N-Ext RGS is a product containing Humic Acid and Sea Kelp Extract which increases root growth and decreases stress from heat and drought. It comes in a liquid concentrate that you can then spray with a hose end sprayer or mix in a backpack sprayer.
RGS makes it easy to apply humic and sea kelp, it only takes 3 ounces per 1,000 sq. ft to apply so the one purchase will last quite a while.
