The 1 L pack of \u003cstrong\u003ePlagron Supermix\u003c\/strong\u003e is made for exactly that small job. It is an organic powder fertiliser that you mix into the soil, with minerals, trace elements, worm castings and seabird guano for a balanced nutrient ratio and an active soil life.\u003c\/p\u003e\n\u003ch3\u003eHow much soil 1 L treats\u003c\/h3\u003e\n\u003cp\u003eFor potting soil, Plagron advises 25–50 L of Supermix per 1,000 L of soil. One litre therefore upgrades roughly 20 to 40 L of soil, which is two or three 11 L pots. Outdoors, the rate is 1 L per 10–20 m².\u003c\/p\u003e\n\u003ch3\u003eWhy growers use it\u003c\/h3\u003e\n\u003cp\u003eWith NPK 1-2-0, Supermix gives used soil a new lease of life and supports strong, vital plants. Worm castings and seabird guano feed the micro-organisms that make nutrients available. It is suitable for organic cultivation.\u003c\/p\u003e\n\u003ch3\u003eIn practice\u003c\/h3\u003e\n\u003cp\u003eBreak up the old soil, remove the root balls, then mix Supermix evenly through it before planting and water well. It is meant for peat-based substrates only, not for coco. Plagron's pre-fertilised Allmix, Royalmix and Batmix need no extra for the first grow; use Supermix to recharge them for the next one.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 1 L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK:\u003c\/strong\u003e 1-2-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e minerals, trace elements, worm castings, seabird guano\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedium:\u003c\/strong\u003e peat-based substrates\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Plagron","offers":[{"title":"Default Title","offer_id":58748390867288,"sku":"C8PLA935105","price":13.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/9584\/8792\/files\/d0a2b58753f71eb7bf64e853de993453.jpg?v=1791823968","url":"https:\/\/growdealz.com\/products\/plagron-supermix-1l","provider":"Growdealz","version":"1.0","type":"link"}
