To till your soil, apply the amendments and start digging or use a rototiller. It takes time, but make sure everything is adequately mixed, including all corners of a pot or bed.
Growing cannabis organically allows growers to produce a high-quality product without the interference of chemical nutrients that can burn or kill the plants. It’s important to truly understand what you want in your soil so you can produce your own custom blend that costs less and contains all essential nutrients.
Step 3: Mix your soil
To remedy this problem, you can submit a soil test to get a base understanding of what nutrients it contains.

However, by tilling every year, you can easily add amendments and break down cover crops, making sure all nutrients in the soil are mixed and readily available.
Their Ocean Forest soil mix is “hotter” soil (higher levels of nutrients) that contains ingredients that cannabis plants love, including earthworm castings, bat guano, fish meal and crab meal. The nutrients contained in the soil will provide everything your plant needs for several weeks. Although it might give young seedlings just a touch of nutrient burn at first, they can be started in Ocean Forest soil and will soon be able to use the nutrients and start growing quickly. Some growers might put a little big of Happy Frog on top of a container of Ocean Forest, just to make it a little more gentle for seedlings the first week or two.
Note: Don’t worry, there’ll be examples of good and bad soil in just a bit!

Good Cannabis Soil
Another light, rich soil mix with great drainage. Although there is a wood chip in this picture, for the most part the mix is completely composted and broken down. It’s normal to see some wood pieces in composted soil, but you don’t want to have to wait for a lot of wood to break down while your plants are growing – you want all that rich nutrient goodness to be readily available to your plant roots
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?
Texture, Drainage & Water Retention
If you get the soil part right, you have almost everything you need to get to harvest! With the correct texture, drainage and water retention, you’ve got a perfect base. Add good soil cannabis nutrients, especially in the budding phase, and you should get to harvest with great results!
Add water to mix and stir it in to initiate the microbial process. Super soil should be moist but not soggy while composting. The idea is to keep the mix both moist and relatively contained. If your super soil mix is not put in a container or wrapped up, it will dry out, which stops the whole process. Make sure you wrap up your soil if in a tarp, or put a top on your garbage cans. You need to keep the mix in a relatively enclosed environment.
How to Compost Your Own Super Soil!
With super soil, you’re re-creating the environment that causes cannabis to grow like a weed in the wild. You’re creating a “living soil” that acts a lot like the most fertile types of soil in nature.
For growers who want more contol over the exact nutrients and supplements delivered to the plants, than this can be a great option.
Another cool thing is you use a smart pot exactly the same as a regular pot, and still get those benefits.
If you don’t have a big enough container, use a tarp or even a kiddie pool
When using amended and composted super soil (like this recipe by Subcool), you are creating an entire soil ecosystem that extracts organic nutrients in their natural form and makes them available in a form that your plants can easily use.
