What is pH?
pH is the negative log used to know and determine the acidity/alkalinity of aqueous solutions by calculating the H+ (Hydrogen positive ion) activity in the solution. This scale has been developed from standard solutions with stabilised and known pH by international agreement.
Definition and measurement of pH
pH = - Log 10 (ªH+) = Log 10 (1/ªH+)
The pH range or scale is divided into 14 values; pH 7 is considered to be neutral, a pH value of less than 7 is called acidic, and pH values greater than 7 are considered basic or alkaline.
Influence of pH values on marijuana crops
As also happens in humans, plants have pH fluctuations in their metabolism, which mainly depend on the pH range and stability. Thus, cannabis plants have a better or worse development and overall health state depending on the pH, being more or less sensitive to pests and diseases.
