  4. Eco-Friendly: Living soil conserves water and eliminates the need for flushing before harvest. It’s a win-win for both the environment and the cultivator.

What is Living Soil Made Of?

At its core, living soil is a blend of organic components, each playing a crucial role in creating a fertile environment for plants, especially cannabis. Let’s delve deeper into the primary ingredients and the vital amendments that make living soil cannabis a powerhouse for cultivation.

Base Ingredients:

  1. Peat: Often sourced from ancient, waterlogged bogs, peat is a dense, spongy material that provides excellent water retention. It’s rich in organic matter and offers a slightly acidic pH, making it ideal for cannabis cultivation.
  2. Compost: Think of compost as nature’s black gold. It’s a rich, dark, crumbly substance made from decomposed organic matter. Compost introduces beneficial microbes to the soil and acts as a slow-release fertilizer, providing plants with a steady supply of nutrients.
  3. Coco Coir: Derived from the husk of coconuts, coco coir is a sustainable alternative to peat. It’s excellent for moisture retention and provides a neutral pH. Moreover, its fibrous nature promotes root aeration, ensuring that cannabis roots get enough oxygen.
  4. Worm Castings: These are essentially earthworm droppings, and they’re as magical as they sound. Worm castings are packed with nutrients, enzymes, and beneficial microbes. They enhance soil structure, improve moisture retention, and offer a buffet of nutrients for plants.

Key Amendments:

  1. Wood Ash: A byproduct of burned hardwood, wood ash is alkaline in nature. It’s used to raise the soil’s pH, making it less acidic. Additionally, wood ash is a good source of potassium, an essential nutrient for cannabis flowering.
  2. Green Manure: This isn’t manure in the traditional sense. Green manure refers to specific plants, like clover or alfalfa, that are grown and then tilled back into the soil. They decompose, enriching the soil with organic matter and essential nutrients like nitrogen.
  3. Kelp Meal: Derived from dried seaweed, kelp meal is a treasure trove of micronutrients. It provides cannabis plants with growth hormones, vitamins, and trace minerals. Kelp meal promotes root development, boosts plant immunity, and enhances flowering.

How to Make a Living Soil for Weed

Crafting the perfect living soil for cannabis cultivation is similar to preparing a gourmet meal. Each ingredient and step is crucial, ensuring the final product is both nutritious and conducive for plant growth. Let’s delve deeper into the art and science of creating living soil.

1. Create a Base

The foundation of any good living soil lies in its base. This is where the primary components come together, setting the stage for a thriving microbial community.

  • Sphagnum Peat Moss (⅓ part): Sourced from peat bogs, this organic material is known for its water retention capabilities. It provides a slightly acidic environment, which is often preferred for cannabis cultivation. Moreover, its fibrous nature ensures good aeration, allowing roots to breathe and grow without hindrance.
  • Perlite (⅓ part): These are tiny white balls made from volcanic glass. Perlite is added to the soil mix to improve aeration and drainage. Its porous nature ensures that excess water drains out easily, preventing root rot and other moisture-related issues.
  • Compost and/or Worm Castings (⅓ part): Compost introduces a plethora of beneficial microbes to the soil, kickstarting the decomposition of organic matter. On the other hand, worm castings, the byproduct of earthworm digestion, are nutrient-dense and teeming with beneficial bacteria. Together, they enrich the soil, making it fertile and ready for planting.

2. Amend Your Soil

Once the base is set, it’s time to fine-tune the mix, ensuring it caters to the specific needs of the cannabis plant.

  • Kelp Meal: A powerhouse of micronutrients, kelp meal offers a range of benefits. It not only provides essential nutrients but also contains natural growth hormones that boost plant development. Whether it’s root growth or flowering, kelp meal ensures the plant has the necessary tools to thrive.
  • Wood Ash: If your soil is too acidic, wood ash can be a savior. It’s alkaline in nature and helps in raising the soil’s pH. Additionally, it’s a good source of potassium, which plays a pivotal role during the flowering stage of cannabis.
  • Other Amendments: Depending on the specific needs of your cannabis strain and the existing nutrient profile of your base, you might consider adding other amendments. Bone meal for phosphorus, blood meal for nitrogen, or lime to further adjust pH are just a few examples. The key is to monitor the soil and plant health and adjust accordingly.

3. “Cook” Your Soil

With the base prepared and amendments added, the final step is to let nature take its course.

