Product Description:

RGS™ - 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.

Best possible option out there!
Color: Large - Obsidian Oasis
Fits like normal sock for me. I'm a guy.... Fits like ankle sock I got large. I wear size 9.5 to 10 USA show size. How that helps. It fits just like a normal ankle sock doesn't restrict or press on your toes like others. Woke up this morning and my feet don't look like all peely they are normal looking now so that's good I guess? They work.

Gel socks
Color: Purple Paradise
These feel really weird to put on but once they warm up a bit they’re not bad for just laying around and relaxing. Definitely be careful walking around in case they slip against your foot. I’m not really sure I felt any softening or moisture difference from the oils supposedly embedded in the gel, but they do give your feet a bit of humidity which I guess helps when they start sweating lol. I wear a size 8 in women’s shoes and they felt like they could still be stretched much larger, but if you’re just laying down they don’t need to be snug. If you have anything smaller than a 7 they will definitely be long and floppy. The purple color is pretty and they are soft on the outside. I’m not sure about durability yet since I haven’t washed them yet but they are hand wash only so I expect they would last a while if you don’t over stretch or damage the gel inside. They seem to be constructed fine, the socks aren’t coming apart or unraveling at all, I’m sure the gel helps the soft fibers stay together as well

Great moisturizer socks
Color: Purple Paradise
My feet are so crazy dry. I shave off the skin prickles and sand down the rest every week. I put these on for maybe 30 minutes and my feet already feel better!
