In the Oct. 9, 2007, This Old House e-mail newsletter, one of the under $500 green projects was "Build a Worm Bin". I'm interested in trying this, but want more info before starting. The paragraph in the article gave a supply list to build a plywood box with a hinged top.

1) Is this plywood box just as good as the plastic bins I saw for sale at the link provided (

2) Is there a good book that explains how to setup/mantain a worm bin?

3) Is a worm bin to be setup indoors or outdoors? (I live in SE Wisconsin, so it can get cold from October-March/April)

4) How bad does the resulting compost smell?

Thanks in advance for your help!
