Unleash your plant’s full growth potential with MAMMOTH P. MAMMOTH P is a university-tested patent-pending microbial biostimulant that naturally elevates phosphorus and micronutrient availability to support healthy vigorous plant growth.

For use during vegetative and flowering stages in all media – from hydroponic to organic potting mixtures to soils. MAMMOTH P utilizes a consortia of natural beneficial soil bacteria that liberate phosphorus and other nutrients into a form that plants can efficiently utilize. This results in more efficient use of fertilizer and soil nutrients by plants.

University-testing has demonstrated faster, more vigorous, and more consistent growth for a variety of plants- from turfgrass to vegetables to medicinal botanicals. Use with every watering, or with each reservoir fill through the blooming stage. Shake well before each use and never mix concentrates.

MAMMOTH P from Growcentia can be used in conjunction with any nutrient formula and is safe with all pH buffers.  Using innovative proprietary technology, this phD driven team developed an approach to identify and apply nature’s very best microbes to improve nutrient availability to plants resulting in a 16% increase in your yield.

The premier natural solution for any soil or hydroponic system.

Mammoth P will definitely help with a better yield, AND quality.  Mammoth P makes the phosphorous that you feed your plants more available to the plant to increase uptake of phosphorous and micronutrients.  This increases the overall health of the plant and allows more oil production and a much better yield.  It is also organically certified.

This concentrated formula is offered in the following sizes: 250 ml, 500 ml, 1 liter, 4 liters and even 5 gallons!

Mammoth P Key Highlights

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 growth by independent labs. This is a must have organic fertilizer!

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

Fully Compatible – For use as a supplement to any fertilizer program.

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