DIY Flow-Through: Lessons Learned
Currently, I am having a problem with my new DIY FT -- the compost is falling out of the bottom, often with the worms, too.
I spaced the bars well apart because of issues others have reported. In retrospect, I would recommend a design which enables you to remove bars in the future. Something else which might work is using cardboard to line the bottom initially. As soon as my newspaper was mostly gone, that's when I started having issues.
