Unleash Root Inoculant and Biostimulant contains a proprietary blend of beneficial plant growth-promoting rhizobacteria (PGPR).


Works equally well in soil, soilless and hydroponic growing media, and it promotes higher yields by:


  • Unlocking Nitrogen, Phosphorous, and Micronutrients
  • Increasing Nutrient Availability for healthier and stronger plants
  • Improving Resistance to Abiotic Stress

Unleash root inoculant

Our Microbial Root Inoculant and Biostimulant will unleash your plant’s optimal growth potential!


For over ten years, Unleash Organics’ root inoculant has enabled farmers to unleash the full potential of their nutrient program by combining proven methods with cutting-edge growing technology .

“We love the simplicity of this product but also the power of this product as it Unleashes our root zone for our plants to maximize their potential”

207 Bonnie N Clyde Cultivators, Maine

I did a control test on 35 of my plants and found out that the buds were thicker and heavier. We had less air buds and the flowering time was cut down, meaning the plants matured more rapidly. Until now, I felt that my compost tea is so perfect. However to my excitement with Unleash, I got over 25 percent increase in weight, which translates into significant more product.

Very happy with Unleash Root Inoculant. Seeing a large increase in cannabinoids throughout two varieties of hemp. One hemp variety increased from 4% CBD to 8%, one variety from 8% up to 14-16%.

Why Use Unleash Root Inoculant and Biostimulant?

Promotes Nutrient Availability

Unleash root inoculant acts as a biostimulant, making nutrients available to plant roots in order to maximize its growth potential.

The Rhizosphere microbes in Unleash are able to digest fertilizers, making it easier for nutrients to be absorbed through the plant’s roots and allowing the plant to focus its energy on growing.

Prevents Root Burn

Root burn is a common problem for plants that requires a large amount of nutrients to obtain higher yields.

Unleash microbes digest nitrogen, phosphorous, and micronutrient fertilizers separating them from the attached salts that cause the root burn.

Many farmers have noted that adding our root inoculant to their current nutrient program assists in the chemical conversion of nitrogen and other nutrients into the form most desired by the plant.

This results in an easier uptake by the plant’s roots.

Eliminates Transplant Shock

A plant’s relationship with its local environment begins with the microbes that live on the roots and digest nutrients for the plant.

When you transplant, this microbe colonization of the plant roots is severely disrupted and has to be rebuilt before the plant can efficiently obtain nutrients.

With Unleash root inoculant’s microbes already present on the root system prior to transplant, the plants will be able to resume developing immediately after transplanting with no time lost.

Get rid of the hardships, inefficiencies, and lost growth time of transplanting with our root inoculant.

Promote Mycorrhizae Activity

Just like plants, mycorrhizae need help from rhizosphere microbes to get the nutrients they need to colonize and extend the plant root system.

Our microbes maximize mycorrhizae growth and ensure that the plant has a healthy and protected rhizosphere.

Works with Fertilizers, Compost Tea & Other Additives

Unleash root inoculant can be easily incorporated into your existing system with no complicated changes. In fact, our root inoculant works well with many other additives, and oftentimes enhances and improves the impact that your current additives have on your plant’s growth potential.

Works with Soil, Hydroponics, and Soilless Soil Media

Our root inoculant has been tested and shown to work with a large variety of grow systems. Unleash microbes will colonize the plant roots and immediately begin protecting and providing nutrients to the plant regardless of the system used.

The Biostimulant Technology Edge

root inoculant and biostimulant

Plants have a built-in “optimal” ability for healthy growth and high yield production. However, plants can fall short of optimal ability for some of the following reasons:


—  Insufficient nutrient uptake which can damage yields long before your plants start to produce crops


—  Biological stress such as pests or disease;


—  Abiotic stress such as root burn and drought. Using Unleash Root Inoculant can help prevent problems before they start by protecting against these challenges. See the science behind Unleash.


It takes a rigorous manufacturing process to achieve a stable mixture of plant growth-promoting rhizosphere (PGPR) microbes. One unique benefit of Unleash Root Inoculant and Biostimulant is our manufacturing process. It captures the wide range of essential microbial activities responsible for restoring balance to agricultural soils (crop roots) in a stable form with a long shelf life.


While our manufacturing process is proprietary, it is important to note that it is lengthy – taking several months from start to the final bottled products.


Containing a proprietary blend of beneficial plant growth-promoting rhizobacteria (PGPR), Unleash Root Inoculant works equally well in soil, soilless and hydroponic growing media promoting higher yields by:


  • Unlocking Nitrogen, Phosphorous, and Micronutrients
  • Increasing Nutrient Availability for healthier and stronger plants
  • Improving Resistance to Abiotic Stress
