Exotower pH Down is ideal for exotower or garden tower systems, where the recommended pH range is 5.5-6.0. Exotower pH Down can also be used for any hydroponic system that requires a stable pH level. pH is a measure of how acidic or basic a solution is, based on the concentration of hydrogen ions. A pH below 7 is acidic, a pH above 7 is basic, and a pH of 7 is neutral (like pure water).
Directions: Use 1 tablespoon per gallon to lower the hydroponic tower garden water pH by 1 point until the desired pH is reached.
A perfect pH for an exotower or any garden tower is 5.5-6.0.
pH is a logarithmic measure of the hydrogen ion concentration of an aqueous solution pH.
pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic. pH of 7 is considered neutral (e.g., pure water).
