Appearance

The dried flowers of Seaweed #3 typically present as medium-dense, often forming elongated, conical colas. The color palette leans towards kelp-green hues, complemented by sea-foam pistils that mature to an apricot or amber shade. Under specific cool-night finishing conditions, faint lavender or slate undertones may appear on the sugar leaves. The buds feature a favorable calyx-to-leaf ratio, indicating efficient trimming and good visual appeal, with robust resin coverage and a frosted appearance.

Aroma & Flavor

The aroma of Seaweed #3 opens with fresh-cut herbs reminiscent of coastal sage and rosemary, intertwined with citrus zest like lime and pomelo, and a subtle cooling lift from eucalyptol. A woody, dry-spicy base, similar to white pepper and cedar, grounds the scent. When gently warmed, a savory, saline nuance emerges, evoking ocean air or kelp, likely due to trace sulfur volatiles. The flavor profile on inhale mirrors the aroma, featuring green, sparkling citrus and savory herbs, with mid-palate notes of peppery wood and hints of green tea. The finish is dry and saline.

Effects

Consumers and growers commonly describe Seaweed #3 as providing a calming sensation. The strain's balanced potency contributes to a refreshing experience, without being overly sedating.

Terpenes & Cannabinoids

While specific lab data is limited, Seaweed #3 is generally characterized as a high-THC, low-CBD hybrid. Estimated total THC content typically ranges from 20% to 26% by dry weight. The terpene profile is complex, with notable contributions from compounds like myrcene, limonene, caryophyllene, linalool, humulene, terpinolene, ocimene, and eucalyptol, contributing to its unique aroma and flavor characteristics. Minor cannabinoids such as CBG and THCV may also be present in modest amounts.

Growing

Seaweed #3 exhibits a lean, upright structure with narrow-to-medium leaflets and moderate internodal stretch during early flowering. Growers report this phenotype as being more stable and uniform compared to siblings, offering predictable growth and a repeatable harvest window. It is considered a connoisseur cultivar, often grown indoors to optimize its terpene expression and resin production.

Origins & Lineage

Seaweed #3 originated from the phenotype-hunting culture of the West Coast in the late 2010s and early 2020s. It was preserved as a keeper cut from a larger Seaweed project, with the '#3' designation indicating the breeder's preferred selection. Its lineage has not been publicly disclosed, but its morphology suggests influences from narrow-leaf varieties. The strain gained popularity through word-of-mouth and private clone exchanges rather than large-scale commercial releases.
