Soil amendment

Arrived in a timely manner with a good price. Qualified for free shipping...Always a plus. I could probably use a truck load of these. but spent more than I wanted to. Lowest price I could find. Thanks

First time using

This is the first time using this material in my garden containers and I love it!
The bricks were so much easier to carry than other materials. I love how fluffy it made the raised bed soil as I added it in. I haven?t planted my veggies into it yet but I?m looking forward to having happy plants! I definitely will use again. It also came quickly after ordering!

Awesome product. Best on the market!

I use this product in my reptile enclosures as a bedding and egg laying medium. It's super soft and absorbant and is perfect for this.
I recently trued some as a seed starter for my garden plants and the seeds are loving it. Great root production and strong healthy plants. I will continue to purchase this product for many years. Thanks for being the best.
