Growing cannabis organically means cultivating the herb as nature intended. Native cannabis strains—or landraces—thrive in the wild all over the world. This goes to show that high-quality soil and biodiversity are all it takes to support the growth of thriving plants.

Sure, the cannabis industry has developed many synthetic formulas and techniques, and with great results. But we believe the best-quality flowers and the healthiest plants emerge when we go back to our roots.

Much like alchemy, organic cannabis cultivation involves turning low-value or waste products into high-value resources. Not only does growing cannabis organically result in incredible harvests, but it benefits our gardens and the environment, too.

PERFECT ORGANIC SOIL FOR CANNABIS

High-quality organic cannabis depends on one major factor: soil health. The last few decades have seen growers apply one nutrient for one problem—somewhat of a reductionist view. More recently, advancements in soil science have shown us that cannabis plants rely on a complex interplay within the soil—the soil food web—to stay healthy and thrive.

THE SOIL FOOD WEB AND PLANT INTELLIGENCE

The soil food web consists of many microorganisms, insects, and even birds and mammals. These creatures—many acting as both predator and prey—play an important role in breaking down organic matter into nutrients that are accessible to cannabis plants.

Starting off your growing operation with healthy living soil will help you avoid potential nutritional deficiencies, pest issues, and plant pathogens further down the line. Contrary to popular belief, plants don’t just suck up nutrients straight from the soil.

Instead, they farm their own food (literally!). They do so by releasing sugars (exudates) into the rhizosphere—an area that extends around two millimetres from the surface of the root system—attracting beneficial bacteria and fungi. Some of these organisms team up with the roots, allowing plants to better absorb nutrients, whereas other microbes act as food for larger creatures.

Nematodes and protozoa—the next step up in the soil food web—eat some of these microbes. It just so happens that bacteria and fungi are very efficient at breaking down organic matter and storing the nutrients locked up inside.

Nematodes and protozoa poop out some of these molecules. The plants then feed on these bioavailable nutrients, harvesting the bounty of their farming operation. Simply amazing, huh?

THE SOIL FOOD WEB AND PLANT INTELLIGENCE

KEY PLAYERS

But plants don’t just make food through this interplay. The organisms they attract also help to shape the soil and keep it in optimal condition for healthy growth. Check out some of the most important soil food web lifeforms below:

Bacteria: These tiny creatures produce slimy substances that keep soil particles stuck together and give the growing medium structure. They also serve as food for larger lifeforms that excrete plant food.

Fungi: Fungi produce net-like structures (mycelium) that give the soil shape and keep it from crumbling or washing away. Beneficial “mycorrhizal” fungi also link up with plant root systems to improve nutrient uptake.

Nematodes: They gobble up smaller lifeforms and free up nutrients into plant-available forms. Certain “good” nematodes also keep the “bad” ones away (the latter like to chomp on plant roots).

Protozoa: These guys graze (like tiny little cows) on bacteria in the soil. Not only do they excrete free nutrients, but their hunting encourages the bacterial population to respond by growing faster.

Worms: Chill out, we’re not asking you to bring worms into your grow room! But, worms are so important in the soil. They take nutrients down into the medium, and their tunnels help to aerate and bring water down to plant roots.

Using organic practices in your cannabis garden will support microbial life and improve soil year after year. Learn what you need to know in our complete guide!
