Strain Profile
Sour Diesel THCA Flower — commonly abbreviated Sour D — is one of the most legendary sativa-dominant hybrids in the modern catalog, generally credited to the cross of Chemdawg 91 with Super Skunk. The cultivar is a cornerstone genetic responsible for countless modern crosses, with classic long, fluffy buds and an unmistakable diesel-and-citrus aromatic profile.
Effects
Sour Diesel delivers a fast-acting, energizing cerebral high that's been a daytime staple for decades. The lift is sharp and clear-headed — great for productive work, creative tasks, or social settings — while the body baseline stays light and mobile. A reliable, high-velocity sativa cultivar.
Flavor & Aroma
On the palate: pungent diesel up front, with sharp citrus through the middle and a clean herbal finish on the exhale. Smoke is bold and unmistakably classic. The terpene profile reads diesel-citrus-and-skunk — see the COA for the exact terpene breakdown of the current batch.
