About This

  • Balanced Nutrient Solution: Use Humboldts Secret pH Up and Down to adjust the pH of your plant nutrients. A balanced pH solution will allow your plants to achieve maximum nutrient absorption resulting in increased plant production.
  • Optimal pH: Most plants enjoy a pH between 5.5 and 6.5. Use pH Up with potassium hydroxide to raise your nutrient solution, and pH Down with phosphoric acid to lower your nutrient solution. Humboldts Secret pH Up and pH Down are 100% dye free.
  • Increased Strength: Humboldts Secret pH Up and pH Down are up to 25% stronger than some leading competitors, meaning a little goes a long way. To use, simply test your nutrient solution with a digital pH meter or pH tester strips, then balance your nutrient solution by using a few drops at a time of either pH Up or pH Down.
  • All Growing Mediums: Use pH Up and pH Down for plants grown in all growing mediums including soil, water, hydroponic setups, coco, dwc, and more. pH Up and down are essential supplies for a thriving garden. Not intended for aquarium or spas.
  • For Growers: Humboldts Secret products are designed by Growers for Growers. Achieve reliable results from our high quality pH Up and pH Down made with the finest ingredients and proudly manufactured in our California based facility.
