Grow facts come from the breeder first, then seed banks and strain databases. With 2 sources we show the range and the middle; with 3 or more, the range and the median, after leaving out values far from the rest. The breeder's own value is the anchor, unless it is far from every other source (outside their range and more than 20% from their median); then we show the full range and the median of all of them. A fact from a single source is marked "1 source", and a fact no source lists is left out. Yields are converted to one unit: indoor per square meter, outdoor per plant.
CTU writes every profile from these facts; we do not copy other sites' descriptions. Values that are a generic default in the source data are left out. Last checked Oct 21, 2026.
Source: CTU strain dataset (public strain listings and breeder info, checked by CTU), verified Oct 2026. Potency, flavor and effects vary by grower, batch and plant. Facts no source lists are left out.

About Sour Power
In public strain data, Sour Power is classed as a hybrid attributed to HortiLab Seeds. Public lineage data lists it as a cross of ECSD and StarBud.
Sour Power THC level
Public listings give Sour Power a THC level of 19%, which is below most strains we track. Compared with all strains in our research dataset that have their own THC figure, it is higher than roughly 30% of them. Potency varies by grower, batch and lab, so read these numbers as typical values, not guarantees.
What does Sour Power smell and taste like?
Its most-reported flavor notes are skunk, diesel and berry. The terpenes listed most often are limonene (citrus), caryophyllene (peppery, spicy) and linalool (floral, lavender-like). Limonene is the lead terpene for about 21% of the high-confidence strains in our dataset, so it is a less common lead. Terpenes shape smell and taste; their levels change from batch to batch.
