In the Bible’s Exodus 16, Manna refers to the food miraculously supplied to the Israelites in the wilderness. Our Microbe Manna™ Dry prebiotic was developed using years of research into soil health and the best nutrients for growing healthy soil and plants. 

This one-of-a-kind blend supports the entire soil food web, starting at the bottom or first trophic level and working its way up to create living organic soil. Microbe Manna™ Dry is specially formulated to create soil with balanced nutrition, creating an environment that supports unparalleled soil fertility, explosive proliferation, and incredible overall plant health.

Strong and healthy plants are like professional athletes – they require the right food and conditioning to win. Microorganisms are the foundation of healthy soil and are critical to ensuring that your plants receive the proper nutrients to grow and thrive.

Microbe Manna™ Dry works best when used with Microbe Manna™ Flora and Microbe Manna™ Liquid. For sandy soil or soils requiring higher levels of water retention, we recommend adding Microbe Manna™ Hydrate.


  • Offers focused soil nutrition and rapid microbial proliferation
  • Helps to rapidly build and maintain the soil food web
  • For use in all types of soils and soilless media
  • Works with all feeding regimens

I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
