How To Make The Best Soil Mix For Growing Cannabis

Not only can you now buy cannabis online in Canada, but you can also grow cannabis at home. Growing cannabis is restricted in certain provinces, but most adults can grow up to four cannabis plants at home provided that they keep them out of view and out of the reach of children.

One of the most important parts of growing cannabis is the soil you use. Many marijuana growers use nutrient-enriched soil known as supersoil to ensure that their plants grow as successfully as possible. It can also help ensure that you get the best yields of cannabis possible. Here’s a guide on how to make the best soil mix for growing cannabis.

Buy Your Base Soil

Before making your cannabis soil mix, you’ll need to buy your base soil. While various kinds of soil can work, there are certain things you’ll want to look for if you want the best base possible for your cannabis supersoil. Ideally, the soil should be slightly acidic with a pH of 6 to 6.5. It should also be well-aerated and permeable.

Usually, organic soils are the best choice for your cannabis soil mix. These are usually already enhanced with various ingredients to ensure that your plants grow well. They may even contain some of the components you need to make a good cannabis soil mix, such as peat moss, perlite, vermiculite, guano, and coco fiber.

You can usually find a good soil base at any local gardening store. You can also find soil mixes online, although you’ll need to wait for delivery. Although organic soil costs more than regular soil, it usually works the best. However, even if you find regular potting soil with some helpful components, it can still work well for your plants – especially as you’re going to enhance it.

You’ll also need a few other things to grow cannabis. Don’t forget to buy feminized cannabis seeds and the equipment you need such as plant containers and equipment for lighting, heating, and humidity control.

Enhance Your Base Soil

After buying a large bag of base soil, it’s time to enhance it. Enriching your base soil with certain nutrients and components can boost the success of your cannabis-growing project. It’s also easy to carry out – place your base soil in a large container and break it up into chunks, allowing for better aeration. This will make it easy to add new ingredients and mix them into the soil.

Some of the best components to add to your soil include worm castings, perlite, vermiculite, bone meal, blood meal, coffee grounds, tea leaves, eggshells, fruit peels, compost, coco coir, sand, Epsom salts, compost, lime, and dolomite. Some of these ingredients will need to be broken down for them to mix properly into the soil.

If you’ve bought organic soil, it might contain some of these ingredients already. Check the ingredients of your base soil and check what you already have. You can then add some of the other ingredients to your soil. Some components need months to break down properly, so it’s best to prepare your soil months in advance.

How To Make The Best Soil Mix For Growing Cannabis

Many ingredients and components can help enrich your cannabis soil mix. However, some are better than others. This simple yet effective cannabis soil mix will help your plants grow and produce great yields of cannabis. It also helps you avoid certain ingredients that take months or years to properly break down.


  • 4 parts base soil
  • 1 part coco coir (or peat moss as an alternative)
  • 1 part worm castings
  • 1 part perlite or vermiculite
  • 2.5% guano
  • 2.5% bone or blood meal

Start by adding your four parts of base soil to a large container and breaking it up. You might want to use four parts of organic soil or combine regular potting soil with organic soil. Break the soil up thoroughly so you can add the other ingredients and mix them into the soil successfully.

Top your soil base with worm castings followed by coco coir. Rinsing and buffering your coco coir will help improve your soil. You can also use peat moss as an alternative. Next, top the soil mix with perlite or vermiculite, followed by guano then blood meal or bone meal. This should give you an excellent soil mix for growing your cannabis plants.

How To Use Your Cannabis Soil Mix

Your homemade cannabis soil mix will be extremely rich in nutrients and other valuable components for growing your cannabis plants. However, while this is excellent for helping your plants flower, you shouldn’t plant your cannabis seeds or clones directly into your cannabis supersoil.

Cannabis seeds and clones are very fragile and exposing them to these nutrients too early can cause nutrient burn and ruin their growth. As such, you’ll want to initially plant your seedlings or cuttings in neutral soil for the first few weeks. Once they’ve rooted and grown three or more nodes with well-developed leaves, you can transplant them into your super soil.

This is also helpful as it gives you more time to prepare your supersoil before the planting process. It helps to soak your cannabis soil mix with purified water for a couple of days before you plan to transplant your plants into it. That way, it will be cooler and it can also help get rid of pests and other problems. Allow your soil to dry before transplanting and use regular water for the first few waterings after adding your cannabis plants.

How To Use Your Cannabis Soil Mix


This nutrient-enriched soil mix will give your cannabis plants the nutrients they need to grow beautiful cannabis buds. You can end up with an impressive yield of high-quality weed that you’ve cultivated and harvested from the comfort of your home. You can then continue the process with more plants.
