The Process to Create Organic Soil For Your Cannabis Plants: A Quick Guide


Experienced marijuana growers would agree that organic soil is the most basic step that decides weed’s taste, aroma, and potency. Now, you may ask, does not seed matter? Of course, it does, but healthy soil ensures that the strain fulfils its potential.

Trust me; a well built, healthy organic soil is good for your buds and the planet. In this quick guide, let me share all about organic soil and how to prepare the best organic soil for your marijuana cultivation.

What Defines Healthy, Organic Soil?

A forest would be the best metaphor to understand this. Picture a rainforest—a vibrant ecosystem filled with a variety of different creatures. Bird calls and sounds of insects permeate the air. It is bountiful with biodiversity. Life thrives in every atom.

Now, what do you see if I ask you to imagine a monoculture plantation? It is growing only one type of tree. It has no diversity, and thus, you would hear very few birds and perhaps, ever lesser insects. These plantations are silent, vulnerable to disease and infestation.

The soil of the rainforest is packed with vital life forces.

Micronutrients, bacteria, fungi, and various other organic components enrich the soil, making it healthy. To make your marijuana plants happy, you need to provide soil bubbling with life force.

A basic mixture of soil devoid of organic components will not provide your plants with the nutrients it needs. They will suffer. You can also buy high-quality organic soil.

Cannabis, like all plants, evolves in sync with a diverse ecosystem. They thrive well in tandem with other kinds of life. If you only pay attention to the soil, you can produce a premium harvest of cannabis buds instead of normal potting soil, which might grow lackluster cannabis that does not reach its full potential.

What Is Organic Living Soil?

Are you wondering about the living aspect of the organic soil? Well, marijuana develops a beautiful and intimate interconnection with its surroundings.

The cannabis plant creates an intricate root network that soaks up nutrients, water, and oxygen and relates with microorganisms like bacteria and fungi living in the soil. You can make your plant’s process of absorbing resources from the soil by creating a healthy population of bacteria and fungi.

A thriving community of microorganisms in the soil is essential for the wellbeing of your marijuana plant. Some fungus and bacteria can also help your plant baby to defend against pests and diseases.

This microscopic support system can be created easily by adding soil amendments. Worm castings and bat guano enhance the growth of healthy bacteria. For fungus supporting your plants’ growth, opt for kelp meal, Mycorrhizal inoculant or humic acid.

Cannabis Plants Favorite Soil Texture

The physical structure and its texture are very important for the flourishing harvest of your dreams. If you enjoy digging your hands in the dirt, you are in luck, or else, you must learn to enjoy. Test soil on your fingers. How does the soil feel? Does it feel sandy, or is it like clay? Is it loose, airy or thick?

The texture and physical structure of the soil would let you understand how well aerated and drainage prone your soil is.

pH Level Appropriate For Cannabis Growth

Digital readers and pH test strips will determine the soil’s pH level. Aim to keep it between 6 to 7, as marijuana plants prefer slightly acidic soil.

You can adjust the soil’s pH level by using pH level up or pH level down soil amendments.

Fundamental Building Blocks Of Organic Soil

Aerator, Organic Compost and Organic base build up the fundamental building blocks of organic soil.

Natural humus or Coco Fiber can be used for the organic base material. It holds up the other components of the soil.

True to their name, aerators aerate the soil by making the texture porous, enhancing the drainage and supporting great root development. Perlite or vermiculite can be used as aerators.

Decomposed organic wastes comprise organic compost. These wastes can be kitchen waste, decomposed leaves or any such organic waste.

You need to mix equal portions of all these to build your soil from scratch. If you live in an area with marijuana cultivation, try to source local soil where these plants are already growing.

After the base material, some more components should be added to your soil to ensure a diverse ecosystem thriving in it. This would meet the nutrition needs of your cannabis cultivation. Any organic soil mixture has these ingredients like pumice, coco fibre, perlite, peat moss, kelp, premium worm castings, bat guano, fishbone meal, soybean meal, feather meal, greensand, leonardite, alfalfa meal, and leonardite.

Specific Soil Component Needed For Cannabis

Cannabis has certain specific requirements from the soil. Coco fibre, humus and peat improves the physical structure of the soil and drives a thriving harvest.

The pH level of the soil and its texture is improved through these.

Organic Nutrients That Promote Marijuana Growth

Similar to all living beings, plants require nutrients for their growth and survival. Cannabis plants require micronutrients in addition to macronutrients for their well being.

You need to opt for nutrients particularly created for cannabis while creating a suitable soil profile for your marijuana babies.

These nutrients are N-P-K or nitrogen, phosphorus, and potassium mixed in certain ratios. The requirement of this ratio differs for every phase of growth.

Let us have a look

Phase of Growth N-P-K Ratio


Clone or Seedling Stage 5-3-4
Flowering Stage



Vegetative Stage




Here are some soil amendments that promote these nutrients in the soil.

Soil Amendments


●      Bat Guano

●      Worm Castings

●      Crustacean meal

●      Bone meal

●      Chicken manure

●      Glacial Rock


●      Wood ash

●      Compost

●      Seaweed meal

●      Potassium



Suppose all this sounds too complex for you. Don’t Worry! You can buy nutrient kits specially designed for cannabis to maintain the correct ratio of all these macronutrients in your soil. They will prevent your plant from getting malnourished, and you can chuck away the need for trial-error and guessing the correct ratio.

You might want to check out The Nutrient Organic Pack at the top online seed bank and store i49. It has a wonderful blend of organic nutrients that are formulated especially for each phase of growth. While feeding, start with less than the recommended dose and slowly increase depending upon the growth.

Read the labels and get acquainted with the nutrients and their percentage. While you do that, gradually start learning about the nutrients and observe how your plant responds to them. In time you will build up your knowledge of organic soil.

As you slowly start getting used to using these nutrition kits, experiment with these ratios and supplements. You will gradually start becoming comfortable with making an organic soil mix that would support your plant to grow a fragrant, resinous harvest.

Required Micronutrients For The Cannabis Plant

You also need to pay attention to the micronutrients for a lush harvest.

These micronutrients are:

  • Sulphur
  • Iron
  • Calcium
  • Magnesium
  • Zinc
  • Manganese
  • Copper

These might be too much to remember. But do not worry. There is good news. When you prepare the soil using organic components, these micronutrients will already be present in the soil. In time, you will understand your soil better and fine-tune the quantity of these micronutrients.

You can also work with secondary soil amendments like a blend of calcium and magnesium. Experiment a bit and observe what effects these tiny adjustments have on growth and flowering.

Closing Thoughts

So, now that you are equipped with all the information you need to create super-rich organic soil for your plants, what are you waiting for?

Get going. Mix up soil that is an all-natural and happy home for your plants.
