ACE Seeds Description

CBD #1 Bx2 (Cannatonic Line) is the result of a second backcross designed to further stabilize one of the most sought-after high-CBD chemotypes on the market. This line was created by backcrossing the already stabilized CBD #1 (selected for consistently high CBD and very low THC) with an elite Cannatonic S1 mother expressing up to 25% CBD.

The Bx2 generation represents a decisive step toward fixing the original high-CBD Cannatonic S1 genotype. Due to its increased level of inbreeding, Bx2 is slightly less vigorous and productive than the classic CBD #1 from the main catalog, but it offers superior chemotype stability, making it an exceptional IBL for high-CBD breeding projects.

This variety stands out for its very high CBD content, minimal THC levels, refined terpene profile, and high-quality resin production. Its genetic stability, consistency, and cannabinoid profile position it as one of the most valuable inbred lines currently available for breeders focused on CBD-dominant genetics.
