Ursa Major

Ursa Major takes its name from the night sky, but its roots are firmly on the ground: Cereal Killer crossed with Jet Fuel Gelato. Selected by Pruf Cultivar as Pruf No. 102, this sativa-leaning hybrid regularly showcases towering potency, with lab results often hovering between 32–38% THC and trace CBD at 0–1%. Open a jar and a rush of citrus and lemon zests leads, chased by cracked black pepper and a savory, spicy-herbal funk. Buds are oversized and fluffy yet well-structured, olive green with thin orange pistils and a dense frosting of milky trichomes that signal the jet-fueled lineage. On the palate, bright lemon and broader citrus ride first, while peppery bite lingers on exhale. The dominant terpene is caryophyllene, supported by limonene and linalool, a trio that frames the strain’s focused, energetic, happy lift. The effect comes on with clean mental clarity, sharpening to-do-list intent without burying the senses, and then settles into a buoyant, upbeat cruise. Growers and reviewers note the variety’s head-forward profile and modern dessert-fuel aroma, while the Gelato heritage adds color and resin density.
