The only issue with Mammoth P is its 97% water. Ur paying allot for 3% of microbials..
Actually it's 1% Microbes, 2% Alfalfa extract, and 97% h20.
and not to be an alarmist but some of the strains of microbes within Mammoth P can affect human beings. (Citrobacter freundii, Comamonas testosteroni).
you could make your own microbes for way cheaper and better than a bottled product.
