Speed Bump

Speed Bump from Common Wealth Seed Co fuses I95 by Top Dawg Genetics with the tropical hash phenom Grape Sunshine to create a chem-forward, grape-tinted hybrid that lives up to its name. Tall and eager to stretch, plants throw massive, densely stacked colas glazed in resin, with colors that deepen as flowers ripen. The nose hits first: sharp Chem and diesel push through sweet grape and citrus, with fuel-laced undertones that linger on the palate. Indoors or out, yields land above average when you rein in early vertical growth, and flowering wraps in roughly 8-10 weeks (about 56-70 days). Expect a balanced 50/50 profile and THC around 22%, with a terpene signature that leans chem, fuel, and bright citrus, nodding to its I95 parent. The onset feels immediate and assertive, an energetic, creative lift that gradually steadies into an uplifted, clear-minded cruise without heavy drag. Grape Sunshine's lineage (Secret Lemon x Tallymon) contributes the tropical candy notes and bulbous, wash-friendly resin, while I95 brings the structure and the classic East Coast chem glare. Bred within the brand's Grape Sunshine line, Speed Bump rewards experienced hands with room to train, yet remains manageable for growers who plan the stretch. If tall vigor, glossy trichomes, and grape-fuel complexity are on your shortlist, this cultivar delivers.
