The Importance of Regulating pH When Growing Marijuana Plants

By nevash April 11, 2013 5339 Views Leave a comment Go to comments

There are many factors that contribute to healthy growth of marijuana plants, and one of them is proper soil pH. Generally, marijuana grown in soil requires a pH level that ranges between 6.5 and 7.0, while hydroponically grown cannabis crops often thrive in a pH solution of between 5.5 and 6.5. When these levels are not maintained, this creates room for plant related disorders to manifest. Most novice growers are often consumed with the importance of ensuring proper nutrition for marijuana plants without actually realizing that maintaining soil pH is one of the key components that contributes to the growth of healthy flowering plants that have potent trichomes. This is due to the fact that the pH of your marijuana plants plays a vital role in preventing nutrient related problems.  In fact, most marijuana nutrient deficiencies are not necessarily due to poor nutrition but often stem from pH imbalance within the growth medium or water. As a result of this, most nutrient disorders in cannabis plants can actually be evaded by ensuring that soil pH is within suitable levels.

The process of ensuring that the pH of your marijuana plants is within the recommended range begins with testing the growth medium. This is a task that needs to be done constantly throughout the different growth stages of your plants. Early detection of pH imbalance ensures that the problem can be corrected before it runs out of hand and much more serious disorders attack your weed plantation.

When testing pH, you will basically be testing the pH of water regardless of the growth medium used. A pH kit is one of easiest tools to use for this simple task, and you can find one at your local marijuana grow shop.

If you are cultivating your plants in a hydroponics set up, simply take a sample of growth solution and test the pH. Alternatively, make sure to check the pH of water that goes into the soil and that which drains at the bottom of the growing container.  If you tend to receive different results with each test, chances are that your pH kit is defective. Though a bit more costly, digital pH testers often provide accurate pH readings and they are the most preferred by most experienced cannabis growers. It is important to note that most of the times water with a higher or low pH tends to be the root cause of the problem. In such cases, make sure to adjust the pH of water before adding anything to the growth medium.

However, an adjustment of pH will be required in case the growing medium lacks the required pH level that marijuana plants need. There are a variety of ways that can be applied to correct pH that is either too high or too low. Regardless of the method used, it is imperative to gradually adjust the pH level of the growth medium so as not to shock your marijuana plants. An important aspect to remember is that pH readings need not to be accurate but rather within the recommended levels.
