Ten Best Cannabis Soils (2021)

About a whopping 160 million people around the world use Cannabis and with its amazing medicinal and therapeutic effects, it’s no surprise tons of people are researching how to grow it. Most people have different opinions as to the best growing method, whether to grow indoors or outdoor or if it’s better to use soil or hydroponics but using soil is a great way to crop fat, flavoursome buds and this leads people to wonder what the best soil for cannabis is.

Picking the right soil when growing Cannabis is very important as it is one of the deciding factors of the health of your plants. Everything, including your growing conditions and species, will play a role.

It takes between 2-6 months to get your cannabis plant growing. During this period, they will need many nutrients to nourish and grow. This complexity is what makes the cannabis-specific soil market a successful one.

Specific soils for marijuana are made to foster the growth of healthy cannabis plants. Most pre-made potting mixes contain all necessary nutrients, vitamins, or microscopic organisms that allow the plants to flourish and thrive naturally.

It’s difficult to choose from a variety of cannabis-specific soils. Whether you’re looking for universal, organic, pre-fertilized, or everything-in-one substrates; there’s something for everyone.

This is the definitive guide to the best cannabis soils

You can call it dirt, soil, or growth medium. It is essential for every cannabis-growing operation. The best cannabis soil is the key to growing pot plants.

It can spell the difference of a success harvest or complete failure. Or, would you choose beautiful buds over a sickly plant? The right soil is key to this. You have many options.

Is there a best soil for marijuana? What pH level is best? Are you growing outside? What happens if you are growing indoors instead? These are just a few of the many questions that can be asked. My friend, don’t worry! Honest Marijuana experts are available to assist you!

Fast a decade ago, we were growing the highest quality cannabis anywhere in the world. Our cannabis is grown in organic 100-percent soil. We don’t use any chemicals or pesticides.

In those 20 years, we have learned much. We want to be able to help you. For that reason, we have the complete guide to the most suitable cannabis soils. This will ensure your head does not explode as you attempt to sort the vast amount of information. Let’s talk about the fundamentals of great cannabis soil.

Basics Of Good Cannabis Soil Cannabis, also known as weed, can flourish under different conditions. It doesn’t necessarily mean that you can just throw your seeds of sensimilla in your backyard and pray for the best. This isn’t Jack & The Beanstalk, bro.

Yes, your cannabis weed can grow in a wide range of soils, but to truly flourish to produce lots of trichomes , THC, and other cannabinoids it needs just the right balance of variables in the soil. You need to consider:

Proper drainage

Retention of water (sounds contradictory to the first variable but it’s actually not)

Proper nitrogen to phosphorus balance (this is accomplished in the composting process)

Best Soil For Indoor Cannabis

For indoor cannabis cultivation, organic super soil is best. In the second and third sections, we will show you how to create these essential items.

The organic super soil, in particular, gives you the right balance of carbon, nitrogen, phosphorus, and a whole host of other nutrients to ensure that your cannabis plant gets exactly what it needs during every stage of growth . The 420 fertilizer can be made by you and will result in tall cannabis plants that produce lots of marijuana and cannabinoids.

It is possible to buy soil instead of making your own. This is particularly good for those who don’t have a lot of space outside to set up a compost pile. We’ll talk about the best bagged soils in the next three sections.

Best Potting Soil For Cannabis If you must buy a bagged soil and your local garden store doesn’t have a lot of choices, anything with the words “organic potting soil” or “organic potting mix” will work. It’s not the ideal, but it will do in a pinch.

A mixture of organic soils and homemade super soil is the best choice.

One thing you want to look for when buying potting soil for cannabis is that it does NOT contain any slow-release chemical nutrients. These time-released chemicals could cause your cannabis plant to get the wrong nutrients. That could spell disaster for your cannabis crop.

These brands will help you find more plants in your garden.

Best Soil For Autoflowering Cannabis

It is the amount of sunlight a plant receives during the day that determines whether it flowers. These are called photoperiod plants. Indoor cannabis plants require between 12 and 15% of the day’s light. This usually happens in the later part of summer.

Of course, that variable can be controlled by growing your cannabis indoors (where the plant needs closer to 18 hours of fluorescent light).

But some cannabis plants are what’s known as autoflowering. Autoflowering means that the cannabis plant doesn’t need to be exposed to sunlight in order for it grow. The autoflowering stages of cannabis will occur when the plants reach certain developmental phases.

Autoflowering cannabis prefers a more light, airy soil with a relatively low level of nutrients. Many of the soils and mixtures discussed here are less than perfect. It doesn’t mean that “normal” soil can’t be used. You will get better results with lighter soil.

Try mixing your own autoflowering soil with the following recipe:

3 Parts Compost

3 part peat moss

2 parts perlite

1 part wet vermiculite

You can use the following sections to help you make the best cannabis soil.

Take into account the soil

Regardless of the medium you select, there are several variables you should consider when purchasing your marijuana growing soil:

Drainage: Purchase soil that has good drainage because plants will not do well if the roots get soggy. The majority of potting and cocoa coir soils will do it well. Even the most potent soil will become soggy over time if it is not watered enough.

The density of cannabis roots is important. They don’t want to have to grow too much. Soil that becomes too compacted will not be a good growing medium for your weed. Your finger must be able and easily to push your finger down into the soil. When purchasing soil, a quick test of soil density is to lift different types of soil bags (of equal volume) from different suppliers. They will feel denser if they are heavier than others.

pH: Cannabis prefers slightly acidic soil. The pH of your water may have a lower pH than you think, but most nutrients are likely to raise the pH. This is fine if you are planning to buy coco coir or potting soil. If you are mixing your own organic soil, it might be worthwhile to invest in a soil pH meter so you can “dial-in” your soil correctly. Different mediums have different pH levels. Coco coir’s pH is between 5.2 and 6.8. If a medium falls within this range it is considered neutral.

What is the Best Soil for Cannabis?

The plant’s environment and climate will dictate the best soil for cannabis cultivation. For example, soil with poor drainage may not be ideal for indoor plants. It could still be a good option for cannabis plants grown in dry or arid areas where water retention may be a greater concern.

In the next sections we will be discussing the best soils indoor and outdoor for cannabis plants. Another important factor to consider when choosing the best soils is whether you’re growing photoperiod or autoflowering plants. This genetic difference affects the development of flowers.

Photoperiod plants don’t produce flowers until their light cycle changes. Indoor cannabis growers mimic this effect by dimming the lights. Autoflowers have been “programmed” so that they will flower faster. Even though photoperiods take longer time to grow, the yields they achieve are much higher than autoflowers.

Autoflowers can grow marijuana year round, and they don’t depend on the seasons. Autoflowers like a well-drained soil, that doesn’t contain too many nutrients and drains easily. Do not fertilize your autoflowers with heavy fertilized soils. They may become deficient in nutrients.

Autoflowers Require What Type Of Soil?

How do I choose the best soil to grow marijuana indoors?

Sandy soils can be used for gardening and have great drainage. A great choice for indoor growers. Silty dirt is composed of fine-ground organic particle and minerals like quartz. Silty soils retain moisture well but are also able to drain water and can be handled easily when they get wet.

What is the Best Soil for Clones

Make sure to use high-nitrogen soil and pH 6. Soil should contain high nitrogen levels for clones, as opposed to soil with high phosphorus levels for flowering plants. You want to ensure the soil pH is around 6.
