!!PLEASE MAKE YOUR SELECTION WISELY. ONCE YOUR ORDER IS PLACED PRODUCTS CANNOT BE EDITED, MODIFIED, or SWAPPED!!

This combo pack is a customizable mix-and-match. Build your own box of N-Ext Fertilizer products.

Mix and match 4 - 1 gallons

The idea is for you to make your own custom bio-stimulant strategies, but also offer you flexibility should you only need to refill certain products. I tend to run out of RGS and MicroGreene most often but I also like the FloraGreene for my trees and shrubs. Having this kind of flexibility to order Greene County products really allows you to optimize your strategy for the greenest, healthiest lawn on the block.
