Amsterdam Blue by Sumo Seeds
Blueberry × Haze
Amsterdam Blue is a sativa-leaning cultivar developed by Sumo Seeds, blending traditional European breeding with modern flavor profiles. It is recognized for its Haze-like vigor and uplifting qualities, balanced by a sweet, approachable berry influence reminiscent of the Blueberry family. This strain is often favored for daytime use, offering a cerebral experience that supports creativity and social engagement.
Appearance
Amsterdam Blue plants are characterized by their sativa-dominant structure, featuring lanky internodes and a tendency for strong lateral branching. Growers may observe a significant stretch post-flowering. In cooler temperatures during late flower, the cultivar can display anthocyanin pigmentation, leading to lavender or slate-blue hues on the leaves and calyx tips.
Aroma & Flavor
The aroma of Amsterdam Blue is often described as clean and zesty, with a resinous finish. Its flavor profile is consistently noted for its clear berry and citrus notes, complemented by floral undertones. The overall profile is perceived as fruit-forward and approachable, with a sweetness that balances the Haze characteristics.
Effects
Consumers report that Amsterdam Blue delivers an energetic and cerebral uplift, often associated with Haze strains, but tempered with a calm and friendly mood lift. This duality makes it suitable for daytime activities, creative endeavors, and social interactions, providing focus without being overly racy. The <1% CBD content suggests a potent THC experience that is generally not sedating.
Terpenes & Cannabinoids
While specific lab results vary, Amsterdam Blue is generally characterized by high THC levels ranging from 15-25% and minimal CBD (<1%). Terpene analysis of similar Blue x Haze crosses often indicates the presence of Limonene and Terpinolene, contributing to its citrus-floral aroma and energizing effects. The overall terpene content typically falls between 1.5-3.0%.
Growing
Amsterdam Blue is considered a sativa-leaning plant with a predictable stretch, requiring ample vertical space and training techniques like SCROG management. It exhibits resilience to common pests when integrated pest management (IPM) is practiced. Flowering times typically extend beyond eight weeks, and the strain can achieve medium-to-high yields. It is well-suited for LED lighting and requires good airflow.
Origins & Lineage
Developed by Sumo Seeds, Amsterdam Blue is a mostly sativa cultivar that draws from Amsterdam's breeding heritage and the influential 'Blue' family. It is believed to be a cross between a Haze-leaning sativa and a Blueberry-type indica, aiming to combine the vigor and psychoactivity of Haze with the sweetness and aromatic appeal of Blueberry. This blend results in a functional, flavorful daytime hybrid.
