1/50 Limited Release Boxes Produced.
Sour Diesel “A-Cut” X Fire on the Mountain (FOTM = Sour Diesel “A” × Chem Fuego)
98.82125% Pure Sour Diesel.
Uncle Doobie’s Sour Diesel BX5.5 is the final result of five full breeding runs of backcrossing carried out over a period of five years, all centered around the most revered Sour Diesel ever circulated: the Sour Diesel “A” Cut. This is the cut unanimously recognized by the Chem family, the original Sour circle, and every East Coast OG as the end-all, be-all expression of real Sour Diesel.
By pairing this legendary A-Cut with Fire on the Mountain — itself a fusion of Sour Diesel “A” and Chem Fuego — Doobie pushed the line into a razor-pure 98.82% Sour Diesel expression. Expect blistering fuel, sharp citrus, penetrating chem, and that unmistakable Sour focus that made the A-Cut the gold standard.
This is the same A-Cut that powered Doobie’s back-to-back 1st place wins in 2025, further validating its status as the definitive Sour Diesel of the modern era.
Produced in a limited run of 1 of 50 boxes, Sour Diesel BX5.5 stands as a true collector-grade, historically accurate Diesel artifact — built for cultivators and breeders who demand nothing less than the truest Sour expression ever released.
