Effective microorganisms (EM) are the key to a composting or decomposition process known as "bokashi" in Japanese. During this low-odor, air-sealed process, your organic kitchen waste in particular is transformed into high-quality fertilizer, soil conditioner and compost accelerator. The liquid produced during the fermentation process is continuously passed through a filter mesh, collected in the drawer of the Bokashi bucket and regularly filled - in the irrigation water it proves to be an excellent liquid fertilizer. If the filter is undamaged after a completed fermentation cycle, it can be reused; damaged filters should be replaced for successful fermentation. The filters are made of pure viscose, so they are also biodegradable - you can mix old filters into the substrate or dispose of them in the organic waste. You will receive a supply of new filters tailored to our Bokashi bucket with this set.
