Ultra Sour

Ultra Sour is T.H.Seeds' zesty meeting of two icons: MK Ultra and East Coast Sour Diesel. This sativa-leaning hybrid (about 70% sativa/30% indica) channels ECSD's fuelly spark and MK Ultra's award-stamped pedigree - MK Ultra famously took 1st Indica at the 2003 High Times Cannabis Cup and 2nd in 2004 - into a resinous, medium-to-tall plant that finishes quickly. Indoors, expect 60-66 days of flowering, heights around 140-150 cm, and generous production in the 450-500 g/m2 range given light training and good airflow. The nose is tart and assertive: lemon over classic diesel with a clean sour bite; flavors track the aromatics, settling into a lingering citrus-diesel aftertaste. Typical lab results place THC in the 17-20% window with low CBD, while a terpene trio of limonene, myrcene, and caryophyllene often leads the bouquet. The experience opens with bright, energetic focus and an uplifted, talk-ready headspace, tapering into a calm, centered cruise without heavy couchlock. Buds form in dense, lime-to-olive clusters frosted in trichomes and threaded with tangerine pistils. Bred by T.H.Seeds, Ultra Sour rewards attentive growers and flavor chasers alike with a sharp, modern expression of old-school diesel genetics refined for reliable indoor and outdoor runs. Expect vigorous branching, easy topping, and a tidy stretch that suits SCROG or SOG layouts.
