About Romulan Haze

This sativa-dominant cross of Romulan and Haze is known for its potent THC range, spanning from 19% to 34%. The version offered by Next Generation Seeds presents a spicy flavor profile and is considered a difficult grow, requiring a long flowering window of 10 to 12 weeks. Indoors, the plants reach 100 to 150cm and yield between 400 and 500 g/m², while outdoor plants can tower up to 220cm. Despite its height and sativa leanings, the primary effect is deeply relaxing. The terpene profile is rich in linalool and pinene, adding to the complexity of its spicy notes. Because of its difficult grow rating and long maturation time, it presents a unique challenge for cultivators who can manage its significant outdoor height. Outdoor yields are more modest, ranging from 113 to 170 grams per plant. This 70% sativa variety offers a specialized experience for those seeking high potency and a calm, relaxed state.
