What is pH?: pH is a measure of acidity or alkalinity. A pH of 7.0 is considered neutral. A lower pH is considered acidic then a higher pH, which is considered alkaline.

Spectrum Formulas pH Down upholds optimal concentrated pH levels for soil grown and hydroponically grown plants. If the pH levels are too elevated or too low, your crops will be damaged or even killed since the crops did not consume the proper nutrients anticipated. Spectrum Formulas pH Down is the most concentrated pH available on the market today.
It is imperative to preserve the correct pH levels in your reservoir or water tank. Spectrum Formulas concentrated pH Down is an economical, cost-effective and convenient way to adjust pH levels by using food grade phosphoric acid. Our pH Down solution can be added by small increments to your reservoir for great results!

Directions for use

When adjusting, to achieve the desired pH level for your solution, for hydroponically grown, soil plants and sphagnum moss, add small amounts of pH Down to your nutrient solution a little at a time, then test the pH level of the solution. Repeat this process and re-test your solution until desired pH level is achieved. For superior results, check pH levels daily. Recommended pH for most plants is 5.5 to 6.5. This product lowers pH level.
Spectrum Formulas pH aqueous solutions are specially manufactured from pure concentrates that are food grade.
