[N-Ext] Bio-Stimulant Pack has four products that supercharge your lawn growth, improve soil chemistry, and stimulate roots, rhizomes, and/or stolons in your grass.
In the Bio-Stimulant Pack, you’ll get 4-Gallons in four 1 gallon bottles
This pack, loaded with humic, kelp, and micronutrients PLUS liquid aeration.
Frequently touted as “Lawn Joo-Joo” and “Unicorn Pee” by myself and other members of the Lawn Care Nut community - these N-Ext products are the real deal. Many of our newly minted Lawn Care Nuts ask, what do bio-stimulants do, and that’s a good question.
This combo pack optimizes and unlocks nutrients in the soil so that your turf roots can pull out more naturally existing soil nutrients. At the same time, this will help you create an ecosystem that self-sustains cohesively and needs very little outside input other than the occasional dusting of nutrients.
The Bio-Stim Pack is the "starter pack" of N-Ext products designed to get you moving on the right track towards more healthy, optimized soil.
[N-Ext] RGS Stands for Root Growth Stimulant and that’s exactly what it does. This biostimulant is packed with hormones from sea kelp that stimulate roots and stolons/rhizomes coupled with chelating humic acid.
N-Ext Humic12™ is one of the primary bio-stimulants used to improve overall soil health. The 12% concentration in this product is much higher than most currently available to DIYers.
N-Ext 0-0-2 MicroGreene™ is a micronutrient fertilizer with humic and sea kelp. If you have a soil test showing micronutrient deficiencies then this is your go-to product to get your levels moving in the right direction.
N-Ext Air-8™ Liquid Aeration is designed to create space in the soil, increase water penetration, and encourage deeper rooting to drive more oxygen into the topsoil profile.
