Vermicomposting, worm bin, composting with worms community and forums
I have a friend who started vermicomposting last year. We live in Canada and she had heard that it wasn't safe to keep your worm bin inside because it could give off a dangerous level of CO2. Therefore, she moved her bin outside and the worms froze to death :(
Now I know a number of us keep our bins inside (myself included) but is there any foundation for her concern? Do the worms give off CO2 while eating the microorganisms? Has anyone heard of this? Would it have to be a massive setup to create a problem?
She wants to get back into worm composting so I thought I would ask everyone's expert opinion.
