Hi
your wormery was dispatched today - but might not be with you until monday - our couriers have been having problems with all the snow !!
Bokashi won't harm the worms at all, in fact they really like it, we feed our worms on our bokashi waste.
however make sure that you don't add too much, as we have found that bokashi creates a lot of heat as it continues to compost down, so make sure you add it to 1 or 2 corners, so that the worms can escape if too hot
regards
ronnie
