I have never researched or used bokashi, all I know is that you ferment some stuff and add it to soil? If you're interested in making your own nutrients you should look into making some LAB serum. Heres a great article on how to make it.. https://www.dudegrows.com/soup-lactobacillus-culture/ this lactobacillus culture serum is literally just beneficial microbes in a bottle. Once you've made some LAB youve taken the first step into KNF (korean natural farming). This farming practise uses plant, mineral and animal (fish) to make all natural fermented plant food.
