The mineral is expanded using heat to create porous granules that absorb water while still maintaining air spaces around developing roots.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in \u003cstrong\u003e15L and 30L bags\u003c\/strong\u003e, OzSprout vermiculite can be used on its own for selected germination applications or blended with coco fibre, seed-raising mix, potting mix or perlite depending on the crop and the balance of moisture retention and drainage required.\u003c\/p\u003e\n\n\u003ch2\u003eIdeal for Seed Raising \u0026amp; Propagation\u003c\/h2\u003e\n\n\u003cp\u003eVermiculite is particularly useful during germination because it helps maintain consistent moisture around seeds. A thin layer can be spread over newly sown seeds where appropriate, while vermiculite can also be incorporated into propagation and seed-raising mixes.\u003c\/p\u003e\n\n\u003cp\u003eIts high moisture-holding capacity makes it useful for growing media that dry too quickly. Vermiculite can also help retain positively charged plant nutrients within the root zone as part of an appropriate growing mix.\u003c\/p\u003e\n\n\u003ch2\u003eMix with Coco Fibre\u003c\/h2\u003e\n\n\u003cp\u003eFor wheatgrass, microgreens, seedlings and other tray-grown crops, vermiculite can be combined with \u003ca href=\"https:\/\/ozsprout.com.au\/products\/coco-fibre-growing-medium\"\u003eCoco Fibre Growing Medium\u003c\/a\u003e to create a lightweight, moisture-retentive growing mix.\u003c\/p\u003e\n\n\u003cp\u003eAs a practical OzSprout starting combination, mix \u003cstrong\u003e15L of vermiculite with one hydrated 2kg coco fibre block\u003c\/strong\u003e, or \u003cstrong\u003e30L with one hydrated 5kg block\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThese ratios are starting points rather than fixed requirements. Crops that prefer faster drainage may benefit from a lower proportion of vermiculite or the addition of a more freely draining component such as perlite.\u003c\/p\u003e\n\n\u003ch2\u003eSuitable for Microgreens \u0026amp; Wheatgrass\u003c\/h2\u003e\n\n\u003cp\u003eVermiculite can be incorporated into growing media for tray-grown crops where additional moisture retention is useful. It can be blended through coco fibre or another suitable medium, or used as a light seed covering for selected crops.\u003c\/p\u003e\n\n\u003cp\u003eFor tray growing, use the mixture in a \u003ca href=\"https:\/\/ozsprout.com.au\/products\/microgreen-wheatgrass-grow-tray\"\u003eMicrogreen \u0026amp; Wheatgrass Grow Tray\u003c\/a\u003e or another suitable propagation tray with appropriate drainage.\u003c\/p\u003e\n\n\u003ch2\u003eVermiculite vs Perlite\u003c\/h2\u003e\n\n\u003cp\u003eAlthough vermiculite and perlite are both lightweight horticultural minerals, they perform different roles. \u003cstrong\u003eVermiculite is primarily used for moisture retention\u003c\/strong\u003e, while perlite is generally chosen where additional drainage and aeration are required.\u003c\/p\u003e\n\n\u003cp\u003eMany growing mixes use both materials to balance moisture retention with airflow and drainage around the root zone.\u003c\/p\u003e\n\n\u003ch2\u003eUse in Pots \u0026amp; Containers\u003c\/h2\u003e\n\n\u003cp\u003eVermiculite can also be incorporated into potting and container-growing mixes where the existing medium dries too quickly or requires greater moisture retention.\u003c\/p\u003e\n\n\u003cp\u003eFor plants that prefer very free-draining conditions, use vermiculite conservatively and balance the mix with a suitable drainage component.\u003c\/p\u003e","brand":"Ozsprout","offers":[{"title":"15 Litres","offer_id":43692674646259,"sku":"VERMICULITE-15LITRES","price":11.9,"currency_code":"AUD","in_stock":false},{"title":"30 Litres","offer_id":43692674679027,"sku":"VERMICULITE-30LITRES","price":18.9,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0646\/1446\/5779\/files\/Vermiculite_6b8f3bf7-5df0-466f-a083-d1f37672014e.webp?v=1759265548","url":"https:\/\/ozsprout.com.au\/products\/vermiculite-growing-medium","provider":"OzSprout","version":"1.0","type":"link"}
