How to Choose the Best Soil for Weed?

Cannabis Soil with small plant growing

The best soil for weed or the best soil for cannabis is the type of soil, which is nutrient-rich and good drainage. Before purchasing or creating soil to grow, you should know about the soil requirements to grow cannabis. And below are some factors you need to consider.

Soil Texture

The texture is the most important feature of the soil, which can decide if your cannabis will grow or will die. Recently, clay, silt, rock particles, and sand are the most popular soil texture. The best soil for weed varies with different locations and climates.

  • Sandy soil is good drainage, has high oxygen levels, and can keep soil airy. But it has poor water retention, and you need to water your plant frequently.
  • Silty soil is rich in nutrients and minerals and good at retaining water. But it is terrible at drainage.
  • Clay soil is rich in nutrients and good at retaining water. However, it is tough to work with this type of sand because it is heavy and compact.

However, in my experience, the best texture is 20% sand, 40% silt, and 40% clay. People call this texture is loamy soil, and it is almost the best for growing every plant. The loamy soil has excellent water drainage and retention, rich in nutrients, and has high oxygen levels. But it is a little bit pricey.

If you miss any ingredient in the soil texture, you can add organic matter to the spoil. You need to understand the features of soil texture to have the right plan for taking care of cannabis.

Drainage Ability

Firstly, I want to emphasize that the best soil for cannabis needs to have excellent drainage. Cannabis, weed, and marijuana cannot be waterlogged. If you grow it in a poor drainage type of soil, your plan will turn out subpar yields, get sick and die.

As a result, clay is never the first option when looking for the best soil for weed, even if it is rich in nutrients. Besides, when taking care or watering, please note that the water should not pool on top of the soil. Too much water can cause your plant to die.

PH value

For your more information, PH value is a chemical scale that shows you how acidic or alkaline something is. Many people often ignore this value when choosing the best soil for marijuana. And they will always end up with dead plants but still don’t know why.

Cannabis only grows well within a small PH range. So whenever buying soil, you should check the manufacturer’s data to find out how much PH value is in the soil. The best soil for weed has a PH value within 5.8 and 6.3. It could be best if the PH value is 6.0.

If the PH value is too low or too high, your plant will grow slowly, and you will have diminished yields. And when the PH value is off, your plant will stop growing and die.

Soil Composition

The ideal soil composition for growing weed needs to contains organic material, air, water, minerals, and living organisms. The minerals in the soil consist of carbon, calcium, nitrogen, Sulphur, manganese, potassium, and phosphorous. This composition is must-have for proper-growth crops.

The organic matter is fundamental in soil composition, too. It brings nutrients and adds to the nitrogen levels to strengthen the crops. Organic matter comes from decaying and dead animals and plants that can add Sulphur and nitrogen so that your plant will grow effectively.

Moreover, air, water, and microorganisms are important factors in soil composition, too. Your plants need oxygen, water vapor, nitrogen, and carbon dioxide to grow. The microorganisms provide the soil with energy, while water will create the ideal environment for them to survive. And all of them will lead to a productive harvest.


Ingredient of the soil is the most important factors that you should consider when buying the best soil for weed. And the best ingredient is organic ingredients, no doubt! After finding the soil with organic ingredients, you should next check carefully to see if the soil consists of all the right ingredients for weed.

Cannabis needs some organic ingredients like kelp, pumice, compost, perlite, and more. You can start growing plants in the original topsoil. Then you should uproot them after they sprout to move to the bigger patio. After that, you can use the potting soil for more drainage and nutrients.

Take the Test before Buying

Of course, no seller allows you to make a trial without payment. You need to check the soil label carefully to see if it was organic or not. You need to check if it has a suitable PH value with the right composition for your plant to grow.

It could be best you should use your hand to feel the texture of the soil. If you feel the soil is airy, light, and fluffy, then congrats! You found the best soil for weed.

You should also take a look at the soil’s color to decide whether the soil is good or bad. The rich-nutrients soil should be darker than the crumbly pale sandy soil. Pale soil means that the moisture is low and not good for growing cannabis.
