What is pH?

pH stands for potential hydrogen and is a measure of a solutions alkalinity represented on a scale from 0-14. A pH measure of 7 is considered neutral. A solution is considered basic if it measures between 7 and 14, while a solution measuring 0 to 7 is considered acidic. The pH of a nutrient solution is very important in hydroponics because it plays a big role in which macro and micro nutrients a plant can uptake.
