What Does PH Stand For? Why Is It So important for cannabis
Ph stands for “potential hydrogen” as in how much hydrogen is in each of the substances being tested. The pH scale is a logarithmic scale that usually runs from 1 to 14. Each whole pH value below 7 (the pH of pure water) is ten times more acidic than the higher value and each whole pH value above 7 is ten times less acidic than the one below it. For example, a pH of 3 is ten times more acidic than a pH of 4 and 100 times (10 times 10) more acidic than a pH value of 5. So, a strong acid may have a pH of 1-2, while a strong base may have a pH of 13-14. A pH near 7 is considered to be neutral.
You may ask what does this have to do with cannabis. Well with cannabis, we actually use the pH scale for measurement on acidity in the plants water and feed. The cannabis plant prefers a pH environment of 5.5 to 6.5. When the pH environment rises in alkalinity above 7.5, the roots are not able to consume the available iron, copper, zinc, manganese, and boron ions in their vicinity, and when the pH lowers into acidity to less than 6 the roots are not able to access phosphoric acid, calcium, and magnesium because they lose their solubility. If the pH drops to between 5 to 3 with temperatures above 26 degrees Celsius fungal diseases become a threat to the plant.
