The measurement we use to determine the acidity or alkaline quality of water (or in this case soil) is called pH. The pH level in soil plays an essential part in several manners of gardening. Various plants thrive best in different conditions. Nutrient deficiencies occur when the soil is outside of the pH range best suited for a specific plant. The pH measurement ranges between 1 (the most acidic) and 14 (the most alkaline) with a pH of 7 being neutral. The best soil for weed is slightly acidic, between 6.0 and 6.5. High quality soil is usually in this range because, at this level, all the nutrients needed by plants in order to thrive are water soluble. Nutrients don’t dissolve as well outside of this range.

Hazards of Unbalanced pH in Marijuana Cultivation

A balanced pH can be used to obtain optimum soil for marijuana cultivation.

A lower, more acidic pH than 6 will cause marijuana plants to have less access to phosphoric acid, calcium and magnesium. A higher, more alkaline pH than 7.5 will prevent the roots from being able to absorb iron, copper, zinc, manganese and boron ions. In this way, it’s very important to be able to test your soil, which you can do using pH testing papers or a pH meter. Once you know the pH level of your soil, you can use simple methods to adjust the levels to get the perfect range for your plant.

Sandy Loam Typically Provides the Best Soil for Weed

In general, sandier soils are more acidic and clay oils are more alkaline. Woodland soil, also referred to as loam, fall in the middle. It’s important to note that woodland soil is often made from the decay of dead leaves and other organic substances, so the top of the soil may be a little more acidic. Sandy loam soil tends to be the best soil for weed, as the sand creates good drainage while the loam provides nutrient rich soil. Clay soil is usually very high in nutrients but the high alkaline nature makes it hard for plants to absorb the nutrients.

Augmenting Clay Soil for Optimal Results

Sandy loam is an ideal soil type for cannabis cultivation.

Clay soil can be fixed to be made usable very easily though. Chopped or ground leaves and pine needles can be added along with ground coffee and tea. Adding these to the soil and mixing them in well can provide your plant with a high nutrient soil. Just remember to do the adjustments before adding your plant to the soil and always test to make sure your soil is the right pH before planting. Hydroponic plants will usually thrive between a 5.5 and 6.5 pH range.

The pH balance of a plant will fluctuate as the plant grows and consumes nutrients. The best soil for weed will aim for a pH of 6, so the fluctuation range stays between 5.5 and 6.5. When the soil becomes too alkalized, the leaves of the plant will turn yellow. When it is too acidic, the plant will wilt and you will see burn spots on the leaves. Various foods and fertilizers can help to maintain an optimal pH level. A quick and easy way to make adjustments is by adding a little soil sulphur if it’s too alkaline and a little lime if it’s too acidic. Use pH testing papers to check on the water you are using to feed plants as well, so that you can ensure that it supports the best pH level for your soil.
