Unlike standard CRF, Poly-S is regulated by microbial diffusion, not temperature. When activated by micro-organisms in the soil, the unique sulfur and polymer coating releases nutrition at an even rate, regardless of climate or temperature swings. The dual coatings also reduce nitrogen leeching and decompose with minimal environmental impact.
Poly-S can be incorporated into growing media or surface-applied in the container. Special Topdress and Quickstart formulations provide an early-season nutrient boost for quick green-up.
