Mammoth P



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 can be used with any nutrient feeding schedule. No self-respecting grower should miss out!

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 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 total number of these bacteria combined in the solution is a staggeringly high 200,000,000 CFU/ml. 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.

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.


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. Not only do the bacteria make use of the released elements, but your plants do too!

The enzymes produced by the bacteria in Mammoth P are, in most cases, more diverse than other standalone enzyme products on the market. 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 an 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.


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! 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.
