How 5E9 Probiotic Soil Inoculant works for your plants
  • Nourishes the soil microbiome to improve nutrient availability, so roots can uptake more efficiently and support healthy shoot development.
  • Supports nitrogen cycling in the rhizosphere, contributing to stronger, more resilient plants even in marginal soils.

  • Provides a natural line of defense by fostering a beneficial microbial community that can deter common soil-borne pests and diseases.

  1. During every other watering, apply 1/2 teaspoon per gallon of water from the start of growth through mid-flower to introduce and maintain the beneficial population in the root zone.
  2. At transplant, apply directly to the roots to jump-start colonization and accelerate establishment in fresh media.
  3. Continue using at the 1/2 teaspoon per gallon rate on the irrigation schedule that aligns with your growth stage to sustain microbial activity.
