Description
Mammoth P – Microbial Phosphorus Unlocker
Mammoth P is a powerful microbial additive designed to unlock bound phosphorus in your growing media, making it instantly available for plant uptake. Built for soil, coco, and hydroponic systems, it enhances nutrient efficiency, improves plant health, and drives bigger yields and better flower development.
Developed using a targeted blend of beneficial microbes, Mammoth P helps convert unavailable phosphorus into plant-usable forms. This leads to stronger root development, tighter internodal spacing, and increased floral production.
Why Use Mammoth P?
- Unlocks bound phosphorus in soil, coco, and hydro systems
- Boosts nutrient uptake and overall plant efficiency
- Encourages shorter internodes and denser flower sites
- Supports increased resin production
- Helps protect the rhizosphere from harmful pathogens
- Works across the full plant lifecycle from veg to bloom
How It Works
Phosphorus is essential for plant growth, but up to 70% of it becomes unavailable due to chemical binding in the growing medium. Mammoth P introduces a specialised microbial consortium that breaks these bonds, releasing phosphorus back into forms that plants can absorb.
This microbial action increases nutrient availability, improves root-zone health, and enhances overall plant performance throughout the grow cycle.
Key Microbial Strains
- Pseudomonas putida
- Comamonas testosteroni
- Citrobacter freundii
- Enterobacter cloacae
How to Use
- Hydroponics: 0.16ml per litre of water
- Soil / Coco: Start low and gradually increase up to 1ml per litre at peak flowering
- Frequency: Use throughout vegetative and flowering stages
Pro Tips
- Works exceptionally well in coco where phosphorus lockout is common
- Combine with your existing nutrient schedule without adjustments
- Near-neutral pH means no disruption to your feeding regime
