I have been successfully vermicomposting on a small scale with a Can-o-Worms and red wigglers for a couple of years now. Recently, I started paying a lot more attention to "loading" my bin with food and the worms are having a ball. And, apparently, orgies, since I have a LOT more worms and baby worms.
My bin doesn't begin to process all the compostables that comes through my house, nor does it provide the amount of compost I'd like to see, so I want to upsize. That means moving down into my basement which is cool in summer and a tad chilly in winter, although it is heated. It's probably not warm enough for their ideal conditions, but I think it'd be okay.
I've been looking at bin designs and I can't really get a sense of the pros and cons of having one large bin in my basement versus several small bins. One large bin seems to be easier until it comes to cleaning it, and obviousy the temperature would be more stable. Whatever it is, it has to fit through a 30" door. If I had a long bin I could use the trough method to move the worms from one side to another.
Any thoughts on one big bin vs. several small bins?
