For grow rooms, several tents or commercial set-ups, the 5 L can of \u003cstrong\u003ePlagron pH- (59%)\u003c\/strong\u003e holds ten times the 500 ml bottle and cuts the cost per litre.\u003c\/p\u003e\n\u003ch3\u003eWhy growers use it\u003c\/h3\u003e\n\u003cp\u003eIt is a strong, concentrated \u003cstrong\u003epH down\u003c\/strong\u003e (59%, listed as NPK fertiliser 0-43-0) that brings nutrient water into the 5.5–6.5 range, where plants absorb nutrients in the right proportions in both veg and bloom. It works with all irrigation systems, from hand watering to automated drip.\u003c\/p\u003e\n\u003ch3\u003eHandling a 5 L can\u003c\/h3\u003e\n\u003cp\u003ePouring straight from a 5 L can into a reservoir is how overshoots happen. Decant a working amount into a small bottle with a dropper or dosing cap, and keep the can sealed. In automated systems, a pH controller with a dosing pump can draw from the can directly. Always mix your nutrients first, then add pH- in small steps, stir and measure until you reach 5.5–6.5. The amount depends entirely on your water and nutrients, so measure every batch.\u003c\/p\u003e\n\u003ch3\u003eSafety and storage\u003c\/h3\u003e\n\u003cp\u003eThis is a concentrated acid: wear gloves and eye protection when decanting, and store the can upright, closed and out of reach of children. Do not use pH- to fix a pH Plus overdose; that alters your feed's NPK. Mix a fresh tank instead.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 5 L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConcentration:\u003c\/strong\u003e 59%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e NPK fertiliser 0-43-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Plagron","offers":[{"title":"Default Title","offer_id":58748414493016,"sku":"C8PLA935916","price":65.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/9584\/8792\/files\/5f979bef3fb0aab9c32cc8577138146f.jpg?v=1791823875","url":"https:\/\/growdealz.com\/products\/plagron-ph-59-5l","provider":"Growdealz","version":"1.0","type":"link"}
