I have a worm farm. Yep, I've gone over the deep end.
My theory is that worm farming is the only sort of farming I can do without developing any sort of attachment to the livestock.
Also, their poop is worth its weight in gold. And they eat garbage.
It seemed like a whole lotta gain for very little effort. And so, I brought home a worm tower, and a container full of red wigglers. They'll be living in the basement as soon as their bedding (some of which was outside in the compost bin) warms up.
