Dial In Your Plant Nutrition With The General Hydroponics pH Control Kit Testing the pH of your nutrient solution has never been easier. This is an essential task for growers, because plants need a very specific pH range: between 5.5-6.5. When you extend above or below this range, certain nutrients start to get locked out, and your plant will develop nutrient deficiencies. By the time this happens, it can be tricky to determine what the root cause was, but if you simply pH your nutrients from the start, you can avoid this mess altogether! With pH in the right range, your plants will be able to uptake all the nutrients you feed them, and meet their full potential in terms of yield and potency. It takes just a few moments, and can make or break General Hydroponics pH Test Kits make pH testing easy. Fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator (Use 3 drops per 5mL of solution), and observe the coloration of the liquid in the test vial. Many experienced growers prefer our pH Test Kit to expensive electronic meters because it is reliable and easy to use. What causes pH to fall out of the ideal range? pH issues can be brought to fruition by a number of different things. One of the most common is the tap water you use to mix your nutrients. It typically has all kinds of minerals and impurities that can affect pH. Another cause is the rate at which your plant consumes certain nutrients, finishing some faster than others and thus affecting pH. Whatever the cause, you can rest assured the General Hydroponics pH Control Kit will help you stay on top of it! How To Use The General Hydroponics pH Control Kit Testing your solution takes just a few moments. Start by filling the test tube half full with your mixed nutrient solution. Then, add 3-5 drops of the pH test indicator to the vial and shake it - this will alter the color of your solution. You can compare the color in your vial to the pH color chart to determine if pH is too low, too high, or just right. pH Color Chart Yellow to Yellowish-Green - Indicates the ideal pH range for plant growth (5.5-6.5). Orange or Red - Indicates the pH is too low (below 5.5), add pH UP (Base) to raise nutrient pH. Blue-Green or Blue - Indicates the pH is too high (above 6.5), add pH DOWN (Acid) to lower nutrient pH. Repeat to verify the nutrient pH is now within the correct range (5.5 - 6.5.) If you'd like, you can learn more about the relationship between nutrients & pH in our learning center.
