I am thinking it will be good for them but I will hold off until I get some info my guess is that the worms should eat and enjoy it Not sure if anyone has trie that?
I've only just started my first worm bins the other day and the new worms had no problem with the bedding I setup for them using water from the sump tank of a Koi pond. Already have evidence of the worms eating their fill after only 2 days in the bins. I'll let ya know how they are doing in a week or so.
