Growing Cannabis In Soil Vs. Other Medium

Nowadays, with the advancement of technologies, growing cannabis plants are not dependent on the best soil or organic potting soil mixes.

Rather, cannabis plants can even be grown without soil with just a mixture of nutrients and water. In short, hydroponic grow systems are also common for cultivation.

But which works the best?

Is growing cannabis in the soil better or other mediums like hydroponics?

Let’s find it out:

Growing Weed In Other Medium

With the help of various grow kits, tools, and equipment, cannabis plants can even be grown in just a soil-less medium full of nutrient water.

Yes, I am talking about the hydroponic growing system.

In the case of hydroponics, the soil is not needed as we use nutrient water as a growing medium.

The plant growth occurs in a pot or water container with roots dipped.

Weed cultivation in hydroponics consists of multiple benefits. For example, the hydroponics grow system uses less water than the traditional soil.

Additionally, as the plants are always dipped into the nutrient water, the growth of the plants takes place faster.

For a detailed guide, you can read our hydroponics grow guide here.

Further, there are also drawbacks to the hydroponics grow system. First, it requires skill to do a successful harvest with this system.

In hydroponics, you need to take care of your garden more. Otherwise, it can completely ruin all of your time and hard-work investment.

Therefore, newbie cannabis growers need to go for the traditional soil method.

It is simple, easy, and requires little skill compartively hydroponics to grow a plant. Also, the plant growth failure risk is low.

Growing Cannabis In Soil

Cultivating cannabis plants in soil is the traditional method of cultivation.

It is simple.

You put your cannabis plants into the soil, water them and provide proper drainage along with sunlight, and it grows beautifully.

However, you must also consider some environmental factors for some rough climate regions.

But, for the best output, you need the best quality soil.

Whether you choose organic or super soil, you need soil that consists of all the nutrients that can help grow marijuana plants easily and rapidly.

So, before we can find which potting soil is the best and how you can find them for your grow project, let’s know the advantages and disadvantages of cultivation in soil.

Advantages Of Growing Cannabis In Soil

  • It is the traditional method and easier than hydroponics or other complex systems that require some cultivation skills.
  • Good cannabis soil consists of all the nutrients; therefore, you don’t have to be stressed over choosing the nutrients in the case of hydroponics.
  • Natural soil consists of mineral particles, air, organic matter, water, and biological organisms, which are best for a plant to thrive naturally.
  • It is less costly in terms of investment for the supplies.
  • It is a natural way.

Disadvantages Of Growing Cannabis In Soil

  • The main drawback is that in the soil mix, there are natural bugs that live. Therefore, your plant might have the risk of them.
  • Also, compared to hydroponics, growth in soil medium can be slow.
  • You must choose a good potting soil for cannabis plants to thrive easily and rapidly.

What Is The Best Soil For Cannabis?

Now, you know the pros and cons of potting soil for growing cannabis plants.

Therefore, it is time to look around for the best soil for cannabis plants.

Various types of soil mixes and types exist, but you need to find the right and best one for your plants.

Unless you are not buying a specific potting soil, you need to check for some specific requirements that must be in the best soil for cannabis.

So, let’s check out those requirements you need to find an ideal soil for weeds.

Features Of The Best Soil For Cannabis

  • Nutrients

It is the most important factor.

Cannabis soils must-have nutrients so that they can help cannabis plants to grow.

Initially, the cannabis soil will have sufficient nutrients if you have a quality soil mix.

However, within 3-4 weeks, as your plant starts to flower, fewer nutrients will be left in the soil to help the plant thrive further.

It is where you should start manually putting nutrients into your soil mix.

The most common organic nutrients are bat guano, bone meal, earthworm castings, blood meal, coco fiber, sandy, loamy soil mix, etc.

These can help you generate plenty of plant nutrients in the existing soil through composting and quickly improve soil quality.

  • Drainage Capability

Good soil has drainage capability. You should be able to pour water into it and have it drain out within a few seconds.

That means that when you water your plants, the water should not stay on the top. Instead, it should drain completely. Otherwise, poor drainage can make your plants sick or even die.

  • Water Retention Ability

Water retention is the soil’s ability to hold the water for the plant to fetch for survival.

The best soil mix must have water retention capacity, too, because to let the plant thrive, the soil must have water in it.

And there must be a good balance between water retention and drainage.

  • Dark Appearance

Good potting soil will have a dark and rich appearance that will not be muddy.

  • Texture

The texture of a quality potting soil should be light and loose to allow root development.

An optimal loose soil allows the root to fetch oxygen and water and easily grow rapidly. Also, it helps in nutrient uptake as well.

  • pH Value

Good weed soil has a pH value between 6 and 7. It is not considered good soil if it is more or less than that.

pH fluctuation can affect the yield negatively, which you should avoid.

So, in short, good soil will have the correct texture, water retention, drainage capability, and balanced pH level for plant growth in the best way.

