Mammoth P Microbes

  • Mammoth P Microbes

MAMMOTH P MICROBE outgrowing the competition. It is the first organically derived microbial inoculant that boosts phosphorus and micronutrient cycling to maximize bud growth, increase yield, and enhance plant health.  NOW AVAILABLE!!

So what the hell are Mammoth P Microbes and why all the fuss?

Phosphorous is awesome for plants but is hard for plants to uptake due to its double bonds (which takes A LOT of energy to break). So what if we could break these bonds first and save your plants all that effort?  The sole purpose of Mammoth P Microbes is to liberate & mobilise phosphorous and give it to your plants in mass. The results of this are quite staggering to say the least. Four very specific microbe families that live solely to give your plants their favourite flowering stimulant…phosphorous! You just sit back and let them do all the hard work while you reap the rewards….
