16% Increase in Yield. 6% Increased Stem Strength. 100% Satisfaction Guarantee.

Mammoth P is the first organically derived microbial inoculant that maximizes phosphorus and micronutrient cycling to maximize bud growth, increase yield and enhance plant health.

Why Mammoth?

Mammoth P differentiated from other microbial biostimulants because it is a microbial consortia that was specifically developed using a functional trait selection platform and has been rigorously tested (by scientists at Colorado State University) to mobilize P (Phosphorus) and other micronutrients for plant uptake. Mammoth P was specifically tested and is proven to increase yield by 16% across all management practices (coco, hydro, peat, etc) and nutrient lines in the bloom cycle.

How Does it Work?

MAMMOTH P™ is the first organically derived microbial inoculant that was specifically designed to unlock P (Phosphorus) and micronutrients to maximize bud growth.

Mammoth P is a liquid formula of beneficial bacterial that can be applied directly to soil, coco or recirculating hydroponic systems.

The beneficial bacteria act like micro bioreactors, continually producing enzymes that release nutrients. Increased levels of P keep internodes shorter and focus energy on bud production.

Mammoth P naturally accelerates the nutrient supply to plants to increase plant health, bud size and quality and yield. Field trials with many growers across the Front Range have demonstrated that Mammoth P increases plant yield by an average of 16%.


“I’m very excited! I’ve given my plants it twice now and I already can tell a difference! The plants are looking fabulous! Frosty as ever in bloom at 39 days. And green and growing like crazy in veg. cabinet.” – Anonymous Grower

“I am absolutely LOVING Mammoth P and plan on using it from now on. It works so well with my setup. I am currently running Super Soil from Build A Soil with a few additives including Recharge. Originally heard about you guys on the dude grows show – I’m a long time listener. Thank you very much for the samples you sent me. The first time I used your product my plants absolutely EXPLODED with growth! I highly recommended your product within my small circle of growers.” – Jamie

“I did not get a side by side, but I did run the same strain in the same soil mix on two separate occasions. I ran it without any beneficials and just AACT, then I ran it with AACT, Mammoth P, and SLF100. There was such a marked difference in not only stem strength and yield but also in overall quality of bud. I had people accusing me of lacing the bud after a small sample. MammothP has earned a regular spot in my organic growing.  Thank you for such an awesome product!” – Anonymous Grower from Alaska

From a hydroponics grower – he is seeing a bulking and increase in density with his buds. He likes the product and will be continuing use from now on. He is using the Botanicare Kind 3-part nutrient system along with Botanicare additives and Mammoth P™. He has grown these strains before, and although he has not harvested yet, he knows there is an increase over past runs.

Whats the Shelf Life?

Mammoth P is a very stable and organically derived natural product. Mammoth P stable shelf life data currently extends 16 months from manufacture date.

How Should I Store It?

We recommend storing at room temperature- ideally out of direct sunlight and away from hot or cold extremes.

Should it Smell so Much?

The bacteria in Mammoth P do have a strong smell, as they are very active and highly functional for promoting plant growth.

Is it Dangerous?

No. But, avoid contact with eyes, mouth, and broken skin. Do not inhale product. Wear eye and skin protection when handling. Wash hands after using.

Will it Cause Tank Slime?

No. 100’s of growers are adding Mammoth P to their reservoirs and seeing great results. Adding Mammoth P should actually reduce tank slime. The microbes in MAMMOTH P™ can unlock bound nutrients (actively cycling nutrients and any build up) maximizing P and micronutrient availability to increase plant nutrient uptake and plant yield.
