MAMMOTH® P is an organically derived microbial inoculant for growing plants that maximizes phosphorus cycling to maximize growth and increase yield.

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.

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 releasing phosphorus. This reduces the need for a separate additive.

More Phosphorus
Increased levels of phosphorus keep internodes shorter and focuses energy on plant growth.

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.
