This high-yield \"Mega\" block is designed for maximum efficiency, expanding to a substantial 65L of high-quality potting substrate when rehydrated. Naturally derived from renewable coconut husks, it offers an eco-friendly and sustainable alternative to traditional peat-based mixes. The unique honeycomb structure of the coir fibers allows it to absorb and retain up to eight times its weight in water while maintaining excellent air porosity, ensuring that roots remain hydrated without becoming waterlogged. Naturally sterile and pH neutral, Brunnings Coir Potting Mix provides a clean and stable foundation that helps protect vulnerable plants from soil-borne pathogens. Whether you are filling large outdoor planters, creating custom potting blends, or improving garden soil texture, this versatile coir substrate delivers the consistent moisture and high-oxygen environment required for vigorous and healthy plant growth.\u003c\/p\u003e\n  \u003chr\u003e\n  \u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Maximizing water retention in large containers, providing a sterile foundation for high-volume seed raising, and improving soil structure in garden beds.\u003c\/p\u003e\n\n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n      \u003cstrong\u003eSignificant 65L Expansion:\u003c\/strong\u003e A highly compressed, space-saving block that expands to approximately 65L, providing exceptional value and coverage for professional landscaping and large home projects.\n    \u003c\/li\u003e\n    \u003cli\u003e\n      \u003cstrong\u003eExceptional Water Management:\u003c\/strong\u003e The natural coir fibers act as a biological sponge, retaining significant reservoirs of water and reducing the frequency of irrigation required during hot periods.\n    \u003c\/li\u003e\n    \u003cli\u003e\n      \u003cstrong\u003eEnhanced Root Aeration:\u003c\/strong\u003e High-porosity structure ensures that essential oxygen reaches the root zone, promoting faster establishment and preventing the risk of root rot.\n    \u003c\/li\u003e\n    \u003cli\u003e\n      \u003cstrong\u003eSustainable \u0026amp; Renewable:\u003c\/strong\u003e Produced from 100% natural coconut husks, offering a high-performance, environmentally responsible alternative to peat-based products.\n    \u003c\/li\u003e\n    \u003cli\u003e\n      \u003cstrong\u003eSterile \u0026amp; Pathogen-Free:\u003c\/strong\u003e Provides a clean growing environment free from weeds, pests, and soil-borne diseases, making it safe for delicate seedlings and indoor specimens.\n    \u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eSpecifications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Brunnings\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e Coir Potting Mix\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e Expands to approximately 65L\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Compressed Coco-Coir Block\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCategories:\u003c\/strong\u003e Coir \/ General Potting Mixes\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eIdeal For (Uses)\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLarge Container Gardening:\u003c\/strong\u003e Filling expansive patio pots and troughs with a lightweight, moisture-retentive medium that supports long-term growth.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCustom Potting Blends:\u003c\/strong\u003e Mixing with perlite, vermiculite, or compost to create specialized high-performance substrates for tropical foliage and hanging baskets.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoil Conditioning:\u003c\/strong\u003e Incorporating into existing garden soil to improve the water-holding capacity of sandy soils or to enhance the aeration of heavy clay.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh-Volume Propagation:\u003c\/strong\u003e Providing a soft, hydrated, and sterile medium that encourages rapid root initiation for large batches of seeds and cuttings.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Multicrop","offers":[{"title":"Default Title","offer_id":48124648915044,"sku":"30580","price":24.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/30580.jpg?v=1774554575","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/brunnings-coir-potting-mix-65l-professional-high-yield-sustainable-substrate","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
