NANAMAN, let me know what you have to work with as far as a site to raise them and I'll help you put in a bed. In my gallery you can see an off building in our backyard. I hope to have the building full of worm beds by fall. Now, when I say full, I mean floor to ceiling. Right now we are building beds that are basically large drawers. Think of a huge chest (no not Pam Andersons) of sliding drawers about 5 deep. The wooden indoor bed is 3x8'. What we are building is a stack of 3x4' drawers as tall as we can work.
These things breed so fast, that by this time next year (even while selling our stock) we should have that building packed to capacity!
As far as your castings go, Mitchell, I think makes his own in a bed, can o worms will be slow producing. Go for something bigger!
A bed 8x3'x12" should yield about 600lbs of castings a year! You have to feed a lot of matter to be composted, but hey, look up worm castings and you'll find you can't beat it for fertilizer.
Where you live you may be able to put some right next to the plants you want to fertilize. Of course you'll need to make sure they have organic matter and constant moisture.
A friend of mine took his worms and put them in rows of horse manure and hay about 50' long, with no sides or tops, just a row of piled horse poop. To this day they are still doing great. It's been over a year now.
I don't know if his site is still up, and since we're competing for sales I shouldn't post his site here, but I want to give you more ideas on what you can do. You can look at his at
www.fiddlersfarm.com . I took all the pics (BTW, and he really is a sharp guy). With my old ran-over, smashed-up, beat-to-death, no-longer camera.
Anyway, you have many options and the worms really won't care.
Let me know if you need plans for a bed or anything else that has to do with raising worms.
BTW. Just let me add. Worms are sooo ICKY!!! Although they are making us $$, they are still gross! When we open our beds and lift off the carpets, it sounds like a bottle of soda when they all start running for the dark. Creepy!
