Sigma 7-2-1 Bio – Large Grade

Sigma 7-2-1 Bio – Large Grade is a biologically enhanced dry fertilizer designed to support strong vegetative growth while improving soil health and long-term fertility. With a 7-2-1 NPK ratio, this formulation delivers elevated nitrogen levels to promote vigorous foliage development, structural strength, and overall plant vigor.

The large-grade granules are engineered for slow, controlled nutrient release, making them ideal for extended feeding cycles in soil-based systems. This coarse texture also helps improve soil aeration and drainage, supporting healthier root zones and reducing compaction in containers and field applications.

Enhanced with biological inputs, Sigma 7-2-1 Bio promotes beneficial microbial activity that improves nutrient cycling, increases nutrient availability, and supports a more balanced soil ecosystem. This results in stronger root systems, improved nutrient uptake, and more resilient plant growth.

Key Features:

• 7-2-1 NPK formula for strong vegetative growth and plant development
• Large-grade granules for slow-release feeding and soil conditioning
• Supports beneficial microbial activity and soil biology
• Enhances nutrient cycling and long-term soil fertility
• Improves soil aeration, drainage, and root zone health
• Ideal for soil blending, top dressing, and outdoor/container growing
• Compatible with organic and regenerative cultivation practices

Designed for sustained performance and healthier soils, Sigma 7-2-1 Bio – Large Grade provides reliable nutrition and biological support for vigorous, high-performing plants.
