I know that there used to be directions somewhere, on this forum, on making homemade earthboxes. I cannot find them any more. I know I can find them on jomalt's site but there is just so much there that it is confusing. My daughter wants directions after seeing how well mine work, but mine are a mix of different kinds and I was sure I could come here and see pictures that would help her. She does not live near me, so I can't just show her what to do.
Homemade grow boxes
There's a whole forum devoted to earthboxes and various equivalents--maybe the thread you're looking for is there somewhere? http://davesgarden.com/community/forums/f/boxgardens/all/
