Buying Guide of Best Soil for Growing Cannabis

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.

The Type of Soil You Use Will Affect the Quality and Yield of Your Cannabis Plants

The need to use the right soil for your cannabis is almost as important as using the right nutrient solution. The main thing to keep in mind when looking at different types of soils for growing, is that it is not just about what you like and prefer, but also about how much experience you have with gardening and growing pot plants.

Many growers like to use organic soil because it is more natural and safe for your plants. Plus, it does not contain all of those nasty chemicals that you find in mineral-based soils such as Miracle Gro or Pro Mix.

But there is a catch: Because of the lack of synthetic chemical components, organic soil will require you to pay attention to other factors when you grow in them. In particular, your watering methods and overall attention to the overall nutrient needs of your plants will be crucial when growing with organic soil.

The Type of Soil You Use Will Affect the Quality and Yield of Your Cannabis Plants

If you are a beginner with no experience in growing cannabis, do not try to wing it by using an unknown miracle soil mixture that you found on some forum or bought from a local guy. Just use a good quality professional potting mix, such as Fox Farms Ocean Forest soil, and everything will be fine.

With that said, when you start understanding the nature of organic soils better, you can make your own mixtures with several different components. If you wish to do so, go ahead but always keep in mind what you are trying to achieve with your combination of soil components.

For example, if you are trying to make an organic soil specifically for growing cannabis, you can use items such as coco coir, Canadian sphagnum peat moss and vermiculite (in that order). There are other commercial mixes out there that may or may not work for your growing needs, but do not get tempted to make some weird concoction of items you found at the garden center because you will regret it. Just stick to quality products like Coco Coir or Fox Farms Ocean Forest.

To help you decide which type of soil mixes are good for growing cannabis, here is a brief summary of pros and cons of the most popular soils used by many organic cannabis growers:

Promix: A rather popular mix developed by Fox Farms which is widely available in Western countries. It is a quality soil but it is mostly intended for growing vegetables and not so much for growing marijuana, as this type of soil will require you to use more nutrients than if you were using a professional potting mix like Fox Farms Ocean Forest.

Fox Farms: Besides the Promix, this is another top quality soil that works well for growing cannabis. It comes in several different types and they all work good for your plants. In fact, you can even use just plain old FF Original to grow beautiful organic weed.

Coco Coir (also known as coco or coir pith): Coco is actually not used exclusively for growing pot plants, but it has become so popular among organic marijuana growers that I decided to include it here. It works great because it holds water well and yet it still allows oxygen inside the soil. Coco can be mixed with other types of soil ingredients to create a special mix for growing marijuana, but you have to be careful in how much of it you use because coco holds more water than other components.

Vermiculite: Vermiculite is actually the opposite of coco when it comes to holding water. It is not very popular by itself when used for growing weed, but it is often mixed with other components to allow them release water and nutrients at a steady pace which will benefit your plants.

Peat Moss: Another popular soil for marijuana growers that you can use by itself or mix with several different items such as vermiculite, coco coir or composted bark. It holds water well but it can dry out rapidly.

What is 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. Without proper soil drainage, it is easy to over-water your cannabis crops and influence their oxygen consumption rate, resulting in wilting. Without appropriate texture, it will be challenging for your cannabis plants to have strong root development. Alternatively, it can lead to the root becoming damaged or drying out faster without proper water retention.

What Is The Best Soil For Cannabis Plants?

Soil quite literally provides the foundation for a good weed harvest. That’s why finding the right type of soil is important for growing cannabis plants. For good growth and flowering, plants need soil that meets certain conditions. Texture is an important factor, as are drainage capacity and pH values. Finding out what soil types are the best match for your weed plants is definitely worth your while. In the end, that knowledge will reward you with strong and healthy cannabis that yields the biggest and most fragrant flower buds.

Finding The Best Soil For Cannabis Plants

So why would you bother with finding good soil? You just want to grow cannabis, right? Isn’t that just a matter of putting seeds in the ground and off you go? If only it were that simple. Without care for the right soil, you could get a meagre harvest, or your plants could even wither and die. With just a tiny bit of information on the best soil for cannabis plants, you’ll significantly increase your chances of healthy and bountiful weed plants.

Your plants take root in your soil in order to draw strength from the earth. Cannabis plants need nutrition, air, and water to grow. The wrong type of soil could cut off their supply of these essentials. In addition, it could increase the risk of contracting fungi or pests.

Because Top Seeds Deserve Top Soil

Which Soil Should You Choose For Your Weed Plants?

The soil in which you plant your seeds makes up the upper layer of the ground. In natural conditions, this is a mixture of organic remains, clay, sand, and tiny rock particles. If this is your first time growing cannabis, then you should invest in buying high quality soil. The soil ought to be sufficient to provide your plants with nutrients all throughout the growth cycle. That way, you won’t need to add any additional nutrition or growth boosters.

Look for the following factors when buying soil for cannabis plants:

pH Value

The acidity of your soil is indicated by its pH value. Soil has a pH value, just like a jar of pickles or battery acid. pH values can be high (alkaline) or low (acidic). For weed plants, pH values ranging between 6 and 6.8 are ideal. Slightly lower values will still allow the plants to grow. Most commercial potting soil has a pH value somewhere between 6 and 7, so these are well-suited for cannabis plants.

Keeping check of pH values is wise. If pH values deviate from your intended level, they may prevent your plants from absorbing water from the soil.

Water Retention

Your soil should be able to retain water. If the soil doesn’t trap water, it will simply drain away too quickly and the soil will dry out. This will cause nutrient shortages in your plant.


The right soil texture helps your plants grow by allowing the roots to develop freely. Roots are vital in providing water and nutrients to your plants. Good soil texture ensures enough air and nutrients for the roots. It also regulates the balance between drainage and water retention. Texture simply means the firmness or looseness of your soil. Soil that is too firm will be too hard and form lumps that prevent the roots from penetrating the soil. Soil that is too loose will not retain enough water.

Cannabis loves soil that is light and crumbly. This type of soil promotes healthy root growth, while still getting your plants all the nutrients they need. There’s an easy way to test your soil for this. Just grab a handful of moist soil and squeeze it. When you open your hand, the soil shouldn’t stick, but just fall back to the floor as loose bits of soil.

Rich In Nutrients

The nutrients present in the soil power the growth of your plants. The potting soil you buy usually contains enough nutrients. It might be wise to add some extra nutrients once your weed plants start to flower, since your soil could be depleted at that point. You can increase nutrient levels by adding compost, humus, or worm manure, for example.


Your soil should be able to drain water as well as retaining it. Drainage means water slowly dropping down to deeper layers of soil. Without drainage, the soil gets too moist, drowning the roots of your plants. Overexposure of roots to water can cause them to die off. You also increase the risk of fungi and rot. Keep in mind that cannabis plants generally like their soil to dry up somewhat before they receive new water.

Choosing Your Soil Type

You have a number of options at your disposal when choosing the best soil for your cannabis plants. You can also mix several types for your perfect personal blend. Sandy soil will not retain enough water. Silty soil drains a bit too fast, while clay soil will retain too much water. The best soil is a blend of these three: loam. Loamy soil is a mixture of sand, silty soil, and clay, with some added organic compounds. Loam has the optimal balance between retaining water and drainage, while also being rich in nutrients. The only downside to loam is its relatively high price. Still, you are bound to get a return on that investment. It will pay off in the form of big, strong, and healthy plants.
