Appearance

CBD #1 Bx2 presents a mostly indica structure with medium height and stout branching. Its leaves are broad, often lime to forest green, with plants typically reaching 0.8–1.2 meters indoors. The flowers are compact and dense, forming stacked colas with substantial resin production despite low THC levels.

The plant features a high calyx-to-leaf ratio, simplifying the trimming process. Buds tend to be rounded, resisting breakage during harvest and drying. Cooler night temperatures may induce anthocyanin blushes in the foliage.

Aroma & Flavor

The aroma is characterized by a citrus-herbal profile with warm, peppery undertones. Primary notes include lemon zest and sweet florals, complemented by crushed herbs and a hint of fresh wood. Late-flower development can deepen the aroma to resemble lightly honeyed herbal tea.

On the palate, CBD #1 Bx2 offers a lemon-herbal taste with a smooth, lightly sweet finish. Initial impressions are of fresh citrus peel, followed by soft florals and a subtle pepperiness. The exhale is gentle and tea-like, especially when properly cured.

Effects

This cultivar is designed for clarity-forward effects, often described as focused. While specific effects can vary, the low THC and higher CBD content generally contribute to a smoother experience.

Terpenes & Cannabinoids

CBD #1 Bx2 is engineered as a Chemotype III plant, meaning it is CBD-dominant with low THC. While exact percentages vary, stabilized CBD lines often show total CBD in the 10-18% range and low total THC. Key terpenes contributing to its profile include Myrcene, Limonene, Caryophyllene, Linalool, Pinene, and Humulene.

Growing

With its mostly indica heritage, CBD #1 Bx2 exhibits manageable indoor and outdoor performance. It is noted for short-to-medium flowering times and a compact, grower-friendly structure.

The strain is adaptable to various cultivation environments, including tents and small rooms. Its high calyx-to-leaf ratio and rounded bud structure contribute to an efficient and straightforward growing process.

Origins & Lineage

Developed by ACE Seeds, CBD #1 Bx2 is the result of two generations of backcrossing to an elite CBD #1 parent. This breeding strategy aims to stabilize desirable traits, particularly a high CBD to THC ratio, consistent plant structure, and terpene balance.

ACE Seeds, founded in 2003, is known for preserving and improving heirloom genetics. The Bx2 designation signifies the increased genetic uniformity achieved through backcrossing, making it valuable for consistent chemotype expression critical in CBD projects.
