I have almost 100% organic garden and use variety of methods to enrich soil including brewing compost tea; using worm castings; adding biochar; using mulch; compost; using Humic / Fulvic acid; etc. I use organic fertiliser only eg Espoma brand which contains good microbes. I do use additional Mycorrhizal fungi; and variety of commercially available good bacteria to keep soil enriched and alive. I had a problem with one very rare plant that had recovered from Root-knot nematode infection previous year. This year, leaves were mostly dropped with remaining half dead. Plant was dying. I inspected roots and no sign of root knot nematodes. Tried everything possible to revive the plant, including adding good mycorrhizal fungi and bacteria, but no luck. Then I came across a user review that had used cocktail of Mammoth P, Dynomyco Mycorrhizae and Myco Supreme. His assessment was that Phosphate enriching bacteria in Mammoth P, was good complement to the latter two. I had used latter two also, so tried adding Mammoth P, for last try. Wasn’t expecting anything. Magically plant suddenly became alive! It started sprouting from every node !! To make sure this was not just a coincidence, I tried the same cocktail on some other plants. Same positive result!! Dynomyco and Myco Supreme are both good but the combination with Mammoth P, made the magical difference for me. Mammoth P has consortium of bacteria that are 30x more effective in releasing bound phosphorus. This feature must have combined with the power of mycorrhizae, to feed the roots and explode the plant growth. Definitely will continue to incorporate Mammoth P to all my VIP plants. It may be expensive but priceless when it can save difficult to replace plant. Worth every penny.

Mammoth P is the most unbelievable product that has touched and blessed the market of cannabis and other plants alike. My plants love this it is like ambrosia to them. They particularly like this during the flower stage when the phosphorus is most needed. Agro with mostly microbial products, and I grow with all organic products. Mammoth P is the way to get those rock hard buds you have been looking for. Hard sturdy branches to hold them up. This is a way to liberate all of the nutrients that have been locked away in your soil, unable to feed your plants. I would not suggest using this and adding another fertilizer with extra phosphorus of any kind as this increases phosphorus so incredibly much. If you are using build a soil or something like that Or are you are a No till living soil grower Honestly, this is the product for you. This really lends itself more towards Soil growing not that hydroponic feeding tube style of growing. The real way to Grow plants has returned lol.
