Product Description:

RGS is a root growth stimulant with sea kelp and humic acid is our primary bio-stimulant offering for use in lawns and landscapes. Formulated by John Perry of Greene County Fertilizer Co, RGS is the foundation of all Lawn Care Nut and Yard Mastery programs. 

If you are new to spraying liquids on your lawn, this is a great one to start with. It won't "burn" the lawn, or anything like that - and RGS is the best to start with anyway since it aids in soil health and stimulates roots in turf.

If you have challenges with your grass holding on during summer heat, getting RGS into the soil will help it through the stress. RGS is truly the backbone of the bio-stimulant program, hands down, and has the highest concentration of sea kelp hormones in the line. It was designed to increase rooting and decrease stress pressure caused by heat and drought. It will also feed microbial life in the soil which helps to optimize your fertilizer treatments.

"N-Ext" is the name of this line of products, and N-Ext stands for "Nitrogen Extension." RGS, Root Growth Stimulant, is kind of like the "base layer" of that line because it contains humic acid and sea kelp, the two primary bio-stimulants we recommend. The biologically active material contains humic acid and sea kelp to aid in initial spring green-up, buffer and extend nitrogen release rates, and add oxygen to the soil profile for greater nutrient uptake.

  • 1 Single Quart (32 oz) = covers up to 10,650 sq ft

Amazing
Format: Kindle
I have read books 1 - 4 of conversations with God and I am speechless. At first I was skeptical could God really speak to us so freely? But after reading and putting into practice what has been taught through these books I too am having conversations with God. How amazing is that!

Incredible book!!
Format: Kindle
August 16, 2025 I confess that I have not yet read conversations 1,2 or 3 but this one caught my eye so I started reading. Very great book! I enjoyed the chapters on light and on giving, I really appreciate the candidness of Father God, it got me when he said “I’m not asking you to take care of EVERY homeless person… what I am asking you to do is to take care of one!” Father God then continued “if you take away one thing from this book… give to the homeless, buy them a meal, buy them a drink and give them some money. Ask them how their day is going today and just treat them like human beings! When you ignore them, it is like you are ignoring my son Jesus!” So good! I also love how father God said: “we are not asking you to do the impossible, just obey the commands and the teachings of my son Jesus, just be the light and love people” and I love how the Father delved into the details! I hope that this review helps and I’ll be reading 7 keys to be intimate with Jesus soon. Amen! Thank you Father & thank you Matthew Robert for writing this and God bless you sir if you read this review 👍🏿

State of the Art Book!
This book was recommended to me by my graduate school professor as being the most up-to-date, most inclusive book on trauma therapy that exists today, and that it is! First, it is written in an organized and coherent manner. It is extraordinarily well written and engaging which is amazing for a text of this type. It contains information on just about every subject that a beginning trauma therapist as well as a well-seasoned therapist would want to know! This is an incredible book and my only criticism is that, knowing how much I shall be referring to it, it is only a paperback and I wish it were a hardcover so that it will withstand the test of time in better condition. The price is extraordinarily reasonable when one considers the cost of most textbooks these days. I highly, highly recommend this book as a MUST read for every trauma therapist, or trauma therapist in training. I cannot say enough excellent things about the Briere and Scott text. Buy it. You will not regret it for a moment! In addition, after purchasing the DSM-V, I can say that although this book was written before the DSM-V came out, it dovetails with it extremely well, and is a perfect book to purchase after getting the new DSM-V if you don't already have Principles of Trauma Therapy. It is for anyone who is a mandated reporter also, as I am. Presently, I'm a doctoral candidate in Special Education, and find that this book will be helpful there as well. As a person who has worked directly in Special Education for over 11 years, and have had professional contact with Special Needs children for over thirty years, this book is a must--for anyone who works with children, teens, (or adults who have just disclosed trauma) whether you are in Psychology or Special Education, or any allied field that makes you a mandated reporter. The book is a MUST HAVE.

Excellent book for students trying to grasp PTSD
As a professor teaching post traumatic stress reaction to graduate and undergraduate students, I was looking for a book that hit the basics along with some key pieces regarding assessment, diagnostic criteria, and examples that highlighted some of the subtleties associated with complex trauma. This book is well organized and not too overwhelming for people new and beginning the field and a nice refresher for seasoned clinicians. Easy to read, clearly outlined to build upon each subject, I found it both a solid read, affordable, and made it a required read for my course. Please note that I purchased this book way back October 12, 2013 but only now getting to put my thoughts in writing.
