[N-Ext] Build-a-Box (4 Gallon Kit)

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

You all asked for it and we brought it! Mix and match, build your own box of N-Ext Level Fertility.

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 optimize your strategy for the greenest, healthiest lawn on the block.

IMPORTANT SHIPPING INFORMATION: Shipping is included in the price. 

We can not currently ship to Alaska, Hawaii, Oregon and/or PO Boxes

Typically delivered in 4-7 business days.

Free stickers with every order.

When you purchase you'll also receive my N-Ext product guide on when and how much to put down (via email).
