Mammoth P delivers 16% yield increases, with 100% satisfaction guaranteed!

Many products can sound too good to be true, but occasionally there comes along an additive that does EXACTLY what it says on the bottle and much, much more. Mammoth P is one such product where the claims match the results. Plants can even perform one to two weeks ahead of schedule, cutting down your vegetative cycle and flowering times.

Mammoth P is the first organically derived microbial inoculant that maximises phosphorus and micro nutrient cycling to enhance plant health, resulting in increased vigour, stronger stems and superior growth. The results from using Mammoth P aren’t constrained to the vegetative cycle. Expect to see a 16% increase in yield and higher resin production, whilst maintaining a growers true No.1 objective… Quality!





  • Extensively tested by Colorado growers, and proven to increase growth by independent labs
  • Contains beneficial bacteria that act like micro bioreactors
  • Produces enzymes that break down locked-out phosphorus, making it available to your plants
  • Delivers increased levels of phosphorus, keeping internodes shorter and focusing energy on flower production
  • Peer-reviewed manufacturing process and product
  • Can be used in all media types soil, soilless (coco), passive and active hydroponic systems
  • Helps protect the rhizosphere, out-competing harmful pathogenic microbes
  • Works with any base nutrient
  • Doesn’t increase EC or PPM when used correctly
  • Has a near neutral pH
  • Runs clean in any system – no blockages
  • Fully accredited OMRI for organic use
  • One litre mixes into over 6000 litres of nutrient solution! A little goes along way





For those who are more technically minded lets dive into Mammoth P and answer many of the questions you may have. Mammoth P was created back in 2013 by a group of scientists working for Colorado state university to solve a big problem. How to feed the world sustainably. It's a big but very important question that needs an answer sooner rather than later. The researchers started to look at microbes to enhance crop yields. After much experimentation, soil samples and further microbe trials they came up with four microbes which they trust to boost yields.

  1. Pseudomonas putida
  2. Comamonas testosteroni
  3. Citrobacter freundii
  4. Enterobacter cloacae

These four microbes proved (after many hundreds of generations of selection) to have the ability to unlock bound-up phosphorus for plants grown in soil. As with many soils, when fertilizers are added the soils and other growth media can make up to 70% of phosphorous almost immediately unavailable to plants due to natural chemical binding and transformations. When phosphorus binds in the soil and other substrates, plant roots cannot assimilate it for growth. This is a huge problem in agriculture but with the microbes in Mammoth P which have been selected to unlock this bound-up nutrient, transforming P back into plant available forms maximises plant nutrient uptake to significantly increase plant yield!
