Mammoth P is a unique combination of powerful microbial life forms, purposefully selected and designed for both soil and hydroponics systems. Studies (and feedback) confirm that typically when using Mammoth P, you will notice a whopping 16% increase in your final harvest! Combine that extra yield with Mammoth P’s high concentration; a small bottle makes for a priceless addition for your plants. Completely OMRI certified, Mammoth P is a powerful, organic microbial additive that no self-respecting grower should miss out on.

Born from cutting-edge research performed in Colorado, Mammoth P is a powerful and unique bacterial based growth enhancer. Years of selective breeding on a bacterial level has led to a unique combination of bacteria that are highly adapted to modern day agricultural farming. They are cultured and selected to be highly suitable for both organic and more typically hydroponic growing methods. Enzymes produced by these bacteria can rapidly break down phosphorous and other micro nutrients that are otherwise locked away in the root zone – significantly improving yield and quality!


At its core, Mammoth P is a combination of four highly specialised bacteria, which promote fast and vigorous growth in plants, throughout their entire lifecycle. The bacteria have been selectively picked and cultured over many generations to achieve species that thrive in substrates and conditions where other species would not be at all suitable. Starting from over 10,000 strains of bacteria, only the hardiest, vigorous and most beneficial bacteria were selected over many years of intensive research until these final cultures were chosen.

Each culture was selected based how well they release locked up nutrients from the substrate into the nutrient solution, and how well they survive in ‘extreme’ environmental conditions. The bacteria strains have been cultured and selected specifically to thrive in a more aqueous and ion-rich environment, making them uniquely suitable for applications in more hydroponic environments, as well as maintaining full function in a more typically soil environment. It will leave no residue when ran through an irrigation system, refreshing your reservoir every 7-10 days recommended.

The different types of bacterial cultures are concentrated, supplied with a food source and added to a solution. The food source is an extract of Alfalfa, making up 2% of the overall solution. Alfalfa is well known to have its own beneficial horticultural properties, so it makes an ideal choice as a food source for the microbes cultured in the solution. There were four species of microbes that made it through to the final culture: Pseudomonas putida, Comamonas testosterone, Citrobacter freundii and Enterobacter cloacae.

The total number of these bacteria combined in the solution is 200,000,000 CFU/ml. This is a staggeringly high count/concentration of bacteria! The highly concentrated solution is to be used throughout the entire life cycle, promoting healthy, vigorous growth and an optimum harvest. These are primarily carbon feeding bacteria, supporting the plants with a whole host of functions, mainly being responsible for freeing up nutrients that have become bound to the substrate and locked away from use.


The four types of bacteria work mainly by releasing particular elements that have become bound to the substrate, making them available again in the nutrient solution immediately surrounding the root zone. The way they do this is by producing enzymes that break down bonded elements into their constituent products. Enzymes are like little biological machines. They are made by the bacteria to perform specific jobs, like break down surrounding bonds to release various elements. Not only do the bacteria make use of the released elements, but your plants do too!

To really understand these bacteria, you need to understand their relationship enzymatic activity as well. Enzymes are not ‘life’ in the same way bacteria are. They are however responsible for life to flourish, by doing the majority of life’s hard work for it. As mentioned, enzymes are almost like machines of nature, slaves to life, created to get most of the dirty work done for it. in this case breaking down potential food sources for the bacteria and plants – a bit like microscopic knives and forks.

The enzymes produced by the bacteria in Mammoth P are, in most cases, more diverse than other standalone enzyme products on the market. Β-Glucosidase, Phenol Oxidase, Phosphatase, N-acetyl-Glucosaminidase and Leucine Aminopeptidase are the powerhouse enzymes in Mammoth P. Each one breaking down and releasing its own particular element, that when used in combination maximise a wealth of processes throughout your plant.


All of this enzymatic and bacterial activity hugely increases micro nutrient availability, and crucially in increased availability of phosphorous. Micro-nutrients are well known to be vital to proper plant growth and development, maintaining the optimal availability of these elements is, of course, crucial to optimal plant growth. It doesn’t stop at micro-nutrients either, increased amounts of the phosphor are also made available, a macro nutrient essential for many critical plant processes.

Phosphorous is required by the plant at the genetic level, being responsible for linking DNA and RNA together during cellular level development. Obviously, cell growth and development goes on throughout a plants’ entire life cycle, so without an adequate supply, your plant will struggle to correctly express its true natural splendour on its most fundamental of levels. Other typical deficiencies seen through phosphor (such as purpling stems and stunted growth) are completely negated with the production of the available phosphor by Mammoth P.


The benefits of Mammoth P don’t stop merely at the nutritional level. Simply the presence of these beneficial and super productive bacteria in your media will discourage the presence of any root diseases and pathogens, such as fusarium wilt or Pythium. By out-competing the bad bacteria that are the cause of diseases, you will go a long way to ensure you do not fall victim to root rot. The result is brilliant white roots that mean your shoots and fruits get everything they could ever need.


With the grower firmly in mind, Mammoth P have produced a highly concentrated blend of microbes, meaning a little goes a very long way. In hydroponic environments, it is applied at a rate of 0.16ml per litre! It is used at this rate throughout the entire growth cycle, alongside your usual nutrient regime. You may notice that with the increased availability of nutrients Mammoth P generates, you may need to slightly reduce your usual EC rates, saving you further money on the otherwise wasted nutrient. It is recommended to change your nutrient solution every 7-10 days.

In soil applications, its application rate varies slightly throughout the life cycle of the plant. Following the Mammoth P feed chart of the product, you increase the concentration slowly up to the maximum rates at peak flowering times, where it is then tapered back down during the flush period. The most you will ever use at one time is 1ml/L, making a highly cost-effective microbial additive. Mammoth P has a near neutral pH range and as such will not interfere with your usual nutrient regiment


Store Mammoth P away from direct light, UV in particular. Always store in a cool, dry area to prolong the shelf life and effectiveness of the product.

Being an organic bacterial product, its maximum effectiveness will be noticed within six months of purchase.

Hold your nose when using! The bacterial nature of this product means it doesn’t have the most pleasant of smells, but your roots love it!!
