For one or two tents, a litre of \u003cstrong\u003eAptus Substrate Buffer Liquid\u003c\/strong\u003e lets you correct that whenever it happens, without rationing.\u003c\/p\u003e\n\u003ch3\u003eWhy growers use it\u003c\/h3\u003e\n\u003cp\u003eIt is a liquid buffer made of \u003cstrong\u003emicronised calcium\u003c\/strong\u003e in suspension, free from chlorides, ballast salts and contaminants. Because it is liquid, it acts quickly: one flush is usually enough to bring a low substrate pH back up and improve the buffer capacity of the medium. At the same time it provides a steady calcium supply. You can use it at any point in the cycle, in soil, coco and other substrates.\u003c\/p\u003e\n\u003ch3\u003eHow far 1 L goes\u003c\/h3\u003e\n\u003cp\u003eAt 20 ml per 10 L of water (1:500), one bottle makes 500 L of buffer solution. With a 50 L tank per flush, that is ten corrections.\u003c\/p\u003e\n\u003ch3\u003eDosing\u003c\/h3\u003e\n\u003cp\u003eCheck substrate or drain pH first. With a low reading, dilute 20 ml per 10 L of water and apply it as a flush. Keep this water separate from other products and do not adjust its pH. If you prefer not to measure, Aptus advises giving it once, a month after planting. Measure your drain between applications so the pH stays in range and you do not overshoot.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e 1 L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosage:\u003c\/strong\u003e 20 ml per 10 L (1:500)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e liquid\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eShake well before use, as micronised calcium settles at the bottom.\u003c\/p\u003e","brand":"Aptus","offers":[{"title":"Default Title","offer_id":58748592030040,"sku":"C8APT900683","price":37.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/9584\/8792\/files\/24b454f296b4175109d6a72144fed7f9.jpg?v=1791823275","url":"https:\/\/growdealz.com\/products\/aptus-substrate-buffer-liquid-1-l","provider":"Growdealz","version":"1.0","type":"link"}
