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.

Great
Color: 1 Pro White
This new pro-level paddle is an absolute revelation, truly earning its five-star rating. My control instantly improved; dinks became effortless and drops landed precisely where I aimed them. The textured surface generates incredible spin, allowing for shots with wicked curve and dive. Power is readily available, transforming drives into piercing rockets across the court. Even during extended rallies, its balanced feel and quick handling keep me agile at the net. The sweet spot is incredibly generous, providing surprising forgiveness on less-than-perfect contact. It feels remarkably durable, shrugging off aggressive play without a scratch. This paddle doesn't just play well; it feels like a natural extension of my own hand, elevating my entire game. Seriously, if you're looking to upgrade your performance, this is the paddle you need.

I got this pickleball paddle set for my husband and I to try and learn how to play this new popular sport. My first impressions of the rackets are they have a nice, solid feel to them but without feeling heavy. So solid yet lightweight would be an accurate description I think. After playing several rounds with my husband the grip still felt comfortable. Oh and I like the sling bag that comes with it. The bag is big enough to hold all the pickleball essentials. I noticed when we were practicing that the rackets seem to be responsive and easy to control. The rackets are constructed of fiberglass and polypropylene and I have not noticed any issues with them so far everything is intact just like new. It also comes with a few balls to get started. I would compare them to whiffle balls as they are very similar in shape and size. I am happy with my purchase of this outdoor pickleball set. It is a good value for the price, and a good starting point for beginners.

Love them
Color: Sunrise
Love the color of these and they’re great quality. Got as a gift for my niece who had expressed interest in starting to play pickleball so really loved the design of this set. Thought they are very reasonably priced for the high build quality and she's commented on how lightweight the rackets are yet very strong. Think this is a great stater set and would recommend.

Good quality at a great price!
Color: Blue
The box included everything mentioned. The Paddle feel light, and has enough power to smash. The grip is very comfortable too. The included "outdoor balls" feel lighter than what I'm used to, but worked well on a windy day. Great for beginners. It would make an excellent gift for a novice or intermediate player.
