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.

Love!
Size: 10, Color: Sailors Red
The quality is excellent. They are more of a faded red. I ordered a 10 worried they might be snug but that was a mistake. I should have stuck with my normal size 8. (I purchased an Amazon brand of this style that runs small and the size 10 feels more like an 8.) I love the length-not too short and not too long. They are sturdy cotton. There is not any stretch to the fabric. I’m giving them to a friend. I actually tried to shrink them by washing them in hot water and hot dryer but it didn’t make them fit me any better. Since they were already too big, I can’t really say if they shrunk by doing this. They weren’t huge on me before washing and seemed to fit the same way after. I tried wearing them all day and they seemed to loosen up even further. I was continuously pulling them up. I really feel like the sizing is accurate and you can be pretty confident of ordering your regular size. I’ve already reordered the size 8. I’ll update my review if there any issues with that size.

Unattractive but well made
Size: 4, Color: Sand
The style was unflattering overall. The shorts fit well in the waist, legs, and seat; they just made me look masculine which is not the look I was going for. For reference I am 5’7, 135#, and purchased a size 4 (which again, fit me well). I’m not sure if the issue was the length, or maybe they just down have a flattering cut - they are very boxy and hide any curves I have. 3 stars because the fit was good and they are well made. But just not attractive.

Nice design Size runs big
Size: 4, Color: Nautical Navy
The size 4 runs kinda big. It’s a very relaxed fit. I’m 5’8” 140 lbs and I need a belt to keep the size 4 up. Very nice fabric, great cut. I’m happy with them just didn’t expect them to be as baggy.

Stretch out, size down but love the shorts.
Size: 8, Color: Ocean Breeze
Love these shorts. My favorites ever. I always always wear a size 8 in shorts. The 8 fit initially, but stretched out so much, I didn’t have to unbutton them to get them out. I bought 3 colors. I finally bought one in a size 6. Perfect fit, even if they do stretch a little. Returning the unworn ones, and replacing with size 6.
