Tell me a bit more , how does this work ? what kind of worms?
Do they stay there year round?
I've been composting in bins for years and just recently learned about the tubes. Food is added to the tubes and the worms travel in and out through the holes, and deposit nutrients to the soil within a 3' radius. I did add handfuls of red wrigglers from my bins to each of the tubes along with the chopped up food scraps. I use a hand crank auger each time I add food, and next spring I will also use the auger to empty each tube. So far when I add food and mix it in, I've seen a increase of worms in the "diners" (tubes). I'm not 100% sure that the red wrigglers will survive the winter, but my thoughts are that they should.
