## Description

Mammoth P 500ml - Organic Microbial Inoculant for Plant Nutrient Efficiency, Bloom Booster, Fertilizer

## Features

- ORGANICALLY DERIVED MICROBIAL INOCULANT: Utilizing natural beneficial soil bacteria and microorganisms to liberate phosphorus and plant nutrients. This results in more efficient use of fertilizer and soil nutrients by plants to maximize bud growth, increase yield, and enhance plant health.
- UNIVERSITY TESTED AND DEVELOPED: MAMMOTH P Bloom Booster was developed by Growcentia’s founders at a leading US university using next-generation technology. Rigorously tested by Colorado growers, and proven to increase plant growth by independent labs.
- CONTAINS BENEFICIAL BACTERIA: Beneficial bacteria act like micro bioreactors! Live microbes release bound phosphorus in soil and other growing media 30x better than the average soil and continually produce enzymes that release nutrients reducing the need for a separate enzyme additive.
- GROW BIGGER BUDS WITH P: A microbial biostimulant that unlocks and converts phosphorus into soluble forms for plants to easily take up through their roots. Increased levels of phosphorus keep internodes shorter and focuses energy on bud production. 16% increased average yield. 6% increased stem strength.
- SAFE FOR USE IN SOIL, SOILLESS AND HYDROPONIC SYSTEMS: Great to use in soil, coco, rockwool, hydroponic systems, and any growing media. Fully compatible for use for use as supplement in any plant fertilizer program.
