuel
Lilac Diesel Auto: The Floral Fuel
Strain Overview
Type: Sativa-Leaning Hybrid Autoflower (60% Sativa / 40% Indica)
Breeder: Ethos Genetics (Colin Gordon)
Lineage: Lilac Diesel x Pluto Cut Auto
Market Status: The "Complex Connoisseur"; Lilac Diesel Auto is widely recognized as one of the most terpene-rich autoflowers on the market. While many autos lean on simple fruit or gas profiles, Lilac Diesel Auto offers a sophisticated, layered bouquet that mimics its complex photoperiod mother. It is a "Poly-Hybrid" beast, combining genetics from over a dozen legendary strains (including Super Lemon Haze, Forbidden Fruit, Cherry Pie, and Chem D) into a stable, fast-finishing plant. It is famous for its unique "Floral Gas" aroma and its vibrant, happy high.
THC Content: High (20% – 25%)
Dominant Terpenes: Terpinolene, Caryophyllene, Ocimene, Pinene
Key Effects: Euphoric "Giggles," Creative Energy, Social relaxation, Sensory Enhancement
Lilac Diesel Auto is a bouquet of flowers soaked in gasoline.
It defies the standard "Lemon/Pine/Berry" categories. It smells of fresh lilac bushes, sweet cake batter, tropical fruit, and chemical fuel. It is a loud, pungent plant that produces some of the most photogenic flowers in the auto game—chunky, resinous, and often splashed with pink and purple.
History and Lineage: The Poly-Hybrid Masterpiece
This strain is a genetic marvel, compressing a massive family tree into a single seed.
The Mother (Lilac Diesel): The complex queen. This photoperiod strain is a cross of (Silver Lemon Haze x Forbidden Fruit) x (Cherry Pie x Citral Glue). It was bred specifically to hunt for the rare Terpinolene/Floral trait while maintaining the density and potency of modern cookies/glue strains.
The Father (Pluto Cut Auto): The tank. As detailed in previous reviews, the Pluto Cut Auto is Ethos's heavy-hitting Indica auto donor. It was used here to provide the autoflowering trait, the density, and the heavy gas backbone without erasing the delicate floral notes of the mother.
The Synthesis: Lilac Diesel Auto is a triumph of stabilization. It captures the elusive "Lilac" phenotype—a rare floral terpene expression—and backs it up with the vigor and speed of the Pluto. It is complex, vigorous, and uniquely flavorful.
Terpene Profile: Lilacs, Cake, and Chem
The aroma of Lilac Diesel Auto is sophisticated and distinct. It is often described as "perfume-like" but with a heavy industrial edge.
Dominant Terpenes
Terpinolene (The Floral): The dominant terpene. It provides the signature lilac, apple, and nutmeg aroma. It is responsible for the "Hazy" and "Racy" aspects of the high.
Ocimene (The Sweetness): Highly present. It adds a sweet, woody, and herbal top note that blends with the floral scents to create a "fresh garden" smell.
Caryophyllene (The Gas): The engine. It provides a heavy diesel and black pepper kick that grounds the airy floral notes.
Pinene (The Freshness): Adds a crisp pine sap finish that clears the palate.
Flavor Notes:
The Aroma: It is loud and layered. It smells of blooming lilacs, sweet cake mix, sour cherries, and diesel fuel.
The Smoke: Smooth and complex. It tastes of floral candy and earth on the inhale, with a spicy chemical gas finish on the exhale.
Strain Effects: The Happy Hybrid
Lilac Diesel Auto offers a "Sunshine" high. It is energetic without being anxious, and relaxing without being sleepy.
The Experience
The Spark: The high hits quickly with a rush of creative energy. It wakes up the brain and enhances colors and sounds.
The Giggles: It is a fantastic social strain. It lowers inhibitions and makes everything seem funny. It is the perfect "party weed."
The Cruise: After the initial rush, a comfortable physical relaxation sets in. You feel light and loose, but not heavy.
The Fade: It has a gentle comedown. It doesn't crash you; it just slowly fades into a mellow calm.
Best For: Afternoon parties, creative hobbies (painting/music), concerts, depression, and fatigue.
Growing Lilac Diesel Auto: The Colorful Bush
This strain is a favorite for home growers because it yields well and looks beautiful doing it.
Growth Structure
The Size: Large. It grows aggressively. It forms a large, multi-branched bush that can easily fill a 3x3 footprint if trained.
The Yield: High. It produces massive, chunky colas. It is one of the better yielding autos in the Ethos lineup.
The Colors: Vibrant. In late flower, the buds often turn shades of pink, light purple, and lime green. The bag appeal is elite.
The Speed: It finishes in 80 to 90 days from seed. It takes a bit longer than the fast Indicas, but the yield is worth the wait.
The Feeding: Moderate. It is not a picky eater. Standard nutrient schedules work well.
Grower’s Tip: Lilac Diesel Auto responds very well to LST (Low Stress Training). Tie down the main branches early to open up the center of the plant. Because the buds are large and complex, ensure good airflow to prevent botrytis (mold) in the final weeks.
Similar Strains / Lineage Relations
If you enjoy the profile or growth of Lilac Diesel Auto, you might also appreciate these three genetically related or similar strains:
Lilac Diesel: The Photoperiod Mother.
Why: If you want to clone the genetics or grow a massive outdoor tree with the same flavor, go with the original photoperiod version. It tends to be slightly more stable in its "Lilac" expression.
Pluto Cut Auto: The Father.
Why: If you love the growth structure and density of Lilac Diesel Auto but prefer a darker, heavier, and more sedative high with "Burnt Rubber" flavors, choose the father.
Super Lemon Haze Auto: The Ancestor.
Why: One of the great-grandparents. Choose SLH Auto if you want the Terpinolene/Haze energy but prefer a pure citrus/lemon flavor without the complex floral/cake layers.
Final Verdict: The Floral Fuel
Lilac Diesel Auto is a boutique strain in an automatic package. It proves that autos can be just as complex and flavorful as their photoperiod counterparts. It offers a unique terpene profile that stands out in a sea of generic fruit and gas strains. If you want a plant that smells like a botanical garden and hits like a diesel truck, this is the one to grow.
You should choose Lilac Diesel Auto if:
You love Floral/Cake/Gas flavors.
