Mammoth P


MAMMOTH? P is an organically derived microbial inoculant for growing plants that maximizes phosphorus and micronutrient cycling to maximize bud growth, increase yield, and enhance plant health. This technology has been extensively tested by growers and farmers around the world and by leading US academic institutions and is proven by these institutions and independent labs to increase growth.

Increased Average Yield – 16%

Increased Stem Strength – 6%

University Developed

Developed by Growcentia?s founders at a leading US university using next-generation technology. Extensively tested by Colorado growers, and proven to increase plant growth by independent labs.

Beneficial Bacteria

Our beneficial bacteria act like micro bioreactors, continually producing enzymes that release nutrients. Reduces the need for a separate enzyme additive.

More Phosphorus

Increased levels of phosphorus keep internodes shorter and focuses energy on bud production.

Safe For All Media

Safe for use in soil, soilless, and hydroponic systems.

Protects Rhizosphere

Shields the plant rhizosphere by outcompeting potentially harmful pathogenic microbes.

Fully Compatible

Use as a supplement to any plant fertilizer program.

How They Did It:

“We developed Mammoth? P by screening billions of soil microorganisms to identify those that most efficiently release bound phosphorus in soil and other growing media, and make it available to plants. Using this proprietary trait selection platform ultimately resulted in a consortium of soil bacteria that are up to 30x more effective than microbial communities found in nature at releasing bound soil Phosphorous for plant absorption.” – Mammoth P Researchers
