Auto Fuel by Purple City Genetics
Chem × OG Kush × Sour Diesel × Autoflower Donor (unspecified)
Auto Fuel is an autoflowering hybrid developed by Purple City Genetics, emphasizing a potent "gas" or diesel aroma profile. This cultivar aims to deliver the speed and convenience of an autoflower with the high-impact characteristics of classic fuel-forward strains.
Appearance
Auto Fuel typically grows to a medium indoor height, often between 70-110 cm. It develops a strong central cola with secondary buds, featuring dense, resinous, and often spear-shaped flowers. The calyx-to-leaf ratio is favorable, simplifying the trimming process. Buds are covered in abundant trichomes, giving them a silvery appearance as they mature. Coloration ranges from lime to forest green, with pistils maturing from cream to orange or copper. Cooler temperatures late in flower may induce subtle anthocyanin expression.
Aroma & Flavor
The dominant aroma of Auto Fuel is strongly "gas," characterized by notes of petrol, kerosene, and rubber, detectable even during mid-flower. Secondary aromas include lemon cleaner, citrus zest, black pepper, and warm spice, with potential hints of pine and eucalyptus. As the plant matures, a tarry sweetness emerges beneath the fuel notes. Upon curing, the sharp lemon-fuel aroma can mellow into a smoother diesel character with possible cocoa or coffee undertones.
On inhale, Auto Fuel presents a bright, solventy lemon-diesel flavor, often described as reminiscent of lighter fluid. This is followed by deeper, earthy accents. The exhale carries notes of peppered spice, tarry sweetness, and a lingering diesel aftertaste.
Effects
Auto Fuel is known for providing high-impact effects, aligning with the potency seen in modern autoflowering varieties. The experience is described as long-lasting and potentially intense, making it more suitable for experienced users. It offers firmly relaxing physical effects that may appeal to medical users.
Terpenes & Cannabinoids
This strain typically tests between 20-25% THC, with CBD levels below 1%. Prominent terpenes contributing to its aroma and flavor profile include Myrcene, Limonene, Caryophyllene, Pinene, and Humulene. These terpenes are responsible for the characteristic fuel, citrus, peppery, and earthy notes.
Growing
Auto Fuel is an autoflowering strain, meaning it will flower automatically regardless of light cycle. It is generally considered suitable for indoor cultivation, particularly in Sea-of-Green (SOG) setups, due to its medium stature and strong apical dominance. The strain exhibits vigorous root development and a fast onset of bloom. Yields are reported to be in the range of 350-550 g/m² indoors or 60-120 g per plant. Outdoor yields can range from 80-150 g per plant in favorable climates over a 70-85 day period from germination.
Origins & Lineage
Developed by Purple City Genetics, Auto Fuel is an autoflowering cultivar designed to capture contemporary West Coast "gas" and diesel flavor profiles. While a precise pedigree is not publicly detailed, its characteristics strongly suggest a lineage involving classic fuel-forward genetics like Chem, OG Kush, or Sour Diesel, crossed with a robust autoflower donor. The breeding process involves stabilizing the recessive autoflowering trait and fixing the desired terpene signature over multiple generations.
