Product Description:

RGS is our flagship bio-stimulant for lawns and landscapes, combining the benefits of sea kelp and humic acid in one powerful formula. Developed by John Perry of Greene County Fertilizer Co., RGS serves as the foundation of all Lawn Care Nut and Yard Mastery programs.

If you're new to applying liquid treatments to your lawn, RGS is the perfect starting point. It won't burn your grass, and it delivers immediate benefits by improving soil health and stimulating root growth.

Struggling with grass that weakens under summer heat? RGS helps your lawn push through stress by building stronger, deeper roots. With the highest concentration of sea kelp hormones in the N-Ext line, it was specifically formulated to enhance rooting, reduce heat and drought stress, and nourish the soil's microbial life — helping you get the most out of your fertilizer applications.

The N-Ext product line — short for "Nitrogen Extension" — is built around RGS as its cornerstone product. Its biologically active blend of humic acid and sea kelp supports early spring green-up, buffers and extends nitrogen release, and improves soil oxygenation for enhanced nutrient uptake.
