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

MAMMOTH P was developed by Growcentia’s founders at Colorado State University using next-generation technology. MAMMOTH P has been tested extensively by Colorado growers and independent labs have proven to increase plant growth. All production is done at our facility in Fort Collins Colorado to maintain the highest level of quality control. This beneficial bacterial formula works great in soil, soilless, and hydroponic systems. Using MAMMOTH P in hydroponic systems is an excellent way to introduce the organic benefits of soil microbial nutrients without sacrificing water quality. MAMMOTH P was engineered to supplement any fertilizer program.

  • Designed to increase phosphorus availability during bloom phase
  • Use as a supplement to your regular fertilization program
  • Does not effect pH
  • Works in soil, hydroponic systems and soilless systems
  • A little goes a long way... 8.5 oz treats approximately 400 gallons of water
