Say goodbye to nutrient lockout and hello to heavier harvests. Our scientists engineered pH Up with Caustic potash and pH Down with Phosphoric Acid, so you can easily achieve the ideal pH levels for optimal nutrient absorption. We’ve developed these highly stable buffers to give you precise control over your pH, even after dilution or adjustments between reservoir changes.

• Recalibrate pH levels with maximum buffers
• Highly concentrated formulas for longer use
