N-Ext Air-8™ Liquid Aeration is designed to create space in the soil, increase water penetration, and encourage deeper rooting to drive more oxygen into the topsoil profile.

  • One gallon covers up to 21,300 sq ft
  • Analysis is 0-0-5::N-P-K
  • Contains 8% Humic Acid
  • Great for hard compacted soil
  • Available in multiple sizes*

Product Description:
Air-8 Liquid Aeration dives down into the soil, breaking bonds between molecules, which creates space. Every bond that is broken creates more space (aka greater soil surface area) where grassroots can then spread and grow.

This also pulls down moisture and carbon since humic acid is included in the mix. If you have hard, compacted clay soil, Air-8 liquid lawn aeration is an excellent alternative to the butt-kicking you get from mechanical aeration.

One thing we know: 95% of homeowners cannot or will not rent a mechanical aeration machine. It's quite the hassle even to go and get it, especially if you don't have a truck to get it home in. On top of that, it's quite the workout. Since so many people are not able to mechanically aerate, liquid lawn aeration is your next best choice.

Now, we do still recommend mechanical aeration as a way to make a good seedbed if you are doing an overseeding. Poking all those holes really does help keep everything from washing away. Plus, running an aerator is a butt-kicking that everyone needs to experience at least once in their life! However, if you are not seeding, then just spray down Air-8, and you will get great results and never need to rent an aerator again.

It is a good idea to water the lawn the night before you apply and then again after your application, water it in with ½” of irrigation or rainfall. The more soil moisture present before and after application, the more effective liquid Air-8 will be.

Solid Kids Sandals, Overpriced Like Most Kids Shoes 🌞
Size: 11 Little Kid, Color: Brown, Size: 11 Little Kid, Color: Brown
My son hasn’t worn these yet since it’s December in Indiana and sandals + snow obviously don’t mix. 😂 So this review is based on first impressions rather than long term wear. That said, these seem wider than a lot of typical kids’ sandals, which I REALLY appreciate since we tend to have wider feet in our family. #hobbitfeet The quality feels pretty decent overall. They’re described as lightweight, and while they’re not insanely lightweight, they do have enough weight to feel semi-sturdy and not flimsy or cheap. I like the style and color, and I think they’ll work well for my son once warmer weather hits. My main complaint is the price. At just under $24 at the time of this review, it feels a little high for kids’ sandals and for what these are. I really feel like $20 MAX would make more sense. Kids shoes are almost always priced like adult shoes, even though they clearly use less material, and that’s hard for me to understand and wrap my mind around. Overall, these seem solid for daily wear, I just wish the price was a bit more reasonable and affordable.

Great basic and timeless design
Size: 12 Little Kid, Color: Brown
These sandals are a great find! They’re super easy to get on and off thanks to the Velcro straps, which is a huge win for little ones learning to be more independent. The fit is adjustable and secure, so they stay in place well during all kinds of play. The cork-style footbed is comfortable and gives good support, and the overall design feels sturdy enough to handle everyday wear. They’re lightweight but still durable, and have held up really well so far. They also have a classic, versatile look that goes with just about everything, perfect for summer outfits. Overall, a reliable, comfortable sandal that’s great for active kids. Would definitely buy again!

Great option for boys or girls
Size: 13 Little Kid, Color: Black, Size: 13 Little Kid, Color: Black
This is really more of a unisex option for a sandal. I have sandals that look like this, and both of my children have worn this style. I ordered these for my daughter, with the plan to pass them down to my son if they're not too worn when she outgrows them. The style is very minimalistic, so it goes with lots of outfits. All the straps are easily adjustable, so you can get a good fit. I would say the length is true to size, but the width is maybe a bit wide. Nevertheless, the adjustable straps really help them fit well. They feel really sturdy and I appreciate that the sole has cushion to it. My daughter has worn these every day since I got them out of the closet and they're holding up well.
