{"product_id":"magnesium-carbonate","title":"Magnesium Carbonate","description":"\u003cp\u003eMagnesium Carbonate (Magnesite) is a slow-release, non-sulphate source of magnesium that doubles as a soil pH buffer — raising pH in much the same way as lime or oyster shell powder, but supplying magnesium instead of calcium. If you've used dolomite, you've used something similar — dolomite is calcium magnesium carbonate, while this is purely magnesium and carbon without calcium tagging along. That distinction lets you fine-tune your calcium-to-magnesium ratios with real precision, rather than being forced to add both every time you adjust pH.\u003c\/p\u003e\n\u003cp\u003eMagnesium is critical to enzymatic processes throughout the plant's life cycle, and running short of it will affect overall performance drastically — particularly flower quality and yield. Because magnesium carbonate is insoluble and non-acidic, it fills a completely different role to ingredients like kieserite or soluble magnesium sulphate, providing a long-term background supply rather than a quick soluble hit.\u003c\/p\u003e","brand":"Soil Supply Co.","offers":[{"title":"500g","offer_id":48918021931248,"sku":"MAGCARB-500G","price":12.0,"currency_code":"AUD","in_stock":false},{"title":"1kg","offer_id":48918021964016,"sku":"MAGCARB-1KG","price":20.0,"currency_code":"AUD","in_stock":false},{"title":"2.5kg","offer_id":48918021996784,"sku":"MAGCARB-2.5KG","price":40.0,"currency_code":"AUD","in_stock":false},{"title":"5kg","offer_id":48918022029552,"sku":"MAGCARB-5KG","price":70.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/1262\/6416\/files\/magcarb.png?v=1782530257","url":"https:\/\/soilsupply.co\/products\/magnesium-carbonate","provider":"Soil Supply Co.","version":"1.0","type":"link"}
