Drip Hydro pH Up (5 Gallon) is a commercial-grade, highly concentrated pH adjuster designed to raise the pH of irrigation water and nutrient solutions effectively. Formulated with potassium hydroxide, it helps optimize nutrient availability by bringing your solution into the ideal pH range for healthy plant growth. Just 0.25 to 1 mL per adjustment provides precise control with minimal usage. The 5-gallon size is perfect for large-scale growing operations using hydroponics, coco, or soil-based systems. The potassium-based formula provides an NPK analysis of 0-0-45, supplying potassium without adding nitrogen or phosphorus.
