These can be used to check and calibrate your pH meter, and should be done regularly to ensure accuracy from your pH meter.\u003c\/p\u003e\n\u003cp\u003eSimply pour out a small amount to calibrate, and discard the used solution afterwards to avoid any contamination.\u003c\/p\u003e\n\u003cp\u003epH buffer 7 will calibrate your meter to neutral. It is recommended to also use pH buffer 4 to calibrate your meter so you have a two point calibration, rather than just calibrating to one level. This just gives more reliability.\u003c\/p\u003e\n\u003cp\u003eIncorrect acidity\/alkali levels can damage your plants and stop them from feeding as they should be.\u003c\/p\u003e","brand":"GROWTH TECHNOLOGY","offers":[{"title":"Buffer 7 - 300ml","offer_id":53573386568053,"sku":"2674","price":4.0,"currency_code":"CHF","in_stock":true},{"title":"Buffer 7 - 1L","offer_id":53573386600821,"sku":"2675","price":10.0,"currency_code":"CHF","in_stock":true},{"title":"Buffer 4 - 300ml","offer_id":53573386633589,"sku":"2676","price":4.0,"currency_code":"CHF","in_stock":true},{"title":"Buffer 4 - 1L","offer_id":53573386666357,"sku":"2677","price":10.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0561\/9092\/7032\/files\/nutrient-mangement-growth-technology-ph-buffer-4-7-70793539486069.webp?v=1780149213","url":"https:\/\/www.thehydrobros.com\/en-ch\/products\/growth-technology-ph-buffer-4-buffer-7","provider":"The Hydro Bros","version":"1.0","type":"link"}
