The Importance of pH when Growing Marijuana
The Importance of pH Value for Cannabis Plants
The pH value of the soil is used to determine whether that patch of land contains acidic or alkaline soil. This can be displayed as a numerical scale that ranges from 0.0 to 14.0. 0 describes soil that is extremely acidic while 14 is indicative of soil that is very alkaline. 7 is a neutral level with the soil neither acidic nor alkaline.
Why pH Value is Important
The pH value of soil regulates a number of things. For instance, it is responsible for determining how much nitrogen is released by organic matter due to the soil bacteria. It also determines how much of the nutrients are leached out of the soil and at what levels certain elements become toxic. It can also define the structure of the soil. Therefore, getting the right pH values so that the ideal conditions are created is of the utmost importance.
The Ideal pH Value for Cannabis
The best soil pH for cannabis plants is 5.5 to 6.5. The optimal value will also depend on whether the plants are being grown naturally or hydroponically. For instance the ideal hydroponic pH value tends to be around 6.0.
If the pH level becomes more acidic or more alkaline than this, then the plants will not thrive. With pH values lower than the ideal value, certain nutrients in the soil lose their solubility. As a result, the roots are unable to take in magnesium, calcium, and phosphoric acid.
On the other hand, if the pH value exceeds 7.5, the plant has a difficult time absorbing different nutrients. This includes iron, manganese, zinc, copper, and boron ions. Then, there is a matter of a particular pH level will be affected by the external temperatures. For instance, if the soil has a pH value of between 5 and 3 and the temperature exceeds 26 degrees Celsius, then there is a potential for the plant to develop fungal rot.
Identifying the pH Value of the Soil
It is important that you always know the pH value of your soil. This value can keep changing once the cannabis plants have been planted. The more nutrients that the plant takes in, the more likely it is that pH value of the soil will be changed.
Extreme changes will negatively affect the plants. They will not get the nutrients that they require and this can cause stunted growth, a poor bud, or could even lead to the death of the plants. Growers with hydroponic systems may check the pH value of the soil up to twice a day. This allows them to quickly recognize a deviation and make the necessary adjustments. With naturally grown plants, the growers can rely on different testing methods. At the same time, they can utilize the appearance of the plant in helping them to determine whether the pH value is ideal or not.
These are the reasons why cannabis seeds need to be planted in soils with specific pH values. It will determine how well the plants will grow and just how good the bud will be as well.
