Made from high-temperature melted basalt fibers, these rockwool cubes provide a sterile, structured environment that supports rapid and healthy root development.\u003c\/p\u003e\n\n\u003cp\u003eThe fibrous composition offers a balanced air-to-water ratio, allowing roots to access both oxygen and moisture efficiently. With high porosity and strong water retention, the cubes maintain consistent hydration while still preventing waterlogging. Each plug includes a pre-formed planting hole for easy seed or cutting placement, making propagation simple and uniform. Their sterile, soil-free design reduces the risk of pests and disease, while their modular structure allows easy transplanting into larger systems such as net pots, soil beds, or hydroponic setups once roots are established.\u003c\/p\u003e\n\n\u003ch5\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cdiv class=\"spec-table-wrapper\"\u003e\n\u003ctable class=\"spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct\u003c\/td\u003e\n\u003ctd\u003eRockwool Grow Cubes (1.6\", 4 Sheets of 112 Plugs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eVivosun\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eBasalt-based rockwool (stone wool fibers)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCube Size\u003c\/td\u003e\n\u003ctd\u003e1.6\" × 1.6\" × 1.6\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Quantity\u003c\/td\u003e\n\u003ctd\u003e448 plugs (4 sheets × 112 plugs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePorosity\u003c\/td\u003e\n\u003ctd\u003eApproximately 95% air-filled structure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Retention\u003c\/td\u003e\n\u003ctd\u003eHigh moisture retention with controlled drainage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSterility\u003c\/td\u003e\n\u003ctd\u003eInorganic and sterile growing medium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUse Cases\u003c\/td\u003e\n\u003ctd\u003eSeed starting, cloning, propagation, hydroponics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransplant Method\u003c\/td\u003e\n\u003ctd\u003eDirect transfer into net pots, soil, or hydro systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRoot Support\u003c\/td\u003e\n\u003ctd\u003ePromotes fast root establishment and oxygen access\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStructure\u003c\/td\u003e\n\u003ctd\u003ePre-formed planting holes for easy insertion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReusability\u003c\/td\u003e\n\u003ctd\u003eSingle-use propagation medium (typically)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage\u003c\/td\u003e\n\u003ctd\u003eDry, compact sheets for easy handling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eSold as-is with no warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReturns\u003c\/td\u003e\n\u003ctd\u003e30-day free returns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"VIVOSUN","offers":[{"title":"Default Title","offer_id":52213461123355,"sku":null,"price":21.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/0151\/0171\/files\/vivosun-16-rockwool-grow-cubes-4-sheets-of-112-plugs-2744822.png?v=1779850756","url":"https:\/\/greenthumbdepot.com\/products\/1-6-rockwool-grow-cubes-4-sheets-of-112-plugs-mp6l3fko-q489j","provider":"Green Thumb Depot","version":"1.0","type":"link"}
