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

Really adorable & functional room divider! I love mine!
Color: Dark Coffee, Size: 4 Panel
Really beautiful divider. I use it out on my patio at my apartment building to provide privacy, shade & keep my things safe. At 6 foot tall and 4 panels (I strongly suggest 4 panels) it's quite a lovely addition to my home. It's delicate so handle carefully but it comes completely put together & just set it up. Being able to move it inside or outside or wherever because it's so light makes it very mobile. It's not too opaque you can see through it but if it's for total privacy use a tablecloth or something behind it to make it less see through. It's strong and big and I had a question for their cs and they responded immediately and handled it right away which is a sign of a good company. It's light so make sure you secure it if it's windy for stability.

Nice Look
Color: Dark Coffee, Size: 8 Panel
Attractive and Very versatile. Pretty sturdy, but use care if you buy larger screens when moving. Hinges are small so moving it recklessly could break them. Overall I would recommend this screen. I love it

I Like it...Perfect sunscreen to keep the Sun off me: I Need To Test Outside Durability
Color: Natural, Size: 4 Panel, Color: Natural, Size: 4 Panel
I have Southern exposure on my 6th story balcony. For most of the year, the Sun out there is unbearable. I have had another room divider/sunscreen I have outside in all weather conditions for 9 years...and it has held up well and still going (but showing age). Hoping this one will be as durable. I will update my review after some weather conditions have put it through its paces. The divider is quite attractive and lightweight. It is perfect for what I need it for at this time, and is stable in the wind with the anchoring system I have used.

A wonderful partition to block off the room with gifts
Color: Dark Coffee, Size: 8 Panel, Color: Dark Coffee, Size: 8 Panel
If I could give these 10 stars I would. They are going to be perfect when I use them to close off one of the rooms to hide all of my granddaughter’s birthday presents. They even match my floors.