What Makes A Soil ‘Not Good’ For Cultivation?

As of now, you know what makes soil ‘good.’ So, so you should also know what factors make soil quality poor or not fit for cannabis cultivation.

Sandy Soil

The soil with most sand as its composition is not good for growing cannabis plants.

The main drawback is that sandy soil loses water at a higher rate. That means it will not have good water retention.

And as cannabis plants require water for nutrient uptake, it is not suitable for cannabis crops as it lacks nutrients.

Clay Soil

Like sandy soil, clay soil can not be your potting soil for cannabis cultivation.

A clay soil mix holds too much water, leading to water logging and damaging your crop.

Therefore, clay soil does not fit for cultivation.

Not Having A Good pH Level.

Even if you have one of the best organic soils for your project, it can affect plant growth and health if it does not have a balanced pH level.

That can ultimately lead to less yield from your garden.

If your potting soil is more or less than the balanced limit, it will be either alkaline or acidic, which cannot suit for healthy growth of marijuana plants.


How to choose the best soil for cannabis?

In high-quality soil for cannabis, there will be better texture, dark appearance, water retention, and drainage balance like Fox Farm Ocean Forest soil.

What is the best soil for cannabis?

The best potting soil for cannabis is loam, as it is for various other plants. It checks all the required boxes for an ideal soil for cultivation, like a good texture, balanced pH level (5.8 to 6.3), and better water retention and drainage capacity.

Can you plant cannabis in any soil?

If you are a yield or result-oriented grower, you should ideally prefer soil that can get you the highest possible results.
You can either go for your soil like super soil or buy any premium organic soil like Fox Farm Ocean Forest organic soils.

How to make your super soil?

You can make your super soil using 8 bags of coco fiber and mycorrhizae-rich cannabis soil. Add 25 to 50 pounds of earthworm castings to it.

Then take:

3/4 cups of Epson salt
1/2 cup sweet lime
3 lbs. rock phosphate
5 lbs. bloom bat guano
5 lbs. blood meal
1/s cup azomite
5 lbs. steamed bone meal
2 tbsp. powdered humic acid

Add all these together and mix them well, and voila! You have prepared your soil or super soil.

Can I grow exotic cannabis strains using this soil?

Yes, you can grow exotic marijuana using this soil!

How do you grow cannabis seeds using the direct soil method?

When transplanting seeds to moist soil, use tweezers on the seed body or cotyledons. Do not plant the seed in the ground. Instead, dig a hole large enough for the entire root, keep it in place, and gently cover it with the earth. If the seed has genuine leaves, ensure they are visible above the earth. Gently give water.

Can cannabis grow in compost?

Straight compost may still be too rich in nutrients, so combine it with some peat moss, perlite, and vermiculite, which will aid aeration and water retention. The compost will include some healthy organic nutrients, but you may still need to add some fertilizer with the water if you notice any shortages or maximum development.

How many cannabis seeds can you put in a pot with soil?

They will develop into individual soil pots that you may use as a growth medium. Plant a seed or two in each container, keeping the pots wet. Once the seedlings have sprouted, move them to a container, raised bed, or garden space in their Jiffy Pot.

What is the best soil mixture to grow marijuana?

If you are growing cannabis, you will almost certainly be providing a nutritional basis of fertilizer to the soil regardless. In terms of nutrients, you just want high-grade, all-purpose soil.
The most delicate soil combination for producing marijuana plants is loam. Loam is a blend of clay, sand, and silt that combines the most remarkable aspects of these distinct soil types while reducing their worst characteristics.

How does cannabis rejuvenate the soil it is grown in?

Hemp improves soil health by shading out weeds, lowering the need for synthetic pesticides, and bringing diversity to crop rotations. Hemp is also a marketable product with thousands of seed, oil, and fiber applications. Cannabis, too, has the potential to thrive in nutrient-depleted soils. In addition, the robust root system of industrial hemp may break up compacted soil, giving aeration and porosity while also stabilizing the ground, which aids in erosion management.

Can I grow weed without nutrients?

Marijuana is a versatile plant that may be grown in various ways. However, all plants require nutrition. Hemp and cannabis are high feeders for a high-quality product. Cannabis, in particular, requires more nutrients and different nutrients during different growth cycles. Not to mention the need for light, evaluating the pH of the water, careful trimming, and so forth. Check out your local indoor horticulture store or a cannabis-growing explosion.

How many cannabis seeds can you put in a pot with soil?

They will develop into individual soil pots that you may use as a growth medium. Plant a seed or two in each container, keeping the pots wet. Once the seedlings have sprouted, move them to a container, raised bed, or garden space in their Jiffy Pot. After being wrapped in a moist towel for a few days, you also plant your seed. As a result, it takes less time to grow.

Final Words

Soil is a crucial part of any cultivation project.
