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 Phantom OG
Phantom OG is an indica cannabis strain credited to Barney's Farm. Its listed lineage is OG Kush.
Phantom OG THC level
Public listings give Phantom OG a THC level of 18%, which is in the lower third of our dataset. Compared with all strains in our research dataset that have their own THC figure, it is higher than roughly 23% of them. Potency varies by grower, batch and lab, so read these numbers as typical values, not guarantees.
Phantom OG aroma, flavor and terpenes
Its most-reported flavor notes are pine and earthy. The terpenes listed most often are caryophyllene (peppery, spicy), limonene (citrus) and humulene (woody, hoppy). Caryophyllene is the lead terpene for about 24% 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.
Reported effects of Phantom OG
Commonly reported effects: sleepy, relaxed, giggly, happy and euphoric. These are user reports, not promises. Effects differ from person to person and depend on dose, setting and tolerance.
