What do you think about using bokashi to ferment citrus, potato peels, and onion skins ect... You know, stuff that you wouldnt put in the worm bin.
Well I don't see a problem with it but, I've never incorporated citrus or onion. Potato peels, I have actually chopped up real fine with banana and oats, sorta made a slurry and the worms gobbled that down in a week.
If it were me tho, I wouldn't add in those 2. Bokashi should be made and formulated based on the nutritive value of the ingredients. This would be a good time to add things like garlic, cilantro, mint, rosemary... these help the soil fight pests.
Remember that a sugar source is very important with fermentation, some scraps will have a high natural sugar content like cantaloupe and strawberries, so you need to adjust for the total volume that doesn't have natural sugar. Add in either molasses or a sugar source of your preference. I like agave nectar alot!!!!
