Growing 101

Starting at the beginning

Soil is an essential component for producing cannabis, whether you call it dirt or a growth medium. When it comes to producing cannabis at home, selecting the right soil is possibly the most important decision you’ll make. Getting it properly could mean the difference between a bumper crop and a total disaster.

There are a lot of different soil brands to choose from, which is both good and bad. There are numerous solutions available to you. However, how can you choose the finest soil for growing cannabis when there are so many options? The key is to assess your circumstances, and our article will assist you in doing so.

What is the Best Cannabis Soil Mix?

The most obvious feature when picking and mixing soil is texture. The texture of the soil is often separated into three categories: silty, sandy, or clay. The texture determines the overall structure of the soil (cannabis soil).

Silty Soils

Because of their medium granular size, silty soils have a slightly finer texture. This results in better water retention while yet allowing your cannabis plants to grow steadily. Silt’s mineral and organic content make it a nutrient-rich, fruitful soil for your cannabis, but it’s still not as good as some other possibilities. While the advantages are numerous, they are accompanied by less efficient drainage.

Sandy Soils

Sandy soils have a coarse texture since they are made up of big granules. This coarseness facilitates water drainage and aeration while also being simple to deal with. The poor water retention of sandy soil, on the other hand, causes rapid drying and frequent watering. This is on top of the fact that sand has no beneficial nutrients for your cannabis plants. Sandy soil is not the greatest soil for cannabis cultivation.

Clay Soils

Clay granules are even smaller than those found in silty soil, measuring less than 0.002 millimeters. It also contains a lot of minerals and nutrients, making it a very fertile soil for your cannabis plants. Clay’s composition, on the other hand, is heavy and difficult to control, and its draining skills are poor.

While silty, sandy and clay soils each have their own set of advantages, combining all three yields the optimum soil combination for cannabis.

Loamy Soils

The ideal way to pot your cannabis is with a 40:40:20 mixture of sand, silt, and clay. This blend ensures that the final product has the best characteristics of each soil: sand drainage and air flow, silt water retention, and clay minerals and nutrients. Overall, this makes it an excellent weed-growing soil.

You won’t have to look far for loam if you’re seeking for it. The majority of potting soils in the garden area of any supermarket are classified as loam.

While clay can be tightly compressed and sand frequently fails to compress at all, loam can compress and keep its form for a little period before breaking down into its varied crumbles. There may be a range of amendments in those crumbles that provide a superb nutritional structure for your cannabis plants.

Improve the Soil Quality of Your cannabis/b>

It’s easy to become overwhelmed once you’ve figured out the structure of your soil. Although every option in front of you is loam soil, the diversity is great, and your senses are overwhelmed by an unknown array of gardening jargon: perlite, worm castings, bone meal, etc.

It’s a complicated procedure, so simply relax and enjoy the nutrients and bacteria. Various amendments have added a variety of soils, and these store-bought soils provide an excellent foundation for the growth of your weeds. Even yet, it’s up to you to fill in the gaps and make your soil the best cannabis soil it can be.

Worm Castings

While a worm farm can provide an unlimited supply of worm castings, the squeamish grower can still purchase bags of the stuff from nurseries or online. Worm castings distribute nitrogen into the soil on a regular basis, boosting soil health and plant growth. The chlorophyll molecule, which is responsible for making ‘food’ during the photosynthesis process, contains nitrogen as a key component.


Perlite is gradually becoming one of the most popular soil additions in gardening circles. Perlite is a volcanic gas that improves soil drainage and air circulation. Perlite is often pre-added to commercial soils, but if you’re working with natural soil, adding 10-15% perlite may provide the necessary results.


Vermiculite is extremely similar to perlite in terms of composition and application. It helps to achieve your desired level of water retention rather than enhancing water drainage. A good mix of perlite and vermiculite can help with moisture control and aeration, resulting in weed-friendly soil.

Coco Coir

Coco coir, or regenerated natural fibres from coconut husks, is a terrific soil addition that will boost your produce. It can improve water retention without making your (cannabis soil) heavy or tough to work with if you add it to your mix. If your soil base doesn’t already contain coco coir, you can add up to 30% to achieve the required benefits.
