I made my own bokashi. Very simple to do and very cost effective. I use 5 gallon painters buckets with lids to store the compost. Very clean, no smell - which my roommates appreciate
I've had the compost covered in bokashi in a sealed container for about 3 weeks, so I believe it is ready to be used, based on what I have read. For soil, I was planning on buying some organic soil from Whole Foods.
