The 5 L can of \u003cstrong\u003eAptus Substrate Buffer Liquid\u003c\/strong\u003e is for growers who correct at that scale and want a lower price per litre.\u003c\/p\u003e\n\u003ch3\u003eWhat's inside\u003c\/h3\u003e\n\u003cp\u003eA liquid suspension of \u003cstrong\u003emicronised calcium\u003c\/strong\u003e, free of chlorides, ballast salts and contaminants. The calcium raises a pH that has fallen too low and stabilises it by improving the buffer capacity of the medium, and it also gives plants a steady supply of calcium. Being liquid, it works fast: usually one flush does the job. It suits all media and every stage of the cycle.\u003c\/p\u003e\n\u003ch3\u003eFive litres, in flushes\u003c\/h3\u003e\n\u003cp\u003eAt 20 ml per 10 L (1:500) the can makes 2,500 L of buffer solution. A 200 L flush tank takes 400 ml, so you get about twelve full flushes of that tank from one can.\u003c\/p\u003e\n\u003ch3\u003eWorking at scale\u003c\/h3\u003e\n\u003cp\u003eTest pH on a few representative pots first rather than assuming the whole room is the same. Mix the buffer with plain water only, never with other products, and do not pH-adjust this water. Without measuring, one application a month after planting is the Aptus guideline. Check your drain between applications.\u003c\/p\u003e\n\u003cp\u003eMicronised calcium settles, so shake or roll the can thoroughly before every pour, and store it frost-free.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e 5 L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e micronised calcium in liquid suspension\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosage:\u003c\/strong\u003e 20 ml per 10 L (1:500)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Aptus","offers":[{"title":"Default Title","offer_id":58748597141848,"sku":"C8APT900684","price":137.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/9584\/8792\/files\/5f80f877ac739467e8f1e523b6934fa3.jpg?v=1791823286","url":"https:\/\/growdealz.com\/products\/aptus-substrate-buffer-liquid-5-l","provider":"Growdealz","version":"1.0","type":"link"}
