## Description

You will receive a custom amount of Hydroton IE: 4 Liters, 6 Liters, 8 Liters or 13 Liter depending on what you order a plain plastic bag. It will not be in retail packaging as we fill the bags from larger 50L Bags which are also available. The original Giant Hydroton brand expanded clay is a unique, lightweight expanded clay aggregate made in Germany. This natural clay is mined, formed into pellets, then kiln fired at high temperatures to cause the clay to expand into tough, lightweight balls. Clay naturally has balanced capillary action, with an ideal surface structure. Hydroton brand expanded clay is semi-porous and generally does not float like other products can. For best results, rinse all expanded clay before use. It is reusable as long as it is thoroughly cleaned between uses. 50 liter bags feature an easy pour spout. Giant size Hydroton is also available with a size specification of 15-25 mm.

## Customer Reviews

### ⭐⭐⭐⭐⭐ literally giants
*by H***B on September 26, 2017*

Compared to regular size these are quite big. Floats. Good product overall.

### ⭐⭐⭐⭐ A Little Doesn't Go A Lon Way
*by D***S on May 3, 2018*

These pebbles were used as a substrate for my shelf liners for my orchids. They were perfectly for this purpose and look really nice on the shelf. Only issue I have with this product is the price for what you get. A 4L bag was only enough to fill up one liner and a add a few pebbles to another. Not really worth the price in my opinion for that purpose. The liners are about 35in long and 14in wide.

### ⭐ FALSE ADVERTISING!!!
*by A***R on July 14, 2020*

We received our order today and there were a few problems. The first is the pebbles are NOT what the seller claimed: They are tiny (not giant) pebbles. Secondly, they were contained in a hap-hazard Ziploc bag with no label. This seems fishy to me - Waiting to hear back from the seller to see if we can actually get what is advertised.
