Bio Chem distills classic Colorado breeding into a dense, fuel-forward powerhouse. Created by 303 Seeds, this mostly indica-sativa hybrid pairs Chemdawg #4 with Sensi Star, yielding vigorous plants that carry a 70/30 indica-sativa lean. Aromatics come on loud: heady diesel and zesty citrus over a spicy-herbal, skunky backdrop, driven by a terpene trio of myrcene, limonene, and beta-caryophyllene. Expect compact, resinous flowers flashing lime to forest greens with occasional violet streaks and bright tangerine pistils. Potency lands high, with THC commonly in the 20-25% window and CBD under 1%, translating to an initial lift in mood before a deep, body-heavy calm settles in; many note a contented, sleepy finish. Growers find Bio Chem moderately demanding but rewarding. Indoors it prefers attentive dialing and produces medium yields; outdoors, in full sun, it can bulk up impressively. Flowering typically wraps between day 63 and 77, and the morphology stays manageable - medium height with sturdy lateral branching that stacks dense colas. Flavor mirrors the nose, blending diesel, citrus peel, and peppery herbs into a lingering, savory finish. With Chem 4's edge and Bio-Diesel's heft, Bio Chem honors its lineage while carving its own, unmistakably gassy signature.
