In the cannabis industry, Alkaline refers to the soil, or any substance, with a pH over 7. The need to maintain the right pH for cannabis growing is one of the most important fundamental cultivation parameters. pH is a measure of acidity/alkalinity. It affects many aspects of cannabis cultivation. Get the pH wrong and your plants won’t be able to absorb the necessary nutrients even if they are present, a phenomenon known as a nutrient lockout. In the case of cannabis, pH is typically around 6-7 when grown in soil. In other words, a slightly acidic cannabis soil ph is preferred for optimized mineral/nutrient absorption by the cannabis roots.
