The pH level plays an essential role in the uptake of nutrients by cannabis plants. For growers, itâs essential to understand what the pH level is and how it can be properly monitored and adjusted.
Letâs break down what pH is and why itâs important for cannabis. pH stands for âpotential of hydrogenâ and it is an indicator of the acidity or alkalinity of a substance. The pH level is measured on a scale from 0 to 14, with 0 being the most acidic and 14 being the most alkaline. The optimal pH level for cannabis plant growth ranges from 6 to 7; any deviation from this range can affect the plantâs growth and nutrient absorption.
When the pH level is too high, the plant can become over-saturated with nutrients and wonât be able to absorb them efficiently. On the other hand, when the pH is too low, the nutrients wonât be adequately absorbed and the plant wonât be able to take in enough of the necessary nutrients to properly grow and produce the best results.
While the optimal pH level for cannabis is 6 to 7, this range can vary depending on the type of soil the plant is growing in. For instance, in soil with a higher percentage of clay, the optimal pH level is around 6.5 to 7.5. In soil with a higher percentage of sand, on the other hand, the optimal pH level is around 5.5 to 6.5.
So, how can growers ensure that their cannabis plants have the optimal pH level? First, itâs important to test the pH levels regularly, to make sure they donât exceed the optimal range. Various types of testing kits are available, depending on the preferences of the grower. For instance, there are pH testing strips, drops, and meters.
Once youâve established the current pH level, you can adjust it accordingly. To raise the pH level, you can add dolomite lime, or to lower the pH level, you can add sulfur. Itâs important to adjust the pH level slowly – adding too much of either will shock the cannabis plants and can even cause them to die.
The pH level is critical for cannabis plantsâ absorption of nutrients, which in turn affects its overall health and growth. By monitoring and adjusting the pH level accordingly, growers can ensure their cannabis plants are able to absorb their nutrients properly and reach their full growth potential.
