TH Seeds Watermelon Ultra

Genetic Composition

Watermelon Ultra seeds by TH Seeds are a limited-edition hybrid combining a terpene-rich Watermelon mother with MK-Ultra, the renowned Cannabis Cup-winning cultivar with G13 heritage. The result is a 60% Sativa and 40% Indica hybrid offering distinctive watermelon and Kush genetics. Only 710 special packs were produced, adding to its rarity and collectibility.

Growth Characteristics

Watermelon Ultra seeds produce tall, bushy plants reaching approximately 120 to 160 cm, with strong branching and balanced internodal spacing. The relatively open structure promotes airflow and light penetration, while early resin development leads to dense, heavily trichome-coated flowers. Flowering takes approximately 8 to 9 weeks, with yields ranging from 450 to 600 grams per square meter under optimal conditions.

Aroma and Flavor

Watermelon Ultra delivers a distinctive terpene profile combining juicy watermelon with spicy, kushy, and earthy notes. A fresh eucalyptus-like character adds another layer to the aroma. The flavor follows the same profile, blending sweet and spicy watermelon with earthy Kush undertones and a cool herbal finish.

Cultivation and Yield

Watermelon Ultra seeds perform well indoors and outdoors and respond effectively to topping and other training techniques. Its manageable structure, early resin production, and dense flowers make it suitable for growers interested in both flower and concentrate production. With a relatively short 8- to 9-week flowering period and yields up to 600 grams per square meter, it offers a productive cultivation cycle.

Why Choose Watermelon Ultra Seeds

Watermelon Ultra seeds combine unique Watermelon and MK-Ultra genetics with manageable growth, strong yields, and exceptional resin production. Its spicy watermelon, Kush, and eucalyptus-inspired terpene profile, along with its limited 710-pack release, makes Watermelon Ultra a distinctive choice for collectors and growers seeking rare TH Seeds genetics.
