Because it is concentrated, a small volume moves a full reservoir, which makes fine adjustment straightforward once you learn how your water responds. The potassium base means the correction adds an element the plant already uses rather than something inert. It suits \u003cstrong\u003esoil, coco and hydroponic systems\u003c\/strong\u003e alike and belongs in any grow room where feed is mixed by hand.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccurate correction\u003c\/strong\u003e - Concentrated formula lets you creep up on your target rather than overshoot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePotassium hydroxide base\u003c\/strong\u003e - Adjusts pH using an element that plants already take up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEconomical in use\u003c\/strong\u003e - Small doses move large volumes, so a bottle lasts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks in any medium\u003c\/strong\u003e - Suitable for soil, coco and hydroponic reservoirs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtects uptake\u003c\/strong\u003e - Keeps the solution in the range where nutrients stay available.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eThe Cost of a Nutrient Solution That Drifts Acidic\u003c\/h3\u003e\u003cp\u003eNutrient availability is governed by pH, not by how much you put in the tank. Let a reservoir slide down past the usable band and iron, manganese and zinc become over-available while calcium and magnesium lock away. What you see is interveinal yellowing and slow growth on plants that are, on paper, fully fed. Correcting upwards restores the chemistry so the feed you paid for actually reaches the root.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMix and stir your full nutrient solution before touching the pH.\u003c\/li\u003e\n\u003cli\u003eAdd pH Up a few millilitres at a time, stirring between additions.\u003c\/li\u003e\n\u003cli\u003eAllow the solution to settle, then re-test with a calibrated meter.\u003c\/li\u003e\n\u003cli\u003eRepeat in small steps until you hit your target for the medium.\u003c\/li\u003e\n\u003cli\u003eWear gloves and eye protection, and store the bottle sealed and upright.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e0.95 litre\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003epH increasing solution\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eActive Base\u003c\/th\u003e\n\u003ctd\u003ePotassium hydroxide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFunction\u003c\/th\u003e\n\u003ctd\u003eRaises the pH of nutrient solutions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSuitable For\u003c\/th\u003e\n\u003ctd\u003eSoil, coco and hydroponic systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Emerald Harvest","offers":[{"title":"Default Title","offer_id":53446967034122,"sku":null,"price":16.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/emerald-harvest-ph-up-0-95-litre-1.jpg?v=1785337922","url":"https:\/\/hydrocropshop.co.uk\/products\/emerald-harvest-ph-up-0-95-litre","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
