Sour 78 is a documented cannabis cultivar in the Strain Encyclopedia. It is listed with the parent cross OG 78 HIGH CBD × Head Band x Sour Diesel) Indica / Sativa: 50% CBD/ 5 % Indica / 45% Sativa.
About
Sour 78 is a balanced hybrid cannabis strain bred from OG 78 HIGH CBD crossed with a Headband and Sour Diesel hybrid. The resulting genetic profile sits at approximately 50% CBD, 45% Sativa, and 5% Indica, making it one of the more CBD-dominant crosses to carry recognizable legacy genetics on its Sativa side. The lineage is straightforward and purposeful: OG 78 HIGH CBD brings the cannabinoid profile down from typical THC-forward territory, while the Headband and Sour Diesel pairing contributes the Sativa character and terpene complexity that experienced cultivators will recognize immediately.
Given the Sour Diesel and Headband parentage, the aroma and flavor profile of Sour 78 trends toward the fuel-forward, pungent end of the spectrum. Expect sharp diesel notes with an underlying earthiness, likely accented by the cerebral, slightly chemical brightness that Headband consistently passes to its offspring. The Sour Diesel influence in particular tends to produce robust terpene expression, so growers should anticipate a crop that announces itself early in flower.
Commonly reported experiences with high-CBD, Sativa-leaning strains like this one include a clear-headed, functional quality — users frequently describe a sense of calm without significant sedation, along with mental ease that does not interfere with day-to-day activity. The minimal Indica percentage suggests the body component is present but restrained, and the dominant CBD content typically moderates the intensity of any psychoactive response.
Grow notes specific to Sour 78 are not extensively documented in the available data, but the genetic background offers useful inference. Sour Diesel-derived genetics are known to run vigorous and stretchy, particularly in the early flowering phase, so growers working in limited vertical space should plan accordingly. The OG 78 HIGH CBD lineage may contribute some structural stability, but topping and training are likely advisable to manage canopy height. No specific flowering time, yield figures, or environmental preferences are confirmed for this variety at this time.
From a breeding standpoint, Sour 78 represents a meaningful intersection of high-CBD production and well-established Sativa flavor genetics. Its cannabinoid ratio makes it a candidate parent for breeders looking to introduce CBD dominance into crosses without sacrificing the aromatic complexity that Sour Diesel and Headband lineages reliably deliver.
