[N-Ext] RGS™ - RGS Stands for Root Growth Stimulant and that’s exactly what it does. This bio stimulant is packed with hormones from sea kelp that stimulate roots and stolons/rhizomes coupled with chelating humic acid.
[N-Ext] RGS™ - Root Growth Stimulant with sea kelp and humic acid is our primary bio-stimulant offering for use in lawns and landscapes. Formulated by John Perry of Greene County Fertilizer Co, RGS is the foundation of all Lawn Care Nut and Yard Mastery programs.
If you are new to spraying liquids on your lawn, this is a great one to start with. It won't "burn" the lawn or anything like that - and RGS is the best to start with anyway since it aids in soil health and stimulates roots in turf.
If you have challenges with your grass holding on during summer heat, getting RGS into the soil will help it through the stress. RGS is truly the backbone of the bio-stimulant program, hands down, and has the highest concentration of sea kelp hormones in the line. It was designed to increase rooting and decrease stress pressure caused by heat and drought. It will also feed microbial life in the soil which helps to optimize your fertilizer treatments.
"N-Ext" is the name of this line of products and N-Ext stands for "Nitrogen Extension." RGS, Root Growth Stimulant, is kind of like the "base layer" of that line because it contains humic acid and sea kelp, the two primary bio-stimulants we recommend. The biologically active material contains humic acid and sea kelp to aid in initial spring green-up, buffer and extend nitrogen release rates, and add oxygen to the soil profile for greater nutrient uptake.
