Example of happy marijuana plants in good soil!
It’s easy to get caught up thinking about what nutrients and amendments are in the soil, and those are important, but perhaps the most important aspect of any soil is actually its texture, ability to drain, and overall water “holding” ability.
Signs of Good Cannabis Soil
Usually an organic potting mix does not have enough nutrients to last your plants for more than a few weeks, so it’s a good idea to always supplement with cannabis-friendly nutrients, especially in the flowering stage when your plant is making buds and needs lots of extra Phosphorus and Potassium.
Texture, Drainage & Water Retention

Leave the covered trash cans in a sunny location for 30 to 60 days. Continue watering the mixture during this period, always maintaining vital moisture without drenching it. This period of the composting process is called baking because the mixture will become hot to the touch as the sun bakes it. The heat emanating from the mixture breaks down the soil ingredients so the cannabis plants can absorb them. You may opt to add live worms to the mix, which will help aerate the growing medium and keep the soil healthy. Either way, mix everything one last time for good measure.
Once you’ve watered the mix, it’s time to bake it in the sun as you would do if you were making a compost. The cooking process breaks down all the component ingredients and prepares the soil for successful planting. As with generic super soil recipes, since you’ve added nutrients, there will be no need to fertilize. Simply transfer the Subcool super soil into large pots that can hold up to 10 gallons and start planting.
In the wild, cannabis plants grow freely like weeds. In a controlled environment, cannabis growth is altered and sometimes diminished depending on the quality of the soil used and any inorganic materials it may contain. But with super soil, you can mimic a wild environment to make your cannabis plants more fertile. Think of super soil as the closest possible growing medium to Mother Nature. Super soil is sometimes referred to as living soil because of how it recreates a natural growth environment for marijuana. This means less work for you as a cultivator, along with the potential for a larger yield of cannabis.

The next part of the process is composting, which will require up to 60 days to complete. Take a week to continue mixing the ingredients until they are fully blended and you don’t see any more pockets of color. The mixture should be an even earth-tone brown.
You can mix in a couple of ways. The first way, which is not recommended, is to simply mix everything together in a pile. Such a rushed approach will not permit the ingredients to blend properly, so we recommend a more layered and methodical strategy for the best results. Here is everything you’ll need to do in 12 steps:
Those five ingredients form the basis of your soil composting mix, but there are plenty of goodies that you can add to super soil to maximize its potency. Among these beneficial ingredients are bone meal, bat guano, and worm castings. All of these organic materials work with the nutrients already present in super soil to create a powerhouse recipe for cannabis growth. Earthworm castings and fish bone meal are especially powerful ingredients to blend into super soil. Consider mixing in this combination of supplemental ingredients:
Once you have completed all these steps, the final product will be an organic soil ready to use for indoor or outdoor cannabis cultivation. The recipe is appropriate for any type of pot and any size batch you wish to produce. You can also think of your creation as smart soil as it will be mostly maintenance-free.
