What is the ideal soil ph level for growing marijuana?

pH is the level of anion and cation uptake by a plant through its root. This ensures the proper nutrient uptake. Soil pH is one of the important factors that must be controlled with in an ideal range to give the best marijuana crop. The range of ideal pH for cannabis plant cultivation varies slightly due to the technique being used. For example, if you are using hydroponic cultivation for marijuana you must ensure that your nutrient solution has a pH in the range of 5.5 to 6.8. This is the ideal pH range for hydroponic planting. But if you are cultivating organic cannabis you must maintain a pH within the range of 6.5 to 7 for the best growth of weed crop. If pH is maintained within the ideal range, the pot plant will absorb all the necessary nutrients for its growth. If pH is outside this ideal range, your crop might suffer from deficiencies.

What is the ideal soil ph level for growing marijuana?


For hydroponic technique, it is essential for you to check pH of water at least once every week and measure pH after adding any chemical or nutrient to solution. For organic weed farming, pH must be checked once in one or two week's time. We must ensure the pH is in the optimal range as if the soil or solution becomes alkaline that is above pH 7.5, certain nutrients like iron, copper and manganese will not be absorbed by cannabis plant and if the pH becomes acidic that is below pH 6 the nutrients like magnesium and phosphoric acid will become less soluble. The pH can be checked through soil test kit. We combine sample of soil with a chemical solution. The result of mixing these two will give us a specific color that can be compared to a give chart that has color associated with a pH value. This is an easy and reliable procedure to judge pH of marijuana crop.


Why is soil ph important?

Soil pH is an extremely important factor to control for marijuana as it affects the nutrient availability to weed plant thereby affecting growth and quality of crop. If your soil is solution pH is not optimal for cannabis plant it will show plant disorders like yellow and shriveled leaves.


How can I determine the ph level of my soil used in growing?

There are various methods of checking pH of the solution or soil. The most popular pH testing methods for Pot is the use of soil testing kits and electronic pH meter as both are cheap, easily accessible and easy to use by any lay man. Another method that can be used is litmus test.
