Nutrient solutions can run too acidic depending on your water source, base nutrients and additives, and most plants want a feed pH somewhere around 5.5 to 6.5 to take up nutrients properly.\u003c\/p\u003e\n\n\u003cp\u003eAs with any pH adjuster, it's added in small amounts to the mixed nutrient solution and checked with a meter or drops kit after each addition, rather than dosed by eye or guesswork.\u003c\/p\u003e\n\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003epH Up solutions across the nutrient brands are broadly similar in function, with strength and bottle size being the main differences.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCompared with General Hydroponics pH Up, which is also potassium-hydroxide based, the two work in essentially the same way and at similar dose rates.\u003c\/li\u003e\n\u003cli\u003eCompared with Canna pH+, another alkaline adjuster, the practical choice usually comes down to price and pack size rather than performance.\u003c\/li\u003e\n\u003cli\u003eCompared with using baking soda as an improvised fix, a purpose-made pH Up gives a predictable, repeatable strength every time, rather than variable results.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIt's not a fancy product, but a correctly labelled, consistent-strength pH Up is worth more than saving a couple of pounds on an unknown alternative when you're dosing a whole reservoir.\u003c\/p\u003e\n\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003eDose gradually and always test as you go.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDosing\u003c\/strong\u003e\u003cbr\u003eAdd a few drops at a time to your mixed nutrient solution, stirring and re-testing pH until you reach the target range of roughly 5.5-6.5.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHandling\u003c\/strong\u003e\u003cbr\u003eThis is a strong alkaline solution - wear gloves and eye protection, and rinse immediately with clean water if it contacts skin, eyes or clothing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStorage\u003c\/strong\u003e\u003cbr\u003eStore the bottle sealed and upright, out of reach of children and pets, away from direct heat or sunlight.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eActive ingredient: \u003cstrong\u003epotassium hydroxide, approx. 25%\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFunction: \u003cstrong\u003eraises nutrient solution pH\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eSizes available: \u003cstrong\u003e250ml, 1L and 5L bottles\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eBrand: \u003cstrong\u003eGrowth Technology\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCompatible systems: \u003cstrong\u003ehydroponics, coco coir, soil\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eTarget feed pH range: \u003cstrong\u003eapprox. 5.5-6.5 (varies by plant\/media)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAny grower running a hydro, coco or soil system who needs to manage feed pH\u003c\/li\u003e\n\u003cli\u003eGrowers whose water source or nutrient line tends to run acidic\u003c\/li\u003e\n\u003cli\u003eNew growers building their first pH testing and correction kit\u003c\/li\u003e\n\u003cli\u003eAnyone topping up an existing pH Up\/Down pairing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eOur take\u003c\/h3\u003e\n\u003cp\u003eYou won't need pH Up as often as pH Down in most UK tap water setups, but when you do need it, you need it to work properly and predictably - which this does.\u003c\/p\u003e\n\u003cp\u003eDoes exactly what it should, day in, day out - worth keeping a bottle in the cupboard alongside your pH Down and testing kit.\u003c\/p\u003e\n\n\u003c\/section\u003e","brand":"GROWTH TECHNOLOGY","offers":[{"title":"250ml","offer_id":42568295841962,"sku":null,"price":7.0,"currency_code":"GBP","in_stock":false},{"title":"1L","offer_id":42568295874730,"sku":null,"price":9.99,"currency_code":"GBP","in_stock":true},{"title":"250mls","offer_id":47916010340522,"sku":"811912","price":4.99,"currency_code":"GBP","in_stock":true},{"title":"1 Litre","offer_id":47916010373290,"sku":"811914","price":9.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0053\/5540\/5400\/files\/growth_technology_-_ph_up_group.jpg?v=1769186007","url":"https:\/\/growershouse.co.uk\/products\/growth-technology-ph-up","provider":"Growers House ","version":"1.0","type":"link"}
