This is 2-gallons in two 1 gallon bottles
1 Gallon of N-Ext 7-0-0 Greene Effect
1 Gallon of N-Ext 0-0-2 MicroGreene
This is the famous iron combo that you've heard about, now available in a convenient 2-gallon pack. This is the fastest and most economical way to turn your lawn double dark blue-green and keep it that way for 4-6 weeks. With this combo, you get green through the shoots and more green through the roots - double dark! Look for results in a few days and watch it get darker and darker over the following weeks.
N-Ext 7-0-0 Greene EfFect™ combines nitrogen and iron uniquely to give you a greener lawn, without a growth push. 7-0-0 Greene EfFect™ can be absorbed directly into grass leaf tissue, which brings a faster green-up.
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.

We recommend you apply this via a pump sprayer or battery sprayer and use a tip that delivers a smaller (finer) droplet size.
Fill the sprayer halfway with water first (important).
