Plagron Silic Rock is a \u003cstrong\u003esilicon fertiliser of organic origin\u003c\/strong\u003e with 1.0% readily absorbable SiO₂. It strengthens cell walls for sturdier stems and leaves and supports the uptake of phosphorus, calcium and micronutrients.\u003c\/p\u003e\n\u003ch3\u003eIn practice\u003c\/h3\u003e\n\u003cp\u003eThe silicon\/potassium ratio helps plants stay steady under stress, from early growth through to harvest. That's useful in bloom, when branches have to carry weight, and in warm grow rooms where plants work hard. It runs alongside your normal feed in soil and coco.\u003c\/p\u003e\n\u003ch3\u003eHalf a litre, 500 litres\u003c\/h3\u003e\n\u003cp\u003eAt a maximum of 1 ml per litre, this bottle covers \u003cstrong\u003e500 litres of nutrient water\u003c\/strong\u003e. With a 50 L reservoir, that's 50 ml per fill and ten full tanks.\u003c\/p\u003e\n\u003ch3\u003eMixing order in a reservoir\u003c\/h3\u003e\n\u003cp\u003eFill the tank with water, add Silic Rock first and let it dissolve completely, ideally with a circulation pump or a good stir. Only then add your base nutrients and other products. This order matters with silicon products, because adding them to a solution that already contains nutrients can make them react. Use it at every watering throughout the grow and shake the bottle before each use.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVolume: 500 ml\u003c\/li\u003e\n\u003cli\u003eNPK: 1.5-0-1.7\u003c\/li\u003e\n\u003cli\u003eSiO₂: 1.0%\u003c\/li\u003e\n\u003cli\u003eDosage: max. 1 ml per litre (1:1,000)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor soil and coco; not suitable for NFT, DWC or aeroponics.\u003c\/p\u003e","brand":"Plagron","offers":[{"title":"Default Title","offer_id":58748334145880,"sku":"C8PLA935957","price":9.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/9584\/8792\/files\/ca2b2f7cb743199a534ac94426dd5018.jpg?v=1791823950","url":"https:\/\/growdealz.com\/products\/plagron-silic-rock-500ml","provider":"Growdealz","version":"1.0","type":"link"}
