Ah! I couldn't tell from the pic lol the bokashi that came with my BAS kit didn't look like that. I'm trying out making labs from oats as I read you can use pretty much any grain interchangeably. I figure the oats have a higher nutritional value than the rice would. Also started an apple J as its what I had on hand, and some FPJ from the huge leaves I took off the plant in the 2x2.Bokashi its microbes you add to wheat bran and dry it then you can add it to your soil. The microbes (LAB a KNF recipe) is a dynamic composter and breaks down amendments and old roots left in your soil faster. Bokashi also encourages all the fuzzy white stuff. It is fairly cheap to buy but since I make LAB from time to time anyway I just started making bokashi then I can add it to my soil whenever needed without going through the rice water and fermenting stages of LAB. I do not know if they are directly interchangeable working on figuring that out.
I have a bulk bag of Mycorrhiza(from buildasoil of course) I use as well when I first drop in a seeding. Those are the only beneficial I add anymore. I seem to get as much activity from those two things as I did all the expensive stuff you can buy.
