MAMMOTH® P is an organically derived microbial inoculant for growing plants that maximizes phosphorous cycling to maximize growth and increase yields. The proprietary, beneficial bacteria in MAMMOTH® P are supercharged bioreactors that continually feed your plants phosphorous. Increased phosphorus is important in the flowering stage as it helps keep internodes short and allows plants to focus on flower production. MAMMOTH® P was developed by Growcentia’s founders at a leading US University and has been extensively tested and has been proven to increase yields by 16% and increase stem strength by 6%. This product is OMRI Certified.
