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

Matter-enabled High Quality Light Strips
Size: 9.8ft
Great lights. Used these as accent lights behind an entertainment center to avoid harsh overhead lights. Three in total. They put out plenty of light and easy to install and use. Love the Matter integration. Negatives: can’t use the cut portion. Once it’s cut, the extra is useless. Not cheap for a light strip. Purchase if you like the light tech or want Matter integration. You have to guess for “light temperatures” (warm, daylight, etc.). I used a Google search for finding the Hex # to input into light control and fine tune from there Love these and would buy again

Great product, reliable quality!
Size: 9.8ft, Size: 9.8ft
I moved into a new place with wood stairs. There’s a landing step that is invisible at night - it just looks like the floor below the step. Of course, one can only determine a stair to be invisible at night after one misses said stair, falling, twisting ankle and foot, lying on floor cursing and crying for help from the husband at 11pm in the dark. I used painters tape for a couple of weeks. Again, not so helpful at night but there was some distinction. I knew I needed to light this step up to avoid future slips on the invisible step. I love Govee products. I have a Govee metal tall skinny lamp thing which is where I learned about this gummy, straight, light tube that they make. I really did not want the light strips that were cheaper w the separate little lights on them since this was going under a stair and you could see the underside of the stair clearly from our lower living room whilst sitting on the couch. This product was SUPER easy to install. I love that you can cut it to size (though if you need exact I would go with the Govee light strips w the little lights there’s more cut areas closer together). I love that I already have the Govee app and it connected relatively easily (turning things on/off, using airplane mode and unplugging will get you connected). My 2 gripes about Govee… 1. Please figure out how to make strips that you can cut and connect - I want to be able to configure a corner or different shape besides just a straight line. I also want to be able to connect multiple lines to one adapter (I had a cheap one that could do this but I was afraid it would burn my house down). I paid $$$ for a single step and would like to have been able to use the rest of my strip for another step but instead it’s just useless. 2. I wish it dimmed a little more - the 1% is really bright in the dark. This strip is VERY bright. Anyways, love my step and it’s safe to take the painters tape off and have it be a normal step.

Bright, with great diffuser
Size: 16.4ft
This is a nice, flexible light with a good diffuser. The tape is sticky, so make sure you want this to be permanent, because it's likely to damage wall paint when removed. Lot's of color, pattern, and dynamic light options with the software. My last Govee light strip had the green LEDs burn out after a year, hopefully that's not the case here. I will update this review if that happens. These are pretty pricey, so hopefully they're durable!

Awesome lights just know that they are neon colored and very bright!
Size: 9.8ft
These lights were very easy to install. Very much more flexible than rope lights or even desk lights. They look awesome on my cabinets if I do say so myself….. also know that it wherever you put them is where they’re going to stay… for eternity. Adhesive is so strong that when I had to remove one, I had to use a knife and cut the adhesive off of the actual light itself and leave the adhesive behind or it will tear all the paint off of my wall. It’s a good thing that they’re very strong adhesive wise. Just make sure that you know exactly where you’re putting it and that you have measured properly and if you’re going to cut it, make sure that you do that before you start putting it up. Also, a big deal is that these are neon colored and very bright! If you are trying to match something like dream view, for instance (I did) they will not match with the other lights at all not even close. They don’t even match the desk lights that you see in the video along my countertops. I have to turn the brightness down or it overpower the entire kitchen and other lights.
