pH is the value used to determine if a material is acidic, neutral or alkaline. It is measured on a scale from 0 to 14 where 7 stands for ‘neutral’.
pH is important because it determines how well nutrients can be absorbed by a plant. The ideal pH levels for cannabis plants is between 5.5 and 6.5.
Growers often refer to pH levels when they talk about the “acidity of water”.
