I've made bokashi flakes from bran and LAB liquid, been using it for a while.
Dried the flakes and stored in plastic boxes, but I am unsure if that is the best way to store, since I know the bacteria inside does not like oxygen, and clearly a box has oxygen.
It also made me wonder - How long bokashi flakes can last?
Additional details:
Daytime time temperatures: summer 30-40c, winter 4-15c
Night time temperatures: summer 27-30c, winter 3-9c
Humidity: ~65-85%
Bokashi flakes were made from home-made LAB liquid from rice water, fructose syrup & wheat bran mixed with water, inside garbage bags for some weeks and then sun-dried and stored in small boxes, placed in a closed shed.
