These companies do not alter the overall nutrient composition, but they add these nutrients in specific amounts to foster these crops' healthy growth. So, which is the best soil for cannabis growth? Read on to find out!

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.
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.
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.
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.
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 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.
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.
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.
