pH

What is pH?

Definition: pH stands for potential Hydrogen. It is a scale of measurement used to describe how acidic or basic a substance is.

Lower numbers are more acidic and higher numbers are more basic.

This scale gives you an idea of where some common things fall on the pH scale.
Most plants like a neutral pH somewhere between 6-8.
