Another way in which these microorganisms benefit your grow is by breaking down nutrients and micronutrients and making them more readily available to your plants through the production of chelators. Plus, there are several strains of bacteria that supply your plants with growth and bloom cofactors to further increase branching, budding and flowering sites.
However, by increasing the size of your root mass, you’ll increase your plants’ capacity for nutrient storage and energy production. In other words, bigger, more expansive roots mean bigger, more productive cannabis.
Promoting Cannabis Root Growth With Microbial Nutrients
There are several factors that play into root growth, including temperature, moisture levels and the availability of oxygen. That’s right — your crop’s roots need oxygen, even though the upper portion of the plant utilizes carbon dioxide. This is why it’s critical to have proper airflow into the root zone.

Additionally, beneficial microbes can increase the production of essential oils within your plants.
For example, even though they can coexist in a root-zone environment, some beneficial microbial strains are incompatible when bottled together in a concentrated solution, which means the manufacturer must know which strains and species are incompatible to bottle them separately so that the microbial populations are preserved within the packaging.

You’ll also want to ensure the supplement you choose has the largest number of live microbes possible. Beneficial bacteria and fungi are only beneficial if they’re alive — which means they have to be packaged in a specific manner.
Here’s how you can stimulate expansive root growth in your cannabis plants — which means bigger crops — by utilizing the power of beneficial microbes.
These sugars, in combination with oxygen taken in by the roots, create ATP energy for the plant. ATP energy, in combination with nutrients pulled from the soil, ensures that the plant grows vibrantly.
The photosynthesis process kicks off when water touches a plant’s roots. Water, carbon dioxide, and stored sunlight then work together to produce sugars necessary for growth in the plant.
Spreading mulch or hay around the base of your plants can also help regulate temperature, but be sure to keep a 6-inch radius around the stalk of each plant free, as excessive moisture in the mulch can lead to rot if it touches the stalk.
- Let soil dry in between waterings. When soil is saturated, it can’t breathe effectively; as it dries up, the roots pull oxygen in. Dry periods between waterings are essential for oxygen absorption.
- Use a smart pot. These pots are made of a porous material that allows oxygen to seep in through the sides. Plants buried in the ground or in hard pots are limited to intaking oxygen from the surface.
- Perlite, vermiculite, and peat moss. These materials help fluff up soil, giving more space for oxygen to flow through and to keep soil from compacting.
- Use complete soils. These promote life for fungus, insects, and microbes that help keep soil loose, allowing for the development of root networks throughout the soil.
Roots are active at night and happiest around 75°F (24°C). With an indoor setup, a good tip is to set up your air intake below the canopy and your exhaust above the canopy to keep a fresh, healthy cycle of air.
To see if a pot is too small, observe the roots from the drainage holes of the pot—if you see roots crossing over the holes, then it’s time to transplant it to a bigger pot.
This symbiotic relationship—called mycorrhiza—is important in keeping roots healthy so they can access all available nutrients.
If growing outdoors, growing a cover crop—like clover—with your cannabis plants can keep soil temperature more consistent, while also protecting the topsoil layer.
Roots need plenty of space as they grow out and explore for water, oxygen, and nutrients. When cramped, a plant’s root system can strangle itself, becoming root bound. Roots can begin to die off and root rot can set in, possibly killing the plant entirely.
A healthy plant has healthy roots. This guide shows you how to avoid problems like root rot by keeping your cannabis roots healthy & strong.
