The 10 Best Organic Potting Soils in 2021

Best Organic Potting Soil

Growing marijuana requires growers to pay attention to a lot of fronts. They need to get the right kind of tents, provide the right lighting, use the right pots, trim the plants from time to time, make sure that the humidity and ventilation are just right, provide water at the right time and provide the right mix of nutrients that helps the plants bloom well. However, one thing that growers often tend to not focus too much on is the potting soil that they use. Over the course of this article, we shall be taking a closer and detailed look at some of the best organic potting soils in 2021.

Before we deep-dive into our list, however, it is also essential for growers (and especially first-time growers) to understand why soil is important for the plants, as well as what actually constitutes ‘soil’. It is also important to know about the different parameters on which soil is judged on – something that we shall be discussing in detail in this article. Knowing that will help you decide whether the soil you are buying is the right fit for you.

Everything That You Need to Know About Choosing Soil for Growing Weed

Soil is essentially a collection of dirt that helps act as a ‘medium’ for plants to grow in. Soil is basically the entry point for water and nutrients to enter the plant, which helps them grow. Sometimes, for the purpose of growing weed, when we refer to ‘soil’, it can also be dirt mixed with a secondary medium such as coco coir or peat moss. All of these elements bring in certain benefits of their own. However, the primary thing that you need to keep in mind is that good soil needs to have two basic properties – it needs to be absorbent in the right amount and it also needs to be one which can drain out the excesses.

Soil, which we primarily see as ‘dirt’ is essentially composed of three things: clay, sand and organic elements. Clay is the retentive part while sand helps drain better – excess of either of the two can result in a soil that either retains too much water or drains too much water away. The perfect mixture of clay and sand is referred to as a ‘loamy’ soil, which is basically fine clumps of soil which does not get too compact neither does it become too loose that all the water flows outwards.

The organic component is equally important. Good soil usually houses a number of organic components including but not limited to bat guano, earthworm castings, bird droppings, alfalfa meals, cottonseed meals, bone and feather meals, cowdung, etc. These act as natural fertilizers and sources of various macronutrients that your plant needs in order to thrive better. An overwhelming majority of growers prefer using organic components in their soil rather than using synthetic components. While the basic NPK nutrients have to be provided, having a soil rich in these organic elements is the best for the overall growth and development of your marijuana plants.

You need to keep all these things in mind before you purchase the best soil that suits your needs. For making this choice even simpler, here’s a list of some of the best potting soils that you can buy off Amazon in 2021:

How to Choose the Best Soil For Growing Weed?

Choosing the right kind of a soil for your plants is quite simple when you do it from a store. All you need to do is to dig your hands in the soil and feel the clumps. Generally, getting a soil which is clumpy yet firm, but not hard, is what you should be aiming at. Such a soil helps you on two fronts – first off, it makes sure that it retains quite a bit of water in its clumps, but secondly, given that it is not one compact slab, there’s enough space for any excess water to reach the bottom and eventually drain out. Overwatering or underwatering your plant could be disastrous for the health of your plants. There needs to be quite a balance between the sand and clay content in the soil as well.

Besides this, the organic components that go into the soil also matter a lot. Growers prefer buying soil that is rich in as many organic components as possible. However, sometimes you might be looking only for a particular type of organic product which you could add to your existing soil to improve it. So all of these aspects need to be considered before you purchase your soil.

Frequently Asked Questions About Organic Potting Soil

Growers tend to ask us a number of different questions when it comes to choosing the right kind of organic potting soil for their plants. Here’s a list of such questions collated together at one place for your ease:

1. What kind of soil is the best for growing weed?

Loamy soil, which is neither too sandy nor too clayey is the best kind of soil for growing marijuana plants. Such a soil is perfect for retaining water and nutrients in it – while also ensuring that neither your plant gets waterlogged nor does it face a shortage of water caused due to excessive drainage. You should be looking for the perfect combination between sand and clay, as well as at the organic components that are present in your soil.

2. What organic elements need to be present in the soil?

Talking about organic elements, your soil needs to be rich in them – there need to be as many organic elements present as possible. However, most growers use this soil to mix it with their soil to compensate for whatever they are lacking in. These organic elements include things such as bird droppings, bone and feather meals, earthworm castings, and a number of different such organic elements that have assimilated into the soil over the years.

3. Do organic potting soils also need additional nutrients?

Yes, in almost all cases you will need to provide the NPK (Nitrogen, Phosphorus and Potassium) nutrients to the soil. These are the three basic elements that your plant needs the most of during different phases of its growth. While the organic components provide an additional boost to your plants, they are just there for that ‘boost’. The three main nutrients that are essential for the growth are the NPK nutrients mentioned above.

4. Where can I buy soil for growing weed?

The best organic potting soil that you can find for your marijuana plants in 2021 can be purchased either from Amazon, or by visiting an actual store. Amazon is one of the best places to get that given the nature of the ongoing pandemic, the impact of which is likely to linger around for quite some time. It provides a safe platform without you having to go out to buy the soil, and the return policies are favorable for growers who are disappointed with what they get.

5. Do outdoor growers also need to provide additional nutrients to their plants?

Yes, even outdoor growers need to provide additional nutrients to their plants as the NPK nutrients are critical in any condition. It doesn’t matter where you are growing your weed, providing these nutrients is essential for the overall well being of your plants.

Conclusion

We hope that by this point in the article you have gotten a fair idea about what kind of a soil you need when it comes to growing marijuana.
