Source Haze is a documented cannabis cultivar in the Strain Encyclopedia. It is listed with the parent cross Mango Haze #5 × Face Off #4 × Uncirculated OG × Pure Thai.
About
Source Haze is a hybrid cannabis strain bred from a complex four-way cross involving Uncirculated OG, Mango Haze #5, Pure Thai, and Face Off #4. This lineage brings together a notably diverse genetic foundation — pairing the resinous, fuel-driven character of OG and Face Off #4 stock with the tropical, elongated structure associated with Mango Haze #5 and the sharp, energetic qualities long attributed to Pure Thai. The result is a strain that sits at a genuine crossroads of indica influence and sativa heritage, with neither side fully dominating the other.
The aroma and flavor profile of Source Haze reflects the tension in its genetics. Expect the kind of layered nose that comes from combining OG-derived earthiness and fuel notes with the bright, fruity lift that Mango Haze #5 contributes. The Pure Thai influence often pushes things toward a sharper, more herbal or spiced quality on the back end, keeping the profile from reading as straightforwardly tropical. The overall impression is complex rather than clean — a strain that reveals different layers depending on cure and phenotype expression.
Commonly reported effects lean toward mental clarity and engagement in the early stages, consistent with the sativa-leaning portions of the cross, particularly the Thai and Mango Haze contributions. Users frequently describe an uplifted, focused quality followed by a more grounded physical ease as the session progresses, reflecting the OG and Face Off #4 influence working in the background.
From a cultivation standpoint, the genetics suggest a plant that will show meaningful phenotypic variation. Mango Haze #5 and Pure Thai ancestry can push toward longer flowering windows and stretchier structure, while the OG and Face Off #4 lines typically contribute more compact node spacing and heavier resin production. Growers selecting from Source Haze seed stock should expect to hunt phenotypes, as the gap between expressions within a single run can be substantial. Plants expressing more Thai or Haze dominance will likely require more vertical space and a longer finish.
In terms of breeding significance, Source Haze represents a thoughtful convergence of four distinct genetic traditions, making it a useful candidate for further crosses where both terpene complexity and structural diversity are desirable traits in the offspring.
