{"product_id":"pumita-piedra-pomez","title":"Pumice stone","description":"\u003cp\u003eImproving drainage and root aeration in heavy substrates where perlite floats to the surface and is crushed in a few cycles, without adding weight to large pots or altering the pH of the medium, requires pumice stone with calibrated granulometry and stable structural density. This pumice —also called \u003cstrong\u003epumice stone\u003c\/strong\u003e, or pumicite— is sold by Gardese in fine (1-3 mm) and medium (3-6 mm) formats in 40 L bags, designed for professional gardening, cultivation of cacti and succulents, hydroponics, improvement of clay soils, and lightweight concrete construction.\u003c\/p\u003e\n\n\u003ch3\u003eMain benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuperior aeration with low compaction:\u003c\/strong\u003e the porous cellular structure ensures continuous oxygenation of roots and prevents root asphyxiation in Caribbean clay soils, a critical condition for cacti, succulents, and sensitive plants.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStructural density that does not float:\u003c\/strong\u003e unlike ultralight perlite that rises to the surface after several waterings and loses its function, pumice maintains a stable position in the substrate for years, it does not crush or compact.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeutral pH, chemically inert:\u003c\/strong\u003e it does not alter the acidity of the substrate or react with fertilizers or chemical additives, a condition compatible with all types of mixtures for gardening and agricultural production.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal insulation for the root zone:\u003c\/strong\u003e low thermal conductivity protects roots from temperature spikes in pots exposed to the Caribbean sun.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual use in gardening and construction:\u003c\/strong\u003e applicable as an aggregate for lightweight concrete, low-density blocks, and wall insulation, expanding its use beyond horticultural substrate.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical applications and uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMix with base substrate (topsoil, coco fiber, peat moss) for pots and planters: 20-40% for horticultural and ornamental plants, up to 50% for cacti and succulents.\u003c\/li\u003e\n  \u003cli\u003eHydroponic cultivation with pumice as an inert support medium in recirculating systems.\u003c\/li\u003e\n  \u003cli\u003eRecovery of compacted clay soils in lawns, orchards, and professional gardening.\u003c\/li\u003e\n  \u003cli\u003eDrainage layer at the bottom of pots and as an aggregate for lightweight concrete in light construction.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and durability\u003c\/h3\u003e\n\u003cp\u003eAn economical pumice fails in two ways: the granulometry is irregular with high proportions of fine dust (which reduces useful volume and produces uneven drainage when settled) and the volcanic origin is not controlled (which produces stones with high impurities that affect the pH of the substrate). Gardese works with pumice calibrated in selected fine or medium granulometry, which separates a professional gardening and construction pumice stone from a generic bag that saturates the pot with dust.\u003c\/p\u003e\n\n\u003cdiv style=\"background-color: #F3F6F3; padding: clamp(14px, 4vw, 18px); margin-top: 20px; font-size: 0.9em; color: #555555; border-radius: 8px;\"\u003e\n  \u003cstrong style=\"color: #006902;\"\u003eAlso known as:\u003c\/strong\u003e\n  \u003cstrong\u003eTechnical:\u003c\/strong\u003e pumice stone, pumicite, pumice, pumice stone, pumicite aggregate, lightweight volcanic substrate.\n  \u003cstrong\u003eIn DR and Caribbean:\u003c\/strong\u003e piedra pómez, pumita, piedra liviana volcánica.\n  \u003cstrong\u003eIn other countries:\u003c\/strong\u003e pumice (USA), pumice stone (USA), piedra pómez (LATAM), agricultural pumice (USA), tepetate ligero (MX), pumicita (ES).\n\u003c\/div\u003e","brand":"GARDESE","offers":[{"title":"Fine [1 - 3 mm (0.04 - 0.12 in)] \/ 40 L (10.6 gal) bag","offer_id":52483381854536,"sku":"921341","price":9000.0,"currency_code":"DOP","in_stock":false},{"title":"Medium [3 - 6 mm (0.12 - 0.24 in)] \/ 40 L (10.6 gal) bag","offer_id":52254405755208,"sku":"472834","price":9000.0,"currency_code":"DOP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/9751\/2776\/files\/piedra-pomez-pumita-drenaje-macetas-santo-domingo.png?v=1771869190","url":"https:\/\/dodom.com\/en\/products\/pumice-stone","provider":"Dodom","version":"1.0","type":"link"}
