High-quality marijuana soil should have:
This type of soil is among the best organic options for cannabis. Clays consist of fine crystalline particles created via chemical reactions amongst minerals or other natural resources. You can mold or shape clay soil, but it is hard to work with and drains poorly.
Whether you want to call it dirt or a growth medium, soil is a crucial component for growing marijuana. Choosing the best soil for your weed is arguably the most critical decision you’ll make when growing cannabis at home. Getting it right is likely the difference between a bountiful harvest and utter failure.
Loam soil is a combination of sand, silt, and clay, typically in a 40/40/20 ratio. It has at least 20% organic compounds and can vary from being easy to work with to incredibly complex. To identify a loam soil, squeeze it. It should form a loose ball that quickly threatens to break apart.
If you are a beginner grower, you must purchase your soil from a garden store. Did you know that the vast majority of expert growers also buy their soil? A handy tip when talking with a store employee is to ask about the right kind of soil for tomatoes. It is an excellent option if you feel uncomfortable disclosing your desire to grow weed!

You must have in mind the number of plants you want to grow before making an order. This aspect will help you have a clear notion of the amount of soil you will require. For example, if you are interested in increasing 1-6 plants, it will be pointless to order a soil bale. Alternatively, if you are considering growing several plants in a large pot or container, then you must call a bale of soil or multiple bags of soil.

Generally, anything labeled as an “organic potting mix” will work. This type of mix hasn’t been amended with chemical slow-release nutrients, which is one of the main things you want to avoid with soil for cannabis. I know it sounds like heresy, but even the Miracle-Gro version of “organic potting mix” will work okay, because unlike their original potting mix it doesn’t contain chemical nutrients (though it still has poor drainage and moisture retention – almost any other type of organic potting mix is better!).

Important Cannabis Soil Considerations
Good Cannabis Soil
Rich and light composted soil. Since this soil doesn’t have a lot of perlite, it’s a good choice for a grower who doesn’t want to add a lot of extra nutrients or supplements in the water.
Some growers choose an amended and composted “hot” soil that slowly releases nutrients over time. With this type of soil, you typically just add water or natural supplements like worm tea from seed to harvest. Other growers prefer a lighter potting mix so they have more control, and give nutrients in the water once the plant roots have used up the nutrients in the soil. But which brands can you trust?
