How to get the best results with Allgood Farm Expanded Clay Pebbles
Allgood Farm products are free from pesticides and come in their natural, untreated condition.
<p><strong>Allgood Farm Premium Expanded Clay Pebbles are perfect for hydroponics, soil amendment, decorative pot topping… and so much more!</strong></p> <p>Our large expanded clay (LECA) pebbles are graded 10-16mm, and packaged in carbon-neutral and recyclable plastic bags.</p> <p>LECA is a versatile material widely used in horticulture. To make these pebbles, 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.</p> <p>These large pebbles are ideal for maximum aeration to root balls. Unlike the spherical variety, 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.</p> <p>The irregular shapes also improve water retention and drainage, ensuring your plants receive the right amount of moisture without the risk of waterlogging.</p> <p><strong>Horticulture & Gardening:</strong> mix with soil or potting compost to enhance aeration and drainage. Used to promote vigorous plant growth and reduce the risk of root rot. Expanded clay pebbles also make an attractive pot topper and help reduce surface moulds and invasive insects.</p> <p><strong>Hydroponics & Aquaponics:</strong> expanded clay pebbles are a popular growing medium in both hydroponic and aquaponic systems due to their unique properties and benefits. They help to maintain proper moisture levels, as well as absorbing nutrients for slow release. Their high surface area makes them a perfect home for beneficial microbes which help plants to thrive. Their durability also means they can be sterilised for re-use after every growing cycle.</p> <p><strong>Reptiles, Amphibians & Insects:</strong> as a surface topper in terrariums and vivariums, expanded clay pebbles help to recreate an arid desert look, while maintaining steady humidity. They’re also fully washable and reusable unlike many similar substrates.</p>
