Refined for premium performance
From extraction to refinement to application, Granubor’s quality is unmatched.
Composition: Unlike ulexite, Granubor comes from a highly pure, calcium free tincal ore found at our Boron, California mine.
Refinement: Our ore is fully refined, ensuring no impurities are introduced and maximizing plant uptake of boron. In contrast, ulexite is minimally processed, meaning contaminants remain.
