Chem Coma

Chem Coma by Black Box Genetics lives up to its name: a ferocious, indica-leaning selection from the GMO x Chem De La Sour lineage, also known as Petrol Station #26. In the garden it stretches into tall, lance-like colas reminiscent of GMO, stacking dense, frost-laden flowers that reward patient growers with high yields. Aromas hit hard and savory—diesel-thick, deeply pungent, and unmistakably chemical—before easing into a meaty, umami funk. Expect a long finish: Chem Coma typically needs 11–13 weeks (about 77–91 days) to fully ripen, but the payoff is substantial. Lab and in-house reports put potency around 30% THC with low CBD, and terpene expression often leans toward caryophyllene, myrcene, and humulene, amplifying the gassy, peppery profile. The experience arrives fast and heavy across the forehead, settling into an enveloping, euphoric calm that leaves many relaxed, happy, and unhurried. Breeder Black Box Genetics names GMO and Chem De La Sour as the parents, the latter channeling the classic Chem/Diesel bite while the former drives yield, stature, and that notorious savory funk. If you can spare the extra weeks, Chem Coma delivers spear-sized colas, big production, and a boldly diesel-forward bouquet that commands attention from first crack of the jar to the last lingering exhale.
