Developed by PhD soil microbiologists and university-tested, it increases average yields by 16% and stem strength by 6%. Compatible with soil, soilless, and hydroponic systems, Mammoth P enhances bud growth and overall plant health while promoting sustainable agriculture. ## Description Product description Not your average microbe. What makes MAMMOTH P different? No.1 Nutrient cycling process Our development platform focuses on nutrient cycling processes to release soil P and micronutrients from bound forms, thus improving nutrient availability to plants. No.2 High-throughput platform Our high-throughput platform allows us to select soil microorganisms at the community level in hydroponic environments – which enables these bacteria to work equally well in soil, soilless, and recirculating hydroponic systems. No.3 Directed Phenotyping Our directed microbial phenotyping platform – coupled with cutting-edge high-throughput molecular techniques – is highly effective. Many competitor products use a non-directed approach by simply mixing microbes, which results in a microbial concoction of unknown provenance or functionality. No other microbe is like a MAMMOTH Microbe. We take no short cuts. Before releasing a product, we extensively test all our products in the lab, greenhouse, and field to ensure efficacy. New products will only be released if they meet our stringent standards. MAMMOTH WAS FOUNDED BY A TEAM OF THREE PHD SOIL MICROBIOLOGISTS WHO SHARE A PASSION FOR ENHANCING SOIL HEALTH AND PROMOTING SUSTAINABLE AGRICULTURE.MAMMOTH AIMS TO HELP CULTIVATORS ENHANCE PLANT HEALTH WITH A FAMILY OF PRODUCTS THAT INCLUDE ORGANIC MICROBIAL ADDITIVES AND ALL-NATURAL PESTICIDES. Directions Add Mammoth P to your nutrient solution during the vegetative and flowering stages. Apply consistently according to the recommended dosage for your growing medium. Monitor plant growth and adjust application as needed to maximise phosphorus uptake. Store properly to maintain the product's efficacy. Review: Mammoth P kicks Ass - Works great from clones to flower great mulit use product orgamic. Review: Works as advertised ! - Absolutely love it!! ## Features - Harmful if swallowed. - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01CBTYRJ2 | | Best Sellers Rank | 568,631 in Garden ( See Top 100 in Garden ) 2,211 in Hydroponic Nutrients & Additives | | Brand | Mammoth | | Brand Name | Mammoth | | Coverage | 1 | | Customer Reviews | 4.6 out of 5 stars 172 Reviews | | Global Trade Identification Number | 00851015006019 | | Item Form | Liquid | | Item Weight | 2 Pounds | | Item form | Liquid | | Item weight | 2 Pounds | | Liquid Volume | 500 Millilitres | | Liquid volume | 500 Millilitres | | Manufacturer | Mammoth P | | Model Number | 4224758031 | | Number of Items | 1 | | Part Number | 4316245717 | | Specific Uses For Product | Plant Growth, Soil Conditioning, Root Development, Flowering Enhancement | | Specific uses for product | Plant Growth, Soil Conditioning, Root Development, Flowering Enhancement | | UPC | 851015006019 | | Unit Count | 500.0 millilitre | ## Product Details - **Brand:** Mammoth - **Item weight:** 907 g - **Item form:** Liquid - **Coverage:** 1 - **Liquid volume:** 0.5 Litres ## Images ![Mammoth Mammoth P 500ml - Organic Microbial Inoculant for Plant Nutrient Efficiency, Bloom Booster, Fertilizer - Image 1](https://m.media-amazon.com/images/I/612ON+9ljYL.jpg) ![Mammoth Mammoth P 500ml - Organic Microbial Inoculant for Plant Nutrient Efficiency, Bloom Booster, Fertilizer - Image 2](https://m.media-amazon.com/images/I/91JrFnw02OL.jpg) ![Mammoth Mammoth P 500ml - Organic Microbial Inoculant for Plant Nutrient Efficiency, Bloom Booster, Fertilizer - Image 3](https://m.media-amazon.com/images/I/81ehlr1HyOL.jpg) ![Mammoth Mammoth P 500ml - Organic Microbial Inoculant for Plant Nutrient Efficiency, Bloom Booster, Fertilizer - Image 4](https://m.media-amazon.com/images/I/81LVXmNpg-L.jpg) ![Mammoth Mammoth P 500ml - Organic Microbial Inoculant for Plant Nutrient Efficiency, Bloom Booster, Fertilizer - Image 5](https://m.media-amazon.com/images/I/81avuMAhsNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Mammoth P kicks Ass *by A***R on 9 June 2026* Works great from clones to flower great mulit use product orgamic. ### ⭐⭐⭐⭐⭐ Works as advertised ! *by A***Y on 23 April 2026* Absolutely love it!! ### ⭐⭐⭐⭐ Good Stuff *by M***A on 13 March 2026* Does what it says --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/66907991-mammoth-mammoth-p-500ml-organic-microbial-inoculant-for-plant-nutrient](https://www.desertcart.jp/products/66907991-mammoth-mammoth-p-500ml-organic-microbial-inoculant-for-plant-nutrient) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-19*
