I've got my worms. Woo hoo! They were hand-delivered on Easter Sunday...and they're so much fun!
Let's start with a definition, for those who are new to this concept.
Vermi refers to worms. Composting is the decomposition of organic materials into a fertilizer-rich material. Ordinarily, composting is a thermal process, in which the materials decompose through heat.
In vermicomposting, worms do the decomposing. They eat, they poop, and oh, how green your grass grows.
Types of Worms
The very best type of worm to use is the red wriggler worm. These little guys will eat half of their weight in food scraps per day. Holy crap!
The worst kind of worm to use would be the big fat ones in your backyard. The don't decompose things, they only eat things that are ALREADY decomposed. So you'd have to wait a while for them to start eating, and things would definitely smell.
Red wrigglers is the common name for the good ones, and doing a search for that will bring you tons of results.
Where to Find
Where do you find these guys? Online, mostly, from what I can tell. I've only found one place nearby to me that has them, and they're an hour away (fyi, that would be The Worm Factory in Westport, Ontario). They do accept orders online (Ontario folks only) and by phone (for all other folks). I'm guessing that sending worms across borders might be a bit of a problem though - just google it, in your area.
Most places seem to charge about the same amount for them: $25-ish for 1/2 pound, $45-ish for a full pound.
Housing
Worms need a home. Worm homes need to be well ventilated so the composting process doesn't turn to rot (aeration is the key word here) and begin to smell. Worm homes also need to be dark because the little guys don't like light. Clear b oxes are not ideal. For singles and couples, recycling a couple of buckets from Tim Hortons will do a good job of housing your worms and taking care of your scraps. For a larger family that produces more scraps, a large, shallow storage bin with a lid will work great.
Ventilation
Whichever you choose, you will need to ventilate. In the picture here, you can see that I went nuts with a drill and put a million holes in the top of a Rubbermaid bin. (I started out with a nail and a hammer, and got about 15 holes done before my fingers hurt and I was just annoyed. The drill was WAY more fun.)
The holes that my drill made (I think I was using my husband's second smallest drill bit) seemed good for airflow (not too small) but too big to keep the worms contained, should they decide to make a run for it. So I stopped off at Canadian Tire and bought a roll of screening for doors and windows. I cut a piece slightly larger than the area where the holes were drilled, and used sandpaper to roughen the plastic around the holes. I then smeared some carpenter's glue (because that's what we had in the junk drawer) around on the rough parts and pressed the screen into it. I left it to dry in the sun for a day, after which the smell from the glue was mostly gone.
So far, so good, although we've only had the worms for three days now. At this point, I do have a concern that I have some long, skinny bugs roaming around in there, and I haven't completely decided what they are or what to do about them. Seems that adding more dry bedding (shredded newspaper, dry leaves, etc) and sprinkling eggshells or calcium carbonate (to reduce the acidity of the environment) is often the answer to a lot of problems.
Anyway, I'll keep things updated here on Life with Worms. :) My kids are totally pleased about it though, and my neice even seems to be coming around. My husband doesn't care so long as he doesn't have to have anything to do with it.
