Buying Guide of Best Soil for Growing Cannabis

Buying Guide of Best Soil

Purchasing good soil for cannabis crops can appear to be less critical. However, it is one of the most significant aspects that determines the overall yield and health of your cannabis plants. Usually, these plants take approximately 4-6 months, from planting to harvesting. To help you make the right decision when looking for the best soil for marijuana, here are the aspects you must always consider.

Number of Cannabis Plants

You must have in mind the number of plants you want to grow before making an order. This aspect will help you have a clear notion of the amount of soil you will require. For example, if you are interested in increasing 1-6 plants, it will be pointless to order a soil bale. Alternatively, if you are considering growing several plants in a large pot or container, then you must call a bale of soil or multiple bags of soil.

Supplement-based vs. Stand-alone

This is another essential aspect that gives you options to choose from. The first option is selecting the soil mixes for cannabis that incorporate all the vital nutrition. The second option is choosing a mild soil mix that you can amend quickly with extra supplements. If you consider a stand-alone soil option, it most likely will not be ideal for seedlings because of its strength. If you ponder the milder soil mix, then you will require buying extra nutrients.

Many individuals find it worth buying soil mixes containing some nutrients because they will have the freedom of amending the overall minerals or nutrient content. However, you must have prior experience to execute this method successfully. For the novice, amending the soil mix can do more outrage than good. That is why they must consider the stand-alone soil option because it is an an-all-in-one soil mix.

Inorganic vs. Organic

You must also consider if you are interested in organic or inorganic soil options. Best organic soil for cannabis possesses organic ingredients. These ingredients are arguably proved to be user and environmentally friendly. On the other hand, inorganic soil counterpart seems to be cheaper and contains additional chemicals.

Living Soil

Lastly, you must know if you require potting soil for cannabis with essential microbes or not. You might be wondering why this is critical; however, bacterial and fungi play a vital role in nutrient breakdown. Simply put, beneficial microbes foster root growth, enhances absorption of nutrients, and offer a protective ground against fungi and bacteria.

What is the Best Soil for Growing Cannabis?

the best soil for growing cannabis

Growing cannabis, either indoor or outdoor, is accessible. Fortunately, it can be much easier, worthwhile, and a fantastic experience if you know the right kind of soil for growing these plants. Usually, three key aspects give the soil an upper hand to be considered significant for growing cannabis. First, when making an order, you must order the soil to guarantee the healthy growth of cannabis plants.

You must not underestimate the three key aspects when looking for the best soil for growing cannabis: good drainage, decent texture, and water retention.

Alternatively, it can lead to the root becoming damaged or drying out faster without proper water retention.


All plants require the right kind of soil containing the proper nutrients, aeration, and drainage. With this buying guide, it is easy to find the best soil for cannabis and avoid trial and error methods, especially for individuals with no prior experience.
