Product Description:
Frequently touted as “Lawn Joo-Joo” and “Unicorn Pee” by Allyn Hane and other members of the DIY community - these N-Ext products are the real deal. Many of our newly minted Lawn Care Nuts ask what bio-stimulants do, and that’s a great 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.

What is the Yard Mastery Bio-Stimulant Pack?
The Yard Mastery Bio-Stimulant Pack is a four-gallon soil and lawn improvement bundle containing one gallon each of RGS, Humic12, Air-8, and MicroGreene. Together, these products are designed to support root development, improve soil health, increase water penetration, and help turf make better use of available nutrients.
What does each product in the Bio-Stimulant Pack do?
RGS (Root Growth Stimulant) uses sea kelp and humic acid to support roots, stolons, and rhizomes while helping turf handle heat and drought stress. Humic12 contains a high concentration of humic acid to help make nutrients more available to plant roots. Air-8 is a liquid aeration product designed to create space in compacted soil for air, water, and nutrients. MicroGreene supplies micronutrients, potassium, iron, humic acid, and sea kelp to support turf color and growth.
How do you apply the Yard Mastery Bio-Stimulant Pack?
Apply the products according to their individual product labels using a pump sprayer, backpack sprayer, or hose-end sprayer. Each product can be applied during the growing season, and the pack is suitable for many cool-season and warm-season grasses. For personalized application timing and recommendations, use the free Yard Mastery app.
Does the Bio-Stimulant Pack need to be watered in?
Yes. When applying the products with a pump or backpack sprayer, water them into the soil within 24 hours using approximately ¼ inch of rainfall or irrigation. A hose-end sprayer application can count as watering in, although additional irrigation is still helpful. Do not apply more than the label recommends, and follow the instructions for each product.
