Mammoth P Microbial Inoculant

Unlock the phosphorus already sitting in your growing medium

Mammoth P is an organically derived microbial inoculant built around four naturally occurring bacterial strains, Pseudomonas putida, Enterobacter cloacae, Citrobacter freundii and Comamonas testosteroni, that solubilise phosphorus and micronutrients already present in soil, coco or reservoir and convert them into forms roots can actually take up. Rather than adding yet more fertiliser, it makes the feed you're already running work harder for bigger, denser flowers.

Key Benefits

• Phosphorus solubilisation unlocks bound-up phosphate for stronger bud and flower development
• Micronutrient cycling improves uptake of iron, zinc and manganese alongside phosphorus
• Broadly compatible with soil, coco and hydroponic reservoirs
• Organically derived and safe to run with most base nutrients and additives
• Stable formulation with a long shelf life when stored correctly

Poor uptake and stalled flower set despite a full tank?

Even with a balanced feed, phosphorus can be locked out by pH swings, cold roots or salt build-up, leaving plants stretching with weak flower set and low yields while nutrient sits unused in the medium. Mammoth P works alongside your existing feed to keep that phosphorus available throughout the crop rather than tied up out of reach.

How to Use

• All media (soil, coco, hydro): dose at 0.6ml per gallon (roughly 0.15ml per litre) of nutrient solution
• Frequency: apply weekly from early growth right through to harvest
• Mixing: shake well, add directly to the reservoir or watering can with your regular feed
• Tip: compatible with most base nutrients and additives; avoid mixing directly with strong hydrogen peroxide or sterilising agents that would kill the microbes
