N-Ext Bio-Stimulant Pack | Four-Gallon RGS, Humic12, MicroGreene and Air-8 Soil Health Kit

Build healthier soil and a stronger lawn with the N-Ext Bio-Stimulant Pack. This four-gallon liquid lawn kit combines four bio-stimulants to improve soil chemistry, stimulate roots, rhizomes, and stolons, and help your grass unlock and use the nutrients already in your soil. One pack covers a 5,000 sq ft lawn for one year.

Often called “Lawn Juju” by Allyn Hane and the DIY lawn community, the Bio-Stim Pack is the starter pack of Greene County’s N-Ext products. It’s the easiest way to get your lawn moving toward healthy, optimized soil that needs very little outside input beyond an occasional dose of fertilizer.

How N-Ext Bio-Stimulants Work

Bio-stimulants support the biological and physical conditions that help turfgrass use available nutrients more effectively. The products in this pack are designed to complement one another by supporting root growth, soil health, micronutrient availability, and water movement through the soil.

RGS uses sea kelp and humic acid to support root development and the growth of stolons and rhizomes. Humic-12 helps improve overall soil health and nutrient availability. MicroGreene provides micronutrients and is especially useful when a soil test identifies micronutrient deficiencies. Air-8 is a liquid aeration product designed to improve water penetration and encourage deeper roots by helping create space in the topsoil profile.
