General Hydroponics pH Control Kit

Dial in your plant nutrition with the all-in-one General Hydroponics pH Control Kit! Testing the pH of your nutrient solution has never been easier - or more important. This essential task matters for every grower because plants thrive in a very specific pH range: 5.5 - 6.5. Outside this window, certain nutrients become locked out, leading to deficiencies that can be hard to diagnose and correct. By testing and adjusting pH from the start, you prevent problems before they start and help your plants reach their full potential in yield and potency. With pH in the ideal range, your plants can uptake all the nutrients you provide. It only takes a few moments, but it can make or break your grow. After adjusting, re-test to confirm your nutrient solution is now in the correct range (5.5 - 6.5).

What causes pH to drift out of range?

Several factors can shift pH, including:

• Tap water, which often contains minerals and impurities.
• The varying rates at which plants consume different nutrients.

pH Color Chart

• Yellow to Yellowish-Green Indicates the ideal pH range for plant growth (5.5 - 6.5).
• Orange or Red Indicates pH is too low (below 5.5). Add pH UP (Base) to raise it.
• Blue-Green or Blue Indicates pH is too high (above 6.5). Add pH DOWN (Acid) to lower it.
