Here’s an interesting method of thinking outside the square with your own DIY worm farm.
In the video below you’ll see the conversion of an old bath tub into a pretty nice, decent sized worm composting operation.
If you have a lot of organic waste material to process, and a standard size worm bin just isn’t cutting it anymore, this could be a nice cheap option to up size your operation and provide you with more than enough worm castings for a large garden (especially if you’re also brewing worm tea too).
You could also downsize this concept using an old sink, or even up-size it further using an old chest freezer.
