<b>[Product Information]</b><br>
<ul>
<li>Perlite is a unique volcanic mineral which expands from four to twenty times its original volume</li>
<li>When expanded, each granular, snow-white particle of perlite is sterile with a neutral ph and contains many tiny, closed cells or bubbles</li>
<li>The surface of each particle is covered with tiny cavities which provide an extremely large surface area</li>
<li>These surfaces hold moisture and nutrients and make them available to plant roots</li>
<li>Perlite is sterile, it is free of disease, seeds and insects</li>
</ul>
