Genetics

Kritikal Bilbo × Critical Mass

The foundation of this strain is genuine breeding work from Barcelona. Seedstockers crossed elite clones of Kritikal Bilbo from the Basque Country with Critical Mass (Critical+, also known as Critical+) and further refined the line using original Critical Mass seeds from the company’s own genetic archive.

Kritikal Bilbo contributes fast growth, a loud lemon aroma, and high resin production.
Critical Mass / Critical+ provides stability, easy cultivation, massive colas, and the classic Afghan-Skunk influence.

The result is the strongest and most productive Critical version Seedstockers has ever bred: more modern, higher yielding, and more potent than classic Critical strains – while remaining absolutely reliable.

BCN Critical XXL is not a nostalgic throwback, but the modern evolution of a legend.
It delivers. Every time.
