Supreme Diesel
Sour Diesel × OG Kush (possible) × Chem Dawg (possible)
Supreme Diesel is a sativa-leaning hybrid celebrated for its fast-acting cerebral energy and prominent diesel-fuel aroma, often finishing with a sour-citrus note. Commonly testing between 20-25% THC, this cultivar is considered a high-potency option suitable for daytime use.
Appearance
Supreme Diesel plants typically exhibit a medium-tall, sativa-dominant structure with elongated branches. The flowers often form spear-like colas with pointed, fox-tailed calyces, a characteristic common in the Diesel family. Its calyx-to-leaf ratio is favorable, simplifying the trimming process. Mature buds are generally jade to lime-green, accented by rust-colored pistils, and heavily frosted with trichomes.
Aroma & Flavor
The aroma of Supreme Diesel is primarily defined by pungent fuel notes, layered with sour citrus and a subtle mineral tang. Initial scents on the stem-rub include astringent solvent-like qualities, followed by lemon-lime zest and a faint herbal undertone. Some phenotypes may develop a sweet, bakery-like aroma during late flower. The flavor profile mirrors the aroma, offering a distinct sour-citrus finish alongside diesel and earthy notes.
Effects
This sativa-leaning hybrid is sought after for its rapid onset of cerebral energy, typically appearing within 2-5 minutes and peaking around 20-30 minutes. The effects are known to be uplifting and focus-enhancing, providing sensory brightness that lasts for 2-3 hours. While primarily energetic and cerebral, some users report a subsequent sleepy sensation.
Terpenes & Cannabinoids
Supreme Diesel commonly tests between 20-25% THC, positioning it as a high-potency strain. The terpene profile is often anchored by limonene, myrcene, and beta-caryophyllene, with total terpene content ranging from 1.5-3.0% by weight in well-cultivated flower. Other terpenes frequently present include ocimene, humulene, and pinene, contributing to the complex aroma and effects. CBD content is typically less than 1%.
Growing
Growers appreciate Supreme Diesel for its vigorous vertical growth and a high calyx-to-leaf ratio, which aids in trimming. Indoor yields can range from 450-600 g/m², while outdoor plants may produce 600-900 grams per plant in suitable climates. Most phenotypes complete flowering in 63-70 days. The plant responds well to common cultivation techniques like topping and LST.
Origins & Lineage
Emerging from the East Coast Diesel derivatives of the late 1990s and early 2000s, Supreme Diesel is often described as a sativa-dominant hybrid within the Diesel family. While exact origins vary, lineage notes frequently trace it to a Sour Diesel foundation, sometimes stabilized for enhanced fuel aroma and denser buds. Other hypotheses suggest a Diesel cross with an OG Kush or Chem Dawg lineage, aiming to combine the energetic lift of Diesel with a slightly increased body presence.
