Harle-Tsu blends two CBD icons, Harlequin and Sour Tsunami, into a calm, clear hybrid first crafted by Lawrence Ringo and the Southern Humboldt Seed Collective. This indica-leaning 60/40 cultivar shows short internodal spacing and a sturdy, bushy frame that stays manageable indoors. Its bouquet sits in the earthy citrus pine pocket, led by myrcene and humulene with bright pinene accents, and the flavor follows with clean wood and zest. True to its reputation, Harle-Tsu commonly tests near 1% THC alongside roughly 13 to 20 percent CBD, and famously hit 21.05% CBD at a California competition, underscoring its CBD-first chemistry. Indoors, flowering wraps in 56 to 60 days; outdoors it is ready by early to mid October. Yields are moderate, around 350 g per square meter inside and roughly 450 g per plant outside, rewarding growers with dense, silvery green buds dusted in frost. Effects trend relaxed, focused, and happy without weight, making it a favorite for clear daytime tasks and easy evening decompression. Harle-Tsu also took Best CBD Flower at the Emerald Cup in 2014, cementing its place among modern CBD benchmarks.
