{"product_id":"essentials-lab-ph-1l","title":"Essentials LAB pH+ 1L","description":"\u003cp\u003eEssentials LAB pH+ is a concentrated alkaline solution (50% potassium hydroxide) which can be used in small, controlled doses to raise the pH (decrease acidity) of nutrient solutions. Mix thoroughly and measure with a calibrated pH meter to attain the desired pH reading. Ideal for adjusting large volumes of nutrient solution.    \u003cbr\u003eKey selling points:  \u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHighly concentrated \u003c\/li\u003e\n\u003cli\u003eCan adjust the pH of large volumes of nutrient solution \u003c\/li\u003e\n\u003c\/ul\u003e \u003cbr\u003eTechnical Specifications:   \u003cbr\u003e\u003cul\u003e\n\u003cli\u003e50% potassium hydroxide \u003c\/li\u003e\n\u003cli\u003ePH: \u0026gt;11.5 \u003c\/li\u003e\n\u003cli\u003eVolume: 1L \u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003eFAQs:  \u003cbr\u003eQ: How should I use Essentials LAB pH- to adjust the pH level of my nutrient solution? \u003cbr\u003eA: First, carefully check the pH of your nutrient solution. If the pH reading is too low, then the solution is too acidic. Add a small, measured amount of Essentials LAB pH+ to your nutrient reservoir and mix thoroughly. Check the pH level again and note how much it has changed. You now know how much a certain dosage of Essentials LAB pH+ has raised the pH in your reservoir, and from this you can judge how much more, if any, you need to add to achieve the desired pH level. \u003cbr\u003eQ: The pH level of my solution is already high. What should I do? \u003cbr\u003eA: If the pH is within the recommended range, you should do nothing. But if the pH is too high, then you should use Essentials LAB pH- to adjust it to a lower level, within the recommended range. \u003cbr\u003e \u003cbr\u003ePurchase this with…  \u003cbr\u003e09-410-022 - Essentials pH Meter - With Memory Function \u003cbr\u003e09-420-055 - Essentials LAB pH- 1l \u003cbr\u003e10-485-035 - 10ml Plastic Long Pipette - 1ml increments \u003cbr\u003e \u003cbr\u003e","brand":"ESSENTIALS","offers":[{"title":"Default Title","offer_id":53420897632599,"sku":"09-420-075","price":7.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/2558\/9335\/files\/09-420-075.png?v=1777303376","url":"https:\/\/hydrohub.org.uk\/products\/essentials-lab-ph-1l","provider":"Hydro Hub","version":"1.0","type":"link"}
