  • Packaging Update: You may receive previous or updated packaging during our transition. Same formula, same performance. Balanced Nutrient Solution - Adjust your feeding program using pH Down for plants to maintain the correct nutrient environment at every stage of growth. Balanced pH levels support stronger roots, efficient nutrient absorption, and steady development, helping your plants stay productive over time.
  • Optimal pH Control: Most plants respond best between 5.5 and 6.5 pH. Use pH Up for plants to raise levels and pH Down to lower them, ensuring nutrient availability remains stable. Our liquid formulas are dye-free and easy to apply, making them a consistent tool for growers in soil and hydroponic systems.
  • Potent and Efficient: With a formula up to 25% stronger than some alternatives, only small amounts are needed for effective adjustment. Apply pH Down hydroponic precisely with a digital pH meter or test strips, making it simple to fine-tune your nutrient solution for balanced growth in different environments.
  • Adaptable for All Growing Mediums: This solution is suitable for soil gardens, coco coir, DWC, and hydroponic systems. The pH Up and Down kit for soil allows growers to maintain consistent pH control across different methods of cultivation. It is intended for plants only and not for use in aquariums, spas, or pools.
  • 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.
