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.Here's a bit more about what each product in the pack does: 0-0-1 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.0-0-1 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.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. 0-0-5 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.You can SAVE MONEY with the “mix and match” in our Build-a-Box options.For a list of all Greene County products, here is a link to the other options.Application Information:You will need to water in each of the products in this pack if you apply with a backpack/pump sprayer.
