Who This Is For

  • You are adding a microbial inoculant because your root zones struggle to convert base nutrients effectively.
  • You are introducing beneficial bacteria because your media moisture levels fluctuate and cause regular plant stress.

What We Found

  • We find this formula stays suspended in reservoirs much better than the thick, sludge-like inoculants from rivals.
  • The low 1.25 ml per litre dose makes this one of the most cost-effective ways to protect a large scale crop.
  • Root mass shows a visible increase within just seven days of adding this to a standard liquid nutrient programme.

What Users Say

  • Growers tell us their plants bounce back faster from dry spells because the microbes help the media hold moisture.
  • Users who switched to Root Builder say they stopped seeing the leaf yellowing usually caused by early root stress.

GreenPlanet Nutrients Root Builder

A high-performing plant starts from the bottom up. GreenPlanet Nutrients Root Builder is a professional-grade root zone inoculant formulated with specific beneficial bacillus bacteria to create a massive, healthy root system. By introducing active microorganisms into the rhizosphere, Root Builder ensures your plants have the biological support needed to maximize nutrient conversion, especially when paired with a base system like GreenPlanet Dual Fuel 1 & 2, and defend against environmental stressors throughout all stages of growth.

The strength of the Root Builder formula lies in its concentration of Bacillus licheniformis and Bacillus subtilis. These organisms act as a microbial soil amendment, breaking down complex elements into plant-available forms and producing natural iturins that target harmful microorganisms. Whether you are in the vegetative stage using GP3 Grow for vigorous foliage or in mid-bloom aiming for intense fruiting with Massive Bloom Formulation, this inoculant improves soil structure and moisture retention to deliver "bigger roots for bigger fruits."

CFIA Registered (No. 2019125A).

FAQ

What exactly are the beneficial bacteria in Root Builder? +

Root Builder contains two primary strains: Bacillus licheniformis, which helps break down nutrients, and Bacillus subtilis, which focuses on boosting natural defenses and protecting the rhizosphere—a process further supported by additives like Plant Guard.

Can Root Builder be used in hydroponic systems? +

Yes, Root Builder is effective in all grow media. It works as a microbial amendment that improves nutrient uptake and root health regardless of your specific cultivation method.

How does Root Builder help with pH issues? +

The beneficial organisms in Root Builder interact with the grow media to improve soil structure and biological balance, which can help treat and stabilize pH-related issues at the root level.

Do I need to use this during the flowering stage? +

Absolutely. While it builds a strong foundation in veg, continuing use through flowering ensures the plant can efficiently convert nutrients for intense fruiting and maintain a healthy root zone until harvest.

What is the recommended application rate? +

Apply GreenPlanet Nutrients Root Builder at a rate of 1.25 ml per Liter (or 5 ml per Gallon) alongside your regular nutrient solution, such as the 1-Part Medi One Starter Kit, for best results.
