I just started raising worms this year. I had an old livestock water trough that was no longer being used. It's one of those rubbermade black ones. I cut the bottom out leaving about a 2" rim around the bottom. I attached screen to this so it would drain but the worms couldn't crawl out. I then set it all on a pan that would catch all the liquid and funnel it to one drain hole. I am in the learning process with vermiculture, but so far this seems to be working fine and the worms are doing okay considering the fact that I have the bin in my garage and the temps have been over 100 for days. I will be adding more bedding soon.
From the setups I have looked at online I'm hoping I can find an old bathtub that I can use in the future. Those look like they work very well.
