Allgood Farm Expanded Clay Gravel is a grey-brown decorative aggregate which also makes one of the key ingredients in many of our specialist soil mixes.

Expanded clay, known as LECA (Lightweight Expanded Clay Aggregate) is highly porous, with a large surface area. This allows it to absorb water and nutrients and slowly release them back into the soil (or water, in hydroponic setups).

Since it won’t break down in soil, this gravel provides long-lasting structure and can be re-used time after time.

This medium grade LECA works well to provide extra drainage and aeration in soils for succulents and epiphytes.

How to get the best results with Allgood Farm Expanded Clay Gravel

Allgood Farm products are free from pesticides and come in their natural, untreated condition.

Allgood Farm LECA Medium Clay Pebbles are a lightweight and porous aggregate, ideal for adding to soil mixes or hydroponics systems, or as an attractive pot topper. Expanded clay pebbles (known as LECA – lightweight expanded clay aggregates) are a versatile material widely used in horticulture. To make them, high quality raw clay is rolled into pellets, then fired in a kiln, causing the pellets to expand and become extremely lightweight, whilst also being durable. Unlike perfectly spherical clay pebbles, our irregularly shaped expanded clay pebbles offer superior performance by creating more surface area and improving aeration. This unique structure enhances root oxygenation, leading to healthier plants and higher yields. The irregular shapes also improve water retention and drainage, ensuring your plants receive the right amount of moisture without the risk of waterlogging. Our medium clay pebbles are also ideal as a washable and reusable substrate for reptile vivariums. We particularly love these pebbles as a pot-topper for our succulents – but they’re so versatile we can’t wait to see how you’ll use them!

 Verified The bag with the soil was packed in a cardboard box and arrived in perfect condition. I .have purchased this Mediterranean soil mix before and it is an outstanding product. I have used it with olive trees and lavender and wouldn't think of using anything else. I think it is very reasonable value. A reliable seller from whom I am always happy to buy.
