When your pH is too low, you need pH Up. You must know that a solution is acidic when it has a pH in the range of 0 to 6.9 and alkaline when it has a pH in the range of 7.1 to 14. Pure water or deionized water is neutral at pH 7. The ideal pH for most hydroponic gardening applications is between 5.8 and 6.5, with few exceptions.


  • Start adding pH Up in small quantities to the nutrient solution, a little at a time and then test pH. Repeat this process until you reach desired pH levels
  • Monitor the pH levels regularly to keep your plants within desired ratios
  • Have Complete Hydroponics pH Down in case the pH of the solution goes above the desired levels
  • 100% money back guarantee
