About Highway Harmony
Highway Harmony, from Karma Genetics, is a hybrid that tests up to 21% THC and takes 8 to 10 weeks to flower, a moderate window on the longer side of average. That combination of solid potency and a fairly patient grow cycle suits growers who aren't in a rush but still want a strong result at the end of it. The name suggests a balanced, easygoing character, one that the flowering window backs up: neither the fastest nor the slowest hybrid on the market, just a steady middle path. For anyone comfortable planning around an 8-to-10-week cycle and chasing a THC ceiling just above the 20% mark, Highway Harmony delivers a dependable target on both counts.
