Mammoth P Active Microbials

Maximize Your Growth Potential

Mammoth P is the product you need to maximize phosphorus cycling. Boosting your phosphorus cycling can increase growth and yield! Plus, Mammoth ensures that every Mammoth product delivers huge benefits.

Mammoth Benefits

Maximized Phosphorus

Keep internodes shorter and focus energy on plant growth.

Beneficial Bacteria

The bacteria in Mammoth P acts like tiny bioreactors that continually release phosphorus, without the need for a separate additive – allowing you to carry on worry free.

Protects Your Rhizosphere

The science in Mammoth P outcompetes potentially harmful pathogenic microbes, shielding your plant’s rhizosphere.

Safe for All Media and Fully Compatible

Mammoth P is safe for use as a supplement to any fertilizer program in soil, soilless, and hydroponic systems.

Tried and Tested

  • 16% Increased Average Yield
  • 6% Increased Stem Strength
The technology in Mammoth P has been extensively tested by growers and farmers across the world. We have worked with leading US academic institutions and independent labs who have proven that Mammoth P can deliver increased growth.

How It Works

Mammoth P was developed by screening billions of soil microorganisms in search of those that most efficiently release phosphorus and make it available to plants. The proprietary trait selection platform assembled a consortium of soil bacteria that are 30x more effective at phosphorus cycling than naturally occurring microbial communities! More phosphorus can provide greater growth.

What Makes Mammoth P Different?

Phosphorus Cycling Process

Mammoth put a strong focus on phosphorus cycling processes to ensure the release of soil P and micronutrients – improving phosphorus availability for your plants.

High-Throughput Platform

Our platform allows us to select soil microorganisms at the community level in hydroponic environments. What does that mean for you? A consortium of bacteria that work equally well in soil, soilless, and hydroponic systems.

Directed Phenotyping

Other products use a non-directed approach to phenotyping. With Mammoth P, you know you’re getting a handpicked, highly effective product with proven provenance and functionality.

Enzyme Structure

Mammoth P's bacteria act as micro-bioreactors, constantly producing a more diverse suite of enzymes that enhance phosphorus availability than the leading enzyme-specific products.

Works in All Media


Mammoth P contains microbial nutrition that is extremely effective in boosting the growth of your plants. This is because the beneficial bacteria in Mammoth P are able to cycle more phosphorus in the plant-root system.


We’ve carefully selected and cultivated microbes and phosphorus nutrients that thrive in hydro environments.

Super Soil

The microbes in Mammoth P are very effective at mineralizing the slow-release phosphorus that’s found in many ‘all-in-one’ water-only soils.

Directions for Use:

  • Shake bottle well before each use
  • Mix with water following the weekly application rate

General Use / Purpose of Product:

Mammoth P is specifically designed to increase phosphorus availability during the bloom phase and should be used as a supplement to your regular fertilization program. Application during clone and vegetative phase will boost effectiveness. Mammoth P has a near neutral pH formulation and runs clean in any system.
