Because soil has water, it obviously has a pH level. And because cannabis likes a slightly acidic soil, we’ll talk about why the perfect pH number is 6. If the soil has this number, it will allow the cannabis plant to flourish. If it goes a bit lower than 5.8 or higher than 6.3, the plant can still sustain itself but don’t expect it to produce excellent yields.

You can also use pots if you wish. You can place three- to five- gallon buckets or pots outside and fill them with organic soil (this will be described later). Make sure you check the amount of sunlight, temperature, rainfall, humidity, and pests.

The Ideal Soil for Indoor-Grown Cannabis Plant

Auto-flowering cannabis plants prefer lighter and airier soil with low nutrients. That means the types of soil we mentioned above aren’t ideal for them. But it doesn’t necessarily mean that you can’t utilize regular or ordinary soil. We’re saying that the results will be better if you use a lighter soil.

If you are a beginner when it comes to choosing the right potting soil for growing cannabis, this is the factor that you should focus on the most. For the potting soils that we’ve looked at above, you’ll find that these are mostly “plug-and-play” soils.

However, ensuring that the soil composition is suitable for your cannabis is an important factor. You can easily control the amount of water and oxygen. However, getting the basic cannabis soil recipe is something you need to invest in.

Factors to Consider When Getting the Best Soil for Cannabis

The beneficial microbes like bacteria and fungi (mycorrhizal) play an important role in the growth of your cannabis roots and plant in general. These creatures break down the nutrients making it easy for your marijuana to absorb them.

Usually an organic potting mix does not have enough nutrients to last your plants for more than a few weeks, so it’s a good idea to always supplement with cannabis-friendly nutrients, especially in the flowering stage when your plant is making buds and needs lots of extra Phosphorus and Potassium.

In order for a cannabis plant to grow and thrive, it needs a good mix of both water and oxygen at the roots at all times! Too much water and the plant roots can’t get enough oxygen (lack of oxygen at the roots is why plants get droopy from overwatering) but on the flip side if there’s not enough water retention the roots can be injured from drying out too quickly!

Now here are a few examples of good and bad cannabis soil so you can see the texture you’re looking for!

The following video shows the soil texture you want (this is Coco Loco, an excellent soil for growing cannabis)

However, when growing with Super Soil, it’s a good idea to avoid watering too much at a time, as extra runoff waterwill drain away some of the nutrinets. Try to give just enough water to saturate the soil with very little extra coming out the bottom. Since you won’t be adding more nutrients through the grow, you want to conserve what’s in the soil!

Although that list looks vague and complicated at the same time, the requirements you want to meet are actually pretty simple; let me break it down!

The composting process creates a “living” soil that is full of microorganisms in the rhizosphere (area around the roots). Properly composted soil has nutrient sources that slowly break down over the course of your plant’s lifecycle. It very closely mimics what happens in nature.
