Made from high-temperature processed basalt fibers, these grow cubes provide a stable, moisture-retentive rooting environment that supports fast germination and vigorous early root development.\u003c\/p\u003e \u003cp\u003eWith a highly porous structure, the cubes maintain an ideal balance of air and water retention, allowing roots to receive consistent oxygen while absorbing moisture and nutrients efficiently. Each cube includes a pre-formed planting hole for easy seed or cutting placement, and the sheet can be separated into individual cubes for transplanting into hydroponic systems, soil, or net pots. Suitable for both hobby and commercial growing applications, these rockwool cubes offer clean, uniform propagation support across a wide range of plant types.\u003c\/p\u003e \u003ch5\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h5\u003e \u003cdiv class=\"spec-table-wrapper\"\u003e \u003ctable class=\"spec-table\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eProduct\u003c\/td\u003e \u003ctd\u003eRockwool Grow Cubes Starter Sheet\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBrand\u003c\/td\u003e \u003ctd\u003eVivosun\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCube Size\u003c\/td\u003e \u003ctd\u003e1.6″ × 1.6″ × 1.6″\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePack Quantity\u003c\/td\u003e \u003ctd\u003e1 sheet \/ 28 plugs\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMaterial\u003c\/td\u003e \u003ctd\u003eHigh-temperature processed basalt fiber (rockwool)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eStructure\u003c\/td\u003e \u003ctd\u003eHigh-porosity fibrous propagation medium\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePorosity\u003c\/td\u003e \u003ctd\u003eApprox. 95% air porosity\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFunction\u003c\/td\u003e \u003ctd\u003eSeed germination, cloning, propagation, hydroponic rooting\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWater Retention\u003c\/td\u003e \u003ctd\u003eHigh moisture retention with strong aeration\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePlanting Design\u003c\/td\u003e \u003ctd\u003ePre-formed seed insertion hole in each cube\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eTransplanting\u003c\/td\u003e \u003ctd\u003eEasy cube separation and transfer into grow systems\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCompatibility\u003c\/td\u003e \u003ctd\u003eHydroponics, net pots, soil systems, propagation trays\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCleanliness\u003c\/td\u003e \u003ctd\u003eSterile and inorganic growing medium\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eUse Cases\u003c\/td\u003e \u003ctd\u003eSeed starting, cuttings, cloning, commercial and hobby growing\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e","brand":"VIVOSUN","offers":[{"title":"Default Title","offer_id":52213458436379,"sku":null,"price":7.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/0151\/0171\/files\/vivosun-16-rockwool-grow-cubes-1-sheet-of-28-plugs-5491669.png?v=1779850809","url":"https:\/\/greenthumbdepot.com\/products\/1-6-rockwool-grow-cubes-1-sheet-of-28-plugs-mp6l08gl-rmc22","provider":"Green Thumb Depot","version":"1.0","type":"link"}