  • Resting Period: After thoroughly mixing the base and amendments, spread the soil out in a large container or tarp. Cover it lightly to protect it from direct sunlight and heavy rain. This resting or “cooking” period is crucial. Over the next few weeks, the microbial activity will skyrocket. Microbes will start breaking down the organic matter, converting it into plant-available nutrients.
  • Monitoring: During this period, it’s essential to keep the soil slightly moist. Too much water can drown the microbes, while too little might hinder their activity. A light misting every few days is usually sufficient.
  • Ready to Use: After a few weeks, you’ll notice the soil has a rich, earthy smell, indicating it’s teeming with life and ready to use. The texture would be crumbly, dark, and loaded with nutrients, making it perfect for cannabis cultivation.

Three Tips for Growing Cannabis with Living Soil

  1. Start with Healthy Plants: A strong foundation is key. Opt for clones from a robust mother plant or start from seeds.
  2. Optimize Environmental Conditions: Monitor temperature, humidity, and CO2 levels. Ensure your plants have the best environment to thrive in.
  3. Develop Cultivar-Specific Recipes: Each cannabis strain has unique needs. Tailor your living soil to match the requirements of the cultivar you’re growing.

Super Soil vs Living Soil

In the world of organic cannabis cultivation, two terms often pop up in discussions: super soil and living soil. Both are organic growing mediums designed to provide plants with all the nutrients they need without the use of synthetic fertilizers. But what sets them apart? Let’s dive into the nuances of super soil and living soil to understand their differences and similarities.

Super Soil

Definition: Super soil is a heavily amended soil that’s been pre-enriched with organic nutrients. The idea behind super soil is to mix a variety of organic amendments and then allow them to “cook” or compost over a period, breaking down the nutrients to make them readily available for the plants.

Components: Super soil is typically made up of base soil (like potting soil) combined with a variety of organic amendments such as worm castings, bat guano, bone meal, blood meal, fish meal, and more. These ingredients are mixed in specific ratios to create a nutrient-rich medium.


  1. Nutrient-Dense: Super soil is designed to provide all the necessary nutrients for the entire growth cycle of the plant, eliminating the need for additional feedings.
  2. Simplicity: Once prepared, growers can just plant their cannabis directly into super soil and water it. The soil takes care of the rest.


  1. Preparation Time: Super soil requires a “cooking” period, which can last several weeks to months, before it’s ready for use.
  2. Less Flexibility: Since the nutrients are pre-mixed, adjusting for specific plant needs during different growth stages can be challenging.

Living Soil

Definition: Living soil is a dynamic ecosystem within the soil itself. It’s teeming with beneficial microbes, fungi, and other organisms that work symbiotically with the plant roots to break down organic matter and provide nutrients. Creating a live soil for weed.

Components: Living organic soil contains organic matter like compost, peat moss, and worm castings, but its magic lies in the living microorganisms within it. These microbes, including bacteria, fungi, and nematodes, form a symbiotic relationship with plant roots, aiding in nutrient uptake.


  1. Symbiotic Relationships: The microbes in living soil form a relationship with plant roots, enhancing nutrient uptake and protecting against certain pathogens.
  2. Sustainability: Living soil can be reused multiple times. With each grow cycle, the soil becomes richer as the microbial life continues to flourish.
  3. Improved Plant Health: The diverse microbial life in living soil can lead to healthier, more resilient plants.


  1. Maintenance: Living soil requires a balance to keep the microbial life thriving. This might involve occasional amendments or compost teas.
  2. Initial Setup: Creating a thriving living soil ecosystem can take time and might have a steeper learning curve for beginners.

While both super soil and living soil aim to provide an organic, nutrient-rich environment for cannabis cultivation, they differ in their approach.

Super soil leans towards a proactive approach, where the grower anticipates the plant’s needs and prepares a nutrient-rich environment in advance. It’s like setting up a buffet where the plant can access whatever it needs, whenever it needs. This method is particularly appealing to those who prefer a hands-off approach during the actual growth phase.

On the other hand, living soil creates a more interactive and evolving approach. It’s about nurturing an ever-changing ecosystem where the soil and plant grow and adapt together, creating a live soil for weed. This method resonates with cultivators who enjoy being continuously involved in the process, observing the symbiotic relationships, and making adjustments to maintain a thriving microbial community.


Living organic soil is more than just dirt; it’s a vibrant ecosystem that nurtures and nourishes. For cannabis cultivators, it offers a chance to go back to the roots, harnessing the power of nature to produce exceptional weed.
