Features

GROW!T horticultural clay pebbles are made from 100% natural clay. They are clean, pH stable, and offer great aeration and drainage in hydroponics, especially in flood and drain, deep water culture, and drip feed systems. Due to their unique structure and ability to cover a large surface area, they offer the ideal environment to foster beneficial bacterial growth around the root zone, leading to naturally healthier plants.

Quality

I used this for deep planters to retain moisture and to provide proper drainage. I put potting soil on top of it.

It works.

walmart.com

So far so good,ph neutral. Make sure to rinse well before using. Other than that,great product at a great price.

This is perfect for my hydroponics system which I am using for the first time this year. The small amount that you have to use does not crush the plant!

Perfect for hydroponics!

Perfect for hydroponics

Shipping was quicker than advertised. Product arrived unharmed. Very happy with the experience.

Great

Great product. Fast shipping, came earlier than expected. Pebbles are not circle like others but work just as great.

Great!

The bad arrived opened, however the weight was correct. The quality of pebbles is bad. They are good enough to be used as a drainage for plants but not in transparent pots. Will use these pebbles but had to buy another better quality.

Acceptable

The bag says the clay pebbles "do not float".  I need it for a pond lily, but when I put the pot in the water, the pebbles all floated out instantly all over the surface of the pond.  
I later tried letting them sit in a (full) sink for a day and a half.  They were still floating.

Not as claimed.   Probably fine if not submerged.

If you are looking for leca to mix in with your soil, or use as a topper, this will meet your needs. But if you are going to use it for semi-hydroponics like I was going to, this stuff is awful. Every single piece floats, even after soaking for over 24 hours. It's completely unusable. What a total waste.

Don't buy it
