This rockwool is crafted from natural ingredients, including 60 percent basalt, 20 percent coke, 20 percent limestone, and a trace of iron slag. Through high temperature melting, spinning into fine fibers, and a unique compression process, the material becomes durable yet open to air and moisture as your plants grow. The result is a reliable plug that supports steady growth while staying easy to handle during propagation.\u003c\/p\u003e\u003ch3\u003eWhy these cubes stand out\u003c\/h3\u003e\u003cp\u003ePractical benefits you can expect to notice in the grow space include the following features that translate into real-world performance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eThe 95 percent porosity delivers ample oxygen to roots, helping seedlings establish quickly and steadily.\u003c\/li\u003e\n\u003cli\u003eHigh permeability supports a robust root system, creating a solid foundation for eventual transplantation.\u003c\/li\u003e\n\u003cli\u003eInorganic and sterile composition minimizes the risk of fungal issues and keeps the propagation medium clean between uses.\u003c\/li\u003e\n\u003cli\u003eStrong water retention helps maintain hydration and nutrient access between top-ups, reducing daily maintenance.\u003c\/li\u003e\n\u003cli\u003eLightweight and easy to cut to size, with a preformed hole for seeds or cuttings and a flat profile that makes monitoring growth straightforward.\u003c\/li\u003e\n\u003cli\u003ePack contents include 2 sheets of rockwool, 50 cubes per sheet, totaling 100 plugs, each at the convenient 1 inch size.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow this works in real use\u003c\/h3\u003e\u003cp\u003eIn practice, growers seed directly into the preformed holes, then watch for root emergence through the medium. When roots are ready, the cube can be transferred into your preferred growing medium with minimal disturbance, reducing transplant shock and speeding up setup for new plants.\u003c\/p\u003e\u003cp\u003eAcross hydroponics, propagation, cloning, and seed starting, these cubes simplify workflows. The flat, uniform plugs enable quick visual checks of growth progress and easy scaling of propagation without soil mess or substrate inconsistency.\u003c\/p\u003e\u003ch3\u003ePack contents and practical tips\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePack contents: 2 sheets of rockwool, 50 cubes per sheet, for a total of 100 plugs.\u003c\/li\u003e\n\u003cli\u003eSize: 1 inch cubes with a preformed hole for seeds or cuttings, suited for standard propagation trays.\u003c\/li\u003e\n\u003cli\u003eUsage tip: Keep the cubes consistently moist but avoid overwatering to maintain an even moisture balance for early roots.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNote that outcomes vary with environmental factors such as light, temperature, and nutrient management. The material is designed to support typical propagation workflows and is not a guarantee of results, but many growers report smoother early root development and faster establishment in compatible systems.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What are VIVOSUN 1-Inch Rockwool Cubes best used for?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Ideal for hydroponics, seed starting, cloning, and propagation, offering good root oxygen access and moisture retention.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are the cubes sterile and reusable?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The cubes are inorganic and sterile; they are typically used for a single crop cycle to maintain cleanliness.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"VIVOSUN","offers":[{"title":"Default Title","offer_id":45827247636666,"sku":"B0CQ7W5RZZ","price":38.87,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/3536\/8890\/files\/vivosun-1inch-rockwool-cubes-pack-shot.jpg?v=1777984602","url":"https:\/\/gardencanada.ca\/products\/vivosun-1-inch-rockwool-cubes-100-plugs-for-hydroponics-propagation-seed-starting","provider":"Garden Canada","version":"1.0","type":"link"}
