Sigma 2-4-2 Bio - Large Grade Sigma 2-4-2 Bio - Large Grade is a biologically enhanced dry fertilizer formulated to support root development, flowering, and overall plant health. With a 2-4-2 NPK ratio, this blend emphasizes phosphorus and potassium to promote strong root systems, improved flowering performance, and enhanced plant structure. The large-grade granules are designed for slow, controlled nutrient release, making this product ideal for extended feeding cycles in soil-based systems. Its coarse texture helps improve soil aeration and drainage, reducing compaction and supporting a healthier root zone environment. Enhanced with biological inputs, Sigma 2-4-2 Bio encourages beneficial microbial activity that improves nutrient cycling and availability. This results in stronger root establishment, better nutrient uptake, and improved plant resilience during critical growth phases such as transplanting and early flowering.
