I like to grow organically outdoors. For the past 2 years, I have been vermicomposting to get both a great tea for my gardening as well as the actual worm castings...my produce tastes and smokes better too.
I just went to the hardware store and got a big rubbermaid container (30 gal), drilled drainage and air holes, and added a little dirt and shredded newspaper, one pound RED WIGGLER worms (not nightcrawlers), and vegetable garbage. Now I have worm tea and castings all the time. Worms break down the garbage into a form that plant roots can easily ingest.
Make sure you drill the holes the right size. 1/4" for bottom drainage and 1/16" for air vents around the top. Before you add the bedding cover the bottom of the bin with a screen mesh to keep the worms in. Alternatively, for air circulation, I discovered another piece of screen covering the top between the lid and container also work well and would save you drilling lots of tiny 1/16" holes. I just keep the lid ajar so there is an inch gap. The whole thing drains into a plastic oil catcher that you use for changing oil in your car. The drainage provides the best "tea". You need to water the bedding occasionally to keep it moist and temp should not fall below 55F. The basement is where I keep mine in the winter. In the summer, move the bin outdoors but in the SHADE. You will have red wigglers galore after a few months, especially outside in the summer.
This is where I went to get started:

But just do a search for Vermicomposting and you will get many hits and many ideas for worm bins. I recommend keeping it simple like I did. Oh BTW there's no smell.
