Soil pH refers to the measure of acidity or basicity of soil. When it comes to growing plants such as cannabis, having the right pH level is essential. Though most plants like a somewhat acidic environment, cannabis plants respond best to pH levels between 6-7. There is no perfect pH level to obtain, so don’t feel stressed if the levels fluctuate a bit over time. Simply focus on ensuring that pH levels stay within an optimal range. Though your cannabis can survive outside of this range, getting the pH just right can help to ensure your plants are of the best quality.
It’s also important to note that too little or too much acidity in your growing media can inhibit cannabis growth entirely by blocking nutrient absorption. For this reason, using meters for hydroponic growing is a good idea. By understanding the pH levels of your soil or growing media, you can make adjustments and protect your plants.
