Petroleum

Petroleum is a sativa-leaning variety (roughly 65% sativa) that brings bold, diesel-forward character to the table. Its lineage traces to a Pure Michigan F2 crossed with Mac, and that genetic mix shows in plants that darken as they mature, become heavily resinous, and carry a sharp, fuel-like aroma—notes often described as rubbery or like a racetrack’s hot asphalt. The overall profile is intense and pungent rather than sweet or floral. Effects tend toward the classic sativa side: cerebral, uplifting, and creatively energizing while still carrying enough physical presence to feel substantial. Expect a clear-headed buzz that motivates activity or socializing more than couch-lock. Because terpene and potency expression can vary, individual runs may lean more energetic or slightly more sedating, but the dominant impression is stimulating and focused. Growing Petroleum rewards vertical space: plants are tall and stretch a lot when switched to flower, so training (topping or low-stress techniques) is recommended to manage height and open the canopy. Flowering runs about 8–10 weeks with medium yields; plants set dense, resin-soaked buds that darken toward harvest. Suitable for growers who want a standout, aromatic sativa that performs well outdoors or in a taller indoor setup with attention to canopy management.
