What Should the pH of Your Marijuana Nutrients Be?

Hydroponics and pH

Before we look at what the optimal pH balance for marijuana nutrients, let’s first discuss hydroponics for a moment. Hydroponics is a method of growing plants; however, it is mostly used for marijuana, in nutrient rich water. Though it is possible to grow through the aids of various means (sand and gravel for example), these can negatively affect the pH balance of your nutrients, whereas the hydroponic system eliminates these issues.

Hydroponic growth is the best method of growing your marijuana as it allows you full control over the pH balance and adjusting your nutrients to suit the needs of the cannabis. Marijuana thrives at a pH of 5.5, though the range is at its highest anywhere between 5.2 and 5.8. To achieve this the nutrients enriching (or if you’re growing out of the soil and so on) the pH balance should be between 6.0 and 6.5. If the pH levels aren’t properly adjusted, the nutrients do not dissolve as well, making the plants nutritional values diminish.

To make sense of this, pH is the measure of acidity or alkalinity in water soluble substances. pH is the potential for Hydrogen in the substance. The numbers range from one to fourteen, seven being the neutral. Anything below seven is acidic, whereas anything over seven becomes alkaline.

Testing Your pH

Now that the hurdle of technicalities has been overcome, we can look at how to test the pH levels in your nutrients. A way of knowing that your marijuana may not be within the right pH ranges is to look at the leaves and the level of growth. If the leaves are small and dark green, and the plant grows very slowly you know that there’s an issue and testing the pH will resolve it. The best methods of testing your pH balance is either to use pH test papers or a pH meter. Collecting runoff water from the plan, you can either dip your Universal Indicator paper into the water (where the paper will change colour depending value of one to fourteen indicating the different acidity or alkalinity in a solution) or using the pH meter, where probes measure the voltage in different solutions giving you a reading on the pH balance.

The Best Methods to Adjust pH Levels

The best ways to lower pH

  • Phosphoric acid
  • Nitric acid
  • Sulphuric acid
  • Food grade citric acid

The best way to raise pH

  • Potassium hydroxide

Remember that when adjusting the pH balances to take extreme caution as you are working with highly dangerous chemicals which may have lethal results.

The Different Methods of Growing Your Cannabis

Now that we’ve discussed pH levels, how to raise it and how to lower it, Hydroponics and the lot, we can talk about the different methods of discreet growth and how to maintain the right pH in each of these environments. Depending on the various methods of growth, there will be different issues you may face.

Hydroponics

The much-discussed hydroponics method is a slightly trickier method of growing your marijuana as pH regulation is far more important than in soil growth. Since the soil does not act as a barrier between the nutrients entering the plant and the plant itself, the pH changes take effect far quicker than in soil growth. It is important to note this, as you will have to make sure that the plant has the perfect pH in order for the nutrients to be absorbed properly.

Soil

Unlike with hydroponics, growing weed in soil will bring far less pH related issues, especially with soils that feed the plant throughout its life, without the need of adding any other nutrients. Soil allows weed to grow in a natural environment, with various factors almost always adding to its growth rate (such as rain which generally has a pH between 5.5 and 6.0 which is near the optimal rate at which the value needs to be). Rain plays a big factor in soil growth, due to its acidity level, that frees up various nutrients which are unreachable to the cannabis plant beforehand. This allows the plant long term nutrients.

This is just a small look into the world of the fluctuations in pH levels in the various methods of marijuana growth. It is important to remember this if you’re looking to grow your own cannabis since there is such a fine line between where you can successfully grow and where the marijuana no longer accepts the nutrients presented.
