Its unique internal structure consists of numerous tiny closed air cells surrounded by a large exterior irregular surface. Expanded Perlite is ultra-lightweight, inert, sterile, permanent, incombustible, asbestos- free, non-toxic, rot and vermin proof and has a neutral pH. Its extremely large, open surface area allows it to retain water in mixes while maintaining air spaces, important for healthy root growth.\u003c\/p\u003e\n\u003cbr\u003eWe use Perlite as part of our Fine Orchid Mix.","brand":"Ravenvision Orchid Supplies","offers":[{"title":"3 litre","offer_id":48198550421669,"sku":"czt1788063168216","price":2.88,"currency_code":"USD","in_stock":true},{"title":"1 litre","offer_id":48198550454437,"sku":"uir1788063168217","price":2.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0711\/1878\/2629\/files\/perlite_1.jpg?v=1788063175","url":"https:\/\/www.evergreenporch.shop\/products\/perlite","provider":"My Store","version":"1.0","type":"link"}
