New to Vermicomposting - have questions
I'm going to start vermicomposting. I have two main motivations for this venture. My mom would like the worm casting and tea for her garden/plants and I keep hermit crabs and the casting are used for several applications in their care. Because of the second reason I'm hesitant to use newspaper or paper products that may have been exposed to chemicals that the hermit crabs are sensitive to in my worm bin. Are there alternatives to newsprint or cardboard that I can use to line my bin? I'd also like my worm castings to be as hermit crab safe as possible because there is a possibility that I can sell any surplus worm castings to other hobbyists in the future.
