4DD

4DD is a Chem-on-Chem-on-Chem indica bred by People Under The Stairs Genetics by crossing Chem D with a hybrid of Chem Dog #4 and Chem IBL. This lineage keeps the strain firmly rooted in old-school Chem territory, defined by pungent fuel and chemical funk, complemented by earthy herbs, pepper, and a sour citrus finish. The flavor profile mirrors the aroma, prioritizing diesel and chemical intensity over the sweetness common in many contemporary hybrids. While user reports are limited, the experience is generally described as beginning with an upbeat, euphoric onset that transitions into a heavier, more sedative body effect. Beyond its use as flower, 4DD is recognized as a breeding tool, having been used to create progeny such as Chem Cake, Dawg Breath, Banana BreaDD, and ChemheaDD OG.
