Description

Two named strains, working the root zone from opposite angles

Green Planet Root Builder introduces two specific beneficial bacteria strains to the growing medium: Bacillus licheniformis, which breaks down organic and inorganic material into forms the plant can use directly, and Bacillus subtilis, which defends the root zone by producing iturins that target harmful microorganisms. Together they function as a microbial soil amendment rather than a fertiliser, improving how efficiently existing nutrients convert into a form the roots can take up.

The result over time is better soil structure, improved moisture retention and reduced salinity-related stress at the root zone — all root health issues rather than single-nutrient deficiencies, which is why Root Builder is used as an ongoing addition rather than a one-off treatment.

Key Benefits

  • Two named beneficial bacteria strains — Bacillus licheniformis and Bacillus subtilis
  • Improves nutrient conversion efficiency from existing fertilisers
  • Builds soil structure and improves moisture retention
  • Bacillus subtilis produces iturins that target harmful root-zone organisms
  • Works in soil and hydroponic systems alike

How to Use

  • Apply at 1.25ml per litre in conjunction with the nutrient solution
  • Use consistently through the cycle rather than as a single application
  • Also useful as a starter or co-mix component for compost teas
