One kilo therefore buffers about 1,000 L of soil or 500 L of coco. That is twenty 50 L bags of soil, or roughly 45 pots of 11 L filled with coco. Plenty for a full tent or a series of runs.\u003c\/p\u003e\n\u003ch3\u003eWhy growers use it\u003c\/h3\u003e\n\u003cp\u003eNext to pH stability, the calcium becomes a steady Ca source for your plants during the grow. It is also a smart way to upgrade used coco so you can run it again. The formula contains no chlorides, ballast salts or contaminants.\u003c\/p\u003e\n\u003ch3\u003eIn practice\u003c\/h3\u003e\n\u003cp\u003eSpread the powder over your substrate in a tub or on a tarp and mix thoroughly before filling pots. A kitchen scale helps you stick to the recommended dose; more is not better here. Need to adjust pH later in the cycle? That is a job for its partner, Substrate Buffer Liquid.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e 1 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e micronised calcium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosage:\u003c\/strong\u003e soil 1 g\/L, coco 2 g\/L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e powder\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Aptus","offers":[{"title":"Default Title","offer_id":58748597174616,"sku":"C8APT900685","price":19.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/9584\/8792\/files\/c270cd353e4364d1ebc28edbef101786.jpg?v=1791823293","url":"https:\/\/growdealz.com\/products\/aptus-substrate-buffer-powder-1-kg","provider":"Growdealz","version":"1.0","type":"link"}
