Sigma 8-5-1 Bio – Large Grade

Sigma 8-5-1 Bio – Large Grade is a biologically enhanced dry fertilizer formulated to deliver strong nitrogen-driven growth while supporting soil health and microbial activity. With an 8-5-1 NPK ratio, this blend is ideal for aggressive vegetative growth, helping plants develop robust structure, lush foliage, and increased biomass.

The large-grade particle size is designed for improved soil aeration and gradual nutrient release, making it well-suited for long-term soil conditioning and outdoor or container applications. As the granules break down over time, they provide a steady nutrient supply while promoting a healthy, active microbial environment.

Formulated with biological inputs, Sigma 8-5-1 Bio supports beneficial microbes that enhance nutrient cycling, improve soil structure, and increase nutrient availability. This results in stronger root systems, improved nutrient uptake, and more resilient plant growth.

Key Features:

• High-nitrogen 8-5-1 NPK formula for vigorous vegetative growth
• Large-grade granules for slow release and improved soil structure
• Supports beneficial microbial activity and soil biology
• Enhances nutrient cycling and long-term soil fertility
• Promotes strong root development and increased plant vigor
• Ideal for soil blending, top dressing, and outdoor/container growing
• Compatible with organic and regenerative cultivation practices

Designed for growers seeking powerful vegetative performance and long-term soil benefits, Sigma 8-5-1 Bio – Large Grade delivers both nutrition and biological support for stronger, more productive plants.
